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

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, …

2) Visible Vicarious CalibrationGMS-5 re-calibration during pre-MODIS era

Background Calibration of past satellites data is required for climatological use GMS-5: JMA’s geostationary satellite (June 1995 to May 2003)

Problem Developed calibration technique can’t be directly applied before 2000 due to

a lack of MODIS data Solution: Use constant/climatological value for optical parametersSi
