IRAS Level 1 Produc from FY-3B.

Abstract:
IRAS(InfRared Atmospheric Sounder) L1 Product is at the resolution of 17KM, and it describes the pre-processed product that after quality control, earth navigation and calibration from level 0 raw package data. It contains the following information: the geography latitude and longitude of the 56 pixels in one scan line, the land-sea mask, land cover and surface elevation , as well as solar zenith and azimuth angle, satellite zenith and azimuth angle, the raw digital counts and converted brightness temperature of 26 spectral channels, lab calibration coefficients of VIS-NIR channels and calibration coefficients of infrared channels of every lines, the dataset also includes quality flags of the processing.
