Abstract—

This work considers the current status of meteorological stations of actinometric observations in Uzbekistan. The data obtained from six modern ground-based meteorological stations in Uzbekistan are compared with the satellite observations and reanalysis data from NASA POWER, ERA5, and SARAH-E. It is shown that the comparative deviations of the data of NASA POWER from the ground monthly amounts of solar radiation on the horizontal surface for most regions of Uzbekistan from April to September do not exceed 8%, which is quite acceptable for the design of solar power plants. The comparative deviations of the data of ERA5 and SARAH1E for the same period of the year do not exceed 8 to 12%. According to the results of the calculation studies on verifying global horizontal solar radiation using the three aforementioned databases, these can be used in engineering calculations. When performing calculation studies, one can select any base depending on the required information, i.e. daily or hourly solar radiation values.

乌兹别克斯坦共和国太阳能光伏植物资源指标。第2部分。验证乌兹别克斯坦状况的卫星光化学计量和再分析数据

摘要-

这项工作考虑了乌兹别克斯坦的光化学计量气象站的现状。从乌兹别克斯坦的六个现代地面气象站获得的数据与来自NASA POWER，ERA5和SARAH-E的卫星观测和再分析数据进行了比较。结果表明，在4月至9月的大部分时间，乌兹别克斯坦大部分地区NASA POWER数据与地面月地面太阳辐射量的比较偏差均不超过8％，这对于设计太阳能来说是可以接受的植物。同期的ERA5和SARAH1E数据的比较偏差不超过8％至12％。根据使用上述三个数据库验证全球水平太阳辐射的计算研究结果，这些可以用于工程计算中。在进行计算研究时，可以根据所需信息（即每日或每小时的太阳辐射值）选择任何基准。
