Surface solar irradiance (SSI) is one of the products of FY-4A L2 quantitative inversion. It covers a full disk without projection, with a spatial resolution of 4km and a temporal resolution of 15min (there are 40 observation times in the whole day since 20180921, except for the observation of each hour, there is one observation every 3hr before and after the hour）, and the spectral range is 0.2µ m～5.0 µ m. The output elements of the product include total irradiance, direct irradiance on horizontal plane and scattered irradiance, the effective measurement ranges between 0-1500 w / m2. The qualitative improvement of FY-4A SSI products in coverage, spatial resolution, time continuity, output elements and other aspects makes it possible to further carry out its fine application in solar energy, agriculture, ecology, transportation and other professional meteorological services. The current research results show that the overall correlation of FY-4A SSI product in China is more than 0.75 compared with ground-based observation, which can be used for solar energy resource assessment in China.

File naming and required software

Naming method: the ground solar radiation products are stored in NC format, and the naming method is "FY-4Asub_SSI_QZGY_075106_024042.yyyymmddhhMMSS ", where yyyy is the year, mm is the month, dd is the day, HH is the hour, MM is the minute, SS is the second, and the time zone is universal time. This file represents the ground solar radiation at that time.
Data reading mode: hdfview, panoply and other software can be used to read
