“…The total solar radiation potential will be key parameter for designing and predicting the performance of solar energy equipment and solar energy potential [4]. It has been verified that the higher the altitude greater the total solar radiation under the clear and intermediate sky conditions, but under the overcast days the solar radiation is very low in comparison with sunny days [5]. The solar radiant energy on the earth's surface is a requirement not only in the studies of climate change, environmental pollution but also in agriculture, hydrology, food industry and promotion of overall solar energy technology programs [6].…”

“…Since solar radiation reaching the Earth's surface depends on many factors which are not global character, a study of solar radiation under local weather conditions is also essential. This study is aimed at providing more information about the total solar radiation potential which will be milestone for designing and predicting the performance of solar energy equipment and solar energy potential [5].…”

The global solar radiation (GSR) and cloud transmittance factor (cf) are measured at the horizontal surface since 2009 using calibrated CMP6 Pyranometer and NILUUV Irradiance Meter at Pokhara (28.22°N, 83.32°E) which is about 800m from the sea level lying just 20km south of the Himalayas. This paper explains the daily, monthly and seasonal variation of global solar radiation and also compared with temperature and rainfall to global solar radiation. The annual average daily global solar radiation is about 4.81 kWh/m 2 /day which is sufficient to promote solar active and passive solar energy technology at sub-Himalaya terrain Pokhara and other similar geographical locations. The correlation coefficient 0.70 is found in between clearness index (K) and cloud transmittance factor (cf). This novel result can be used for location of similar meteorological and geographical characteristics at which solar data are not available.

“…Table 4 also indicates that monthly value would increase for places at higher elevation in May -September while decreasing in other months. It may be explained by the typical rainy period from May -September in Taiwan and the study in solar radiation intensity with elevation by Becker and Boyd [14]. Table 5 gives the MBE and RMSE values.…”

A simple polynomial model of the sky clearness index as predictor was proposed in this paper, for estimating the hourly solar diffuse fractions in Taiwan. The error analysis was performed through two statistical indicators, the mean bias error and the root-mean-square error. The out of database validation was also made to confirm the model generality. Next, regressions between monthly averaged conditions and geographical parameters of places (latitude, longitude, and elevation above sea level) were discussed, using the model's estimates and the updated data sets of typical solar radiation year. Based on the results, diffuse fraction maps for two observation periods were presented in 1-km resolution via an aid of linear interpolation.

“…For altitude corrections, Fig. 8 of BECKER and BOYD [7] was utilized. This graph can be used to determine the percent increase in solar radiation intensity with altitude for summer Y1 and winter Y2 conditions between altitudes X (in ft) 2000 to 10 000 ft above sea level.…”

SummaryA previously determined model [9], based on the theoretical knowledge of the physical modifications of solar energy by the atmosphere and its transformation at the surface, has been used to determine the monthly distribution of net radiation in southern California at a topoclimatic scale. Parameters utilized in the equations were cloud cover, cloud type, surface albedo, precipitable water vapor, surface temperature, slope angle, slope orientation, elevation, and urban smog. A remarkable contrast was found between relatively high net radiation values for the littoral and coastal mountains and those of the lower values of the arid eastern parts of southern California.
