Recent results of the Global Space-based Inter-calibration System (GSICS) inter-calibration of the GEO data with two well-calibrated hyperspectral instruments on low earth orbit (LEO) satellites, Atmospheric Infrared Sounder (AIRS) on-board the Aqua satellite and the Infrared Atmospheric Sounding Interferometer (IASI) on-board the Metop-A satellite, show that both GOES Imager and Sounder IR channels experience diurnal calibration variation around satellite midnight time, even with the implementation of MBCC at GOES Imager IR channels. The magnitude and phase of diurnal variation vary at different IR channels and change with time. This diurnal calibration variation is also observed at the 3-axis stabilized MTSAT-2 (Multifunctional Transport Satellite) operated by Japanese Meteorological Agency (JMA), and should be also available at COMS (Communication, Ocean and Meteorological Satellite) by Korean Meteorological Agency (KMA). In this study, we use the two pairs of GSICS GEO-LEO collocation data (GOES-AIRS and GOES-IASI) to develop the time-dependent correction for the GOES IR instruments, using the IASI data as reference. As GOES with AIRS and IASI collocation data cover different time in a day, the delta-correction is used to transfer the GOES-AIRS inter-calibration correction and its uncertainty to IASI standard. More detailed results will be presented in the coming meeting.
