3 depict such a positive relationship. As we know, dew point depends upon both relative humidity and air temperature but the result discloses that dew point is greatly controlled by air temperature rather than relative humidity. The higher the value of adjusted , the better is the fitness of data points. Solar radiation is the ultimate source of energy for the planet. Finally, it fell sharply to attain the second minimum values of 13.65°C. relationship between solar radiation and temperature in Perlis, Northern Malaysia for the year of 2006. In addition, the in‐situ measurement of solar radiation is highly desirable for the compensation in a SI‐traceable manner. Solar radiation is the ultimate source of energy for the planet. In conclusion, the solar radiation exposure of a monitoring station is an important parameter that must be considered both during the instruments siting and the analysis of data collected by sensors previously placed. However, studies of temperature and other parameters at more local scales are also needed to be given the fact that broad-scale analyses may mask considerable spatial and temporal variation in climatic trends [18]. Perihelion is in early January, hence northern hemisphere winter (Nov-Dec-Jan-Feb) has a higher solar radiation level at TOA than does northern hemisphere summer, southern hemisphere summer has a higher solar radiation level at TOA (top of atmosphere) than does southern hemisphere winter (June-July-August). Hence, it is also clear that dew point is significantly correlated with solar radiation. Previous studies also suffered from limitations in the methods of data analysis. A solar radiation sensor (pyranometer) was used to determine the solar radiation for shortwave radiation which has a spectral range of 305-2800 nm and radiation range of 0-2000 W/m2 with 5% accuracy. 3.2. Cross-Curricular Connections ... Air temperature is not affected by elevation (AAAS Project 2061, n.d.). Measurements from NASA's Solar Radiation and Climate Experiment show that solar UV output is more variable than total solar irradiance. Correlation matrix of climatic parameters. The values of Pearson's correlation are +0.50 (annual), +0.60 (spring) and +0.74 (summer). Similarly, another sensor was the air temperature and relative humidity sensor to determine the temperature and relative humidity. However, afternoon, air temperature gradually decreased all night and indeed occurred the least value during the early morning. Therefore the curve of solar radiation against temperature is a loop (hysteresis), as shown in Fig 1 for monthly mean values in Berlin. Location of the study area in the map of Nepal. From the statistical point of view, we can say that the quality of the measured data is relevant. Overall, in Damak, we receive the moderate as well as extreme climatic condition throughout the year. 1) Relationship between photoperiod, temperature, solar radiation and grain yield in soybean Photoperiod and temperature influence the growth, development and area of adaptation of soybean cultivars (Shanmugasundaram, 1981). Its variation during 24 hours is shown in Figure 3(d). During the month of May, June, July, August, September, and October, temperature difference went down below 10°C, and these months especially represented the moderate climatic condition due to rain and cloud in summer. The solar radiation data can also be used to estimate the solar energy potential at Damak to promote solar photovoltaic cells. Again, the increasing or decreasing trend of solar radiation is almost symmetrical on a sunny day. The relative humidity and dew point temperature are widely used indicators of the amount of moisture in the air [11]. [22] rather than Gaussian fit (adj. The relative sensor measures variance in the capacitance change of a one micron thick dielectric polymer layer. Many studies on recent temperature and solar radiation trends have been carried out all over the world. Consequently, it can be inferred that the trends in DTR were influenced by changes in emissions and the associated changes in incoming solar radiation. From the statistical point of view, it is concluded that in a clear and sunny day, the variation of solar radiation and relative humidity follows the Gaussian distribution but the air temperature variation is governed by a sine function. It also measures 100% range of relative humidity with ±2% at 20 to 80% accuracy and resolution of 0.5% RH typical and has long-term stability RH/year with repeatability of ±0.1% having digital output.

A more commonly available measure, which may provide such information, is the diurnal temperature range (DTR). The maximum and minimum temperature of each month is estimated by taking the maximum and minimum temperature of each day and calculating the average value over the period of one month. The lowest value of the relative humidity (55.4%) in April indicates the driest month of the year. The relationship between the number of cases and the monthly average temperature, specific humidity, and downward short-wave ultraviolet (UV) radiation in each province of China, showed that COVID-19 cases were concentrated in the provinces with temperatures in range of 0–10 °C. Weather station with some components: (1) wind direction sensor, (2) wind speed sensor, (3) pyranometer, (4) air temperature and RH sensor, and (5) data logger. It was found that the linear correlation coefficient value is 0.7473 shows that a strong linear relationship between solar radiation and surface temperature. An idealised hysteresis is shown as … of the observed and online calculated value of dew point tells us that 99.8% data gives the exact fit of a linear relationship. The relationship is Tt = A [1— exp (— BΔTc )] where Tt is the daily total atmospheric transmittance, ΔT is the daily range of air temperature, and A, B, and C are empirical coefficients, determined for a particular location from measured solar radiation data. Dew point was also calculated from the actual readings of air temperature and relative humidity using the online calculator, and the calculated value showed the exact linear relationship with the observed value. Monitoring and prediction of the climatic phenomenon have developed over the years; as a result, wide knowledge and information have been gathered that have helped to understand and to predict it. Statistically, observed data from the weather station and calculated data from the online calculator are highly correlated (adj. ) The ground-based weather station is a very reliable and authentic source to generate the meteorological data for climatic research, and still, it is used to collect the data from different stations for the study of spatial and temporal variation. Dew point temperature is the function of RH and air temperature. The relationship is T t = A [1— exp (— BΔT c )] where T t is the daily total atmospheric transmittance, ΔT is the daily range of air temperature, and A, B, and C are empirical coefficients, determined for a particular location from measured solar radiation data. The variation of solar radiation during 24 hours in the clear sky day always followed the Gaussian fit [21] in which adjusted value was 0.9899. The dew point temperature shows somewhat complex behavior. Since the scatter plots represent the straight line, the linear regression model was selected to estimate the It is influenced by the location latitude, elevation, and proximity to water bodies. CORRELATION BETWEEN TEMPERATURE AND SOLAR RADIATION By using the Pearson's r correlation, it has been found a relationship between the solar radiation and temperature. between trends in SO2 emissions, radiation and DTR in areas affected by high pollution. Cross-Curricular Connections ... Air temperature is not affected by elevation (AAAS Project 2061, n.d.). [1] The surface solar radiation (SSR) is an important factor influencing the local and global energy budget. In January, the coldest month of the year, RH was relatively higher and its value rapidly fell down to reach the lowest value at the month of April (55.4%) representing the driest month of the year. Dew point temperature is preferred by meteorologists over relative humidity as an indicator of human comfort [15] and also used in forecasting the rain, frost, and fog formation as well as the probability of thunderstorms [16]. The values of Pearson's correlation are +0.50 (annual), +0.60 (spring) and +0.74 (summer). For the given mass of the water vapor present in the atmosphere, the increase in air temperature always reduces the RH. Hence, the total solar radiation potential will be a key factor for designing and predicting the performance of solar energy equipment [6–8]. The variation of the daily air temperature is shown in Figure 3(b). The value of and its adj. 3 depict such a positive relationship. June, July, August, and September represent the monsoon period in Nepal. 1. We tested for additive interactions between solar radiation and air temperature, age, and gender. Monthly variation of solar radiation, air temperature, RH, and dew point in 2013. Copyright © 2021 Elsevier B.V. or its licensors or contributors. This law (expressed mathematically as E = σT4) states that all objects with temperatures above absolute zero (0K or -273°C or -459°F) emit radiation at a rate proportional to the fourth power of their absolute temperature. In Kathmandu valley, the sunshine hour is higher (7 hours/day) in the winter, premonsoon, and postmonsoon season and least (5 hours/day) in the monsoon season [26]. They are subject to many influences, including those of the atmosphere, ocean, and land, and are modified by them.

Air temperature and relative humidity are two different climatic parameters in which RH is greatly affected by the air temperature. As variation of solar radiation is the single most important factor affecting climate, it is considered here first. Available literatures show that few and limited studies have been conducted in eastern Nepal. Arun Kumar Shrestha, Arati Thapa, Hima Gautam, "Solar Radiation, Air Temperature, Relative Humidity, and Dew Point Study: Damak, Jhapa, Nepal", International Journal of Photoenergy, vol. Monthly variation of solar radiation, air temperature, and dew point shows a similar pattern, lower at winter and higher in summer. Both observed and online calculated value are highly correlated with each other. and give the relevancy of the measured data. Maturity Groups 00 to X were screened for photoperiodic The monthly observed value of RH obtained from the weather station and the online calculation is demonstrated in Figure 5. This work studies the relationship between global radiation and air temperature in monthyly values for 1973-1989 and 1977-1989 in Santiago de Chile and Salamanca, respectively. experimentally and Boltzmann theoretically developed a relationship between the temperature of a body and the amount of power it radiates. Correlation matrix shows that the dew point is significantly correlated with air temperature rather than relative humidity. To predict the values of temperature and instant solar radiation when equipment are not readily available from obtained equations, a good knowledge and understanding of the disposition and distribution of solar radiation is a requirement for modelling earth’s weather and climate change variables. Dew point greater than 60°C at lower atmosphere gives the probability of intense thunderstorms [17]. The monthly variation pattern of solar radiation, air temperature, and dew point demonstrates that they have the highest value at summer and lowest in winter. Germplasm col-lected from the U.S. The weather station is situated in the premise of Damak Multiple Campus which had been established in 2012. Weather. The highest air temperature occurred in the afternoon (1:00-2:00 PM), and it showed that even in the afternoon, the air kept net absorbing heat. Climate - Climate - Average relative humidity: The average relative humidity for July reveals the humidity provinces of the Northern Hemisphere when aridity is at a maximum. Damak is situated between 26°3521.28N to 26°4458.71N latitude and 87°399.40E to 8704310.32E longitude in the southeastern Terai region of Nepal with 130 m in elevation from sea level. The Stefan-Boltzmann law, a fundamental law of physics, explains the relationship between an object's temperature and the amount of radiation that it emits. 18 Usually, there are three different approaches to estimate the sky temperature: empirical methods, radiation charts, and computer program models. Thereafter, RH rapidly increased and attained the highest value with small fluctuation during the whole night. Comparing Temperature & Solar Radiation for Common Latitudes Purpose Examine (daytime) surface temperature and solar radiation received at locations found near similar ... What is the relationship between latitude and surface temperature? Temperature and Radiation Mike Luciuk ... experimentally and Boltzmann theoretically developed a relationship between the temperature ... Sun at 1 astronomical unit (AU) distance is: (solar disk area)/(distance 2) or Ω= 5 2 5 2 8 2 (7 10 ) 6.84 10 (1.5 10 ) sun sun area x x It is due to the fact that light is easily absorbed by the earth surface and converts into heat energy, but once the heat is generated, it is not easily escaped from the atmosphere because the atmosphere acts as a blanket and blocks the outgoing radiation. The main exposure variable was average solar radiation at residence during the past 15 years. [27] also reported the similar pattern of monthly variation of solar radiation in Kathmandu and Pokhara valley as we observed in Damak. The correlation matrix of Table 1 demonstrated that there was a strong correlation of air temperature and dew point with solar radiation with a significant level of less than 1%. CORRELATION BETWEEN TEMPERATURE AND SOLAR RADIATION By using the Pearson's r correlation, it has been found a relationship between the solar radiation and temperature. SP6557. Theoretical consideration of the energy budget equation suggests that the relationship between solar radiation and air temperature is dependent upon five major factors, i. e. the reflection coefficient, effective outgoing longwave radiation, the Bowen ratio, heat flux into the soil, and advection. Then we measured the surface temperature, air temperature, humidity and wind velocity on various types of land covers such as concrete, asphalt, soil and grass every hour for one cycle namely 24 hours. The variation of the RH can be explained as follows: at nighttime, mass of water vapors present in the atmosphere is relatively high, but at higher temperature (daytime), evaporation rate is high enough to convert water into water vapor and mass of the water vapor present in the atmosphere of given volume is relatively low; as a result, relative humidity is also low. To determine outgoing radiation power , we utilize the Stefan-Boltzmann Law: P A T=εσ4 (1) Where P (watts) is the radiated power from a body of area A (m2) at temperature T (K). The relative humidity more than 80% always creates discomfort due to the characteristics of deliquescent of the salt in the surface of the skin [14], and100% humidity leads to muggy conditions. After a slight fall in November, it again rose to reach 75% in December. The relationship is Tt = A[1—exp(—BΔTc)] where Tt is the daily total atmospheric transmittance, ΔT is the daily range of air temperature, and A, B, and C are empirical coefficients, determined for a particular location from measured solar radiation data. The annual cycle of surface temperature lags that of incoming solar radiation by one or two months. During that period, the earth received lesser solar radiation as compared to the premonsoon period. A relationship between atmospheric transmittance and the daily range of air temperature is developed. The relationship between air temperature differences and synoptic meteorological conditions were also analyzed. The scatter plots shown in Fig. Scientific paper No. All sensors are attached with this data logger for the collection of real-time data automatically, and data logger is adjusted within half an hour resolution for one year. The relationship between mean daily wind speed and the daily thermal range at that station is reported in Fig. Hargreaves and Samani [ 9 ] suggested that solar radiation can be estimated from the above-mentioned difference between the maximum and minimum air temperatures, and introduced an empirical … The relative humidity is inversely related to the air temperature. In winter especially in January, February, November, and December, the sunshine hour was higher but the earth received the least solar radiation due to an oblique incident of the sunlight and optically thick low cloud [28]; as a result, the temperature was also low. The highest sunshine hour, clear and sunny day, made the earth surface to receive the maximum solar radiation during premonsoon. More importantly, climatic change has a great influence on the lives of people and their environments [1]. As the temperature increased, the RH gradually decreased and attained the lowest value at around 3 pm. in every site between the air temperature values collected by the two sensors especially from the morning to the afternoon. Tests on three data sets indicate that 70–90% of the variation in daily solar radiation can be accounted for by this simple model. Potential causes for this nonlinearity may be changing hydrological conditions during the different seasons and the nonlinear relationship between radiation and temperature (i.e., the Stefan‐Boltzmann law). Similarly, dew point also depends on the air temperature and relative humidity, and it is clear from Equation (1). Temperature is a measure of the thermal state of matter and represents the degree of hotness or coldness of a body. Solar radiation, ground surface and air temperatures change periodically day by day. An idealised hysteresis is shown as … Predicting mean sky transmittance of clear days (KC) The solar radiation that reaches the earth's surface on a clear day is a function of the solar constant, of the sine of the solar elevation, the relative air … It is a widely measured variable to determine the change in weather because it influences or controls other elements of the weather, such as the dew point temperature, precipitation, humidity, clouds, and atmospheric pressure [9]. However, due to the presence of the cloud in the path of the sunlight, some irregularities were found in the trend. It has a subtropical monsoon climate with summer temperatures ranging from 32°C to 35°C, winter temperatures ranging from 8°C to 15°C, and an average annual rainfall of 270 mm [20]. Even for the design of a solar energy conversion system, it requires precise knowledge of the availability of global solar radiation at the location of interest [3–5].
