COMS HRIT

The calibration table represents the relationships between COMS's HRIT digital count values and the temperatures of brightness for the infrared channels (IR1 to IR4) and reflectivity for the visible channel (VIS). This table is generated from the calibration table contained in the COMS HRIT dissemination data. Although the HRIT calibration table will not be altered frequently, please be aware that it is not guaranteed to remain unchanged in the future.
