摘要

太阳辐射数据对太阳能系统具有重要意义。本研究旨在估算博卡拉(Lat:28.21o N, Long. 6)水平地表日全球太阳辐射的月和季节平均值。(840°E，海拔827 m)， 2015年利用CMP6高温计测量尼泊尔。该测量结果表明，5月份的月平均太阳辐射值为20.37±5.62 MJ/m2/ day, 12月份的月平均太阳辐射值为11.37±2.38 MJ/m2/ day，年平均太阳辐射值为16.82±5.24 MJ/m2/ day。年平均清晰度指数和消光系数分别为0.51±0.14和0.53±0.31。最高气温与太阳总辐射呈正相关，负相关。

Study of Affecting Factors of Meteorological Parameters on Solar Radiation on Pokhara

Solar radiation data are of great signiﬁcance for solar energy systems. This study aimed to estimate monthly and seasonal average of daily global solar radiation on a horizontal surface in Pokhara (Lat.:28.21o N, Long.: 84o E and alt. 827 m above sea level), Nepal, by using CMP6 pyranometer in 2015. As a result of this measurement, monthly and yearly mean solar radiation values were 20.37 ±5.62 MJ/m2/ day in May, 11.37 ± 2.38 MJ/m2/ day in December and 16.82 ±5.24 MJ/m2/ day respectively. Annual average of clearness index and extinction coefficient are 0.51±0.14 and 0.53±0.31 respectively. There is positive correlation of maximum temperature and negative correlation of with global solar radiation.
