Development of the MTSAT Calibration system on GSICS 1) Infrared Inter-calibration 3 Current status of MTSAT-1R/-2 IR GSICS correction  Demonstration phase, started in July 2010  Reference sensor: Metop-A/IASI and Aqua/AIRS Toward the implements to Pre-Operational phase  Additions and modifications to the netCDF conventions, Combine of RAC (Re-Analysis Correction) files To meet the requirement of bias plotting tool, already finished  Uncertainty evaluation ongoing, will be finished soon CGMS-41, Jul , 2013, Tsukuba, Japan

Development of the MTSAT Calibration system on GSICS 2) Visible Vicarious Calibration 4 Method: Comparison of observed and simulated radiance for some targets Target: Wide range of TBB in order to obtain reliable regression line  Cloud-free ocean, Cloud-free land, Liquid water cloud, DCC Radiative transfer calculation:  RSTAR (Nakajima and Tanaka [1986,1988]) Input data : Independent from GEO data  JMA Re-Analysis atmos. profiles, MODIS L1B, BRDF, Aura/OMI total column ozone, … Result of MTSAT-2 in Feb Simulated reflectivity Observed reflectivity This work have been done as part of a research program conducted in collaboration with the University of Tokyo, the visible channel calibrations of GMS and MTSAT satellites.
