The thermal infrared channels was in-flight calibrated by using surface temperature in Qinhai lake measured by auto buoy and atmospheric profile of NCEP reanalyzed data in Qinhai lake. The calibration results by using this method are consistent with those by using normal experiment method, which can in-flight calibrate the thermal infrared channels of satellite sensors constantly.
