JMA’s GSICS and SCOPE-CM activities Presented to CGMS-43 Working Group II session, agenda item 3 (from MTSAT-2) Japan Meteorological Agency

GSICS activities SCOPE-CM activities Contents GSICS activities MTSAT-2 infrared inter-calibration MTSAT-2 visible calibration Calibration event logging SCOPE-CM activities Himawari-8/AHI radiometric calibration will be presented in the JMA-WP-09

MTSAT-2 IR GSICS Correction: currently in Demonstration Phase MTSAT-2 Infrared inter-calibration: Uncertainty evaluation of GSICS inter-calibration products MTSAT-2 IR GSICS Correction: currently in Demonstration Phase Uncertainty analysis based on Hewison (2013) vs. AIRS product Spectral mismatch is dominant vs. IASI product Good agreement w/ Hewison (2013) Systematic uncertainty of TB Preparation for Pre-operational Phase: ongoing

Collaborative work with GSICS and the University of Tokyo MTSAT-2 visible post-launch calibration Collaborative work with GSICS and the University of Tokyo Inter-calibration using Deep convective clouds (DCC) Lunar calibration with reference to the USGS ROLO model Vicarious calibration using radiative transfer (RT) simulation Consistent calibration gain (instrument degradation trend) Shaded area: 95% confidence interval of the linear regression Time series of MTSAT-2 calibration slope difference (each method is rescaled at the first calibration result)

Calibration event logging: “Landing Page” http://www.data.jma.go.jp/mscweb/en/operation/calibration_portal.html. In response to A/I 41.22: “CGMS agencies to provide working papers on current and future capabilities for calibration monitoring and event logs – CGMS-42” First step: to provide the URLs of STATIC calibration information pages for the WMO OSCAR (agreement at the 2014 GSICS annual meeting) JMA’s “landing page”: launched in February 2015 Instrument specifications Calibration events Data outages Instrument monitoring Next step (2016): to seek consensus on common naming conventions for calibration events within GSICS

GSICS activities for MTSAT-2 Summary GSICS activities for MTSAT-2 Infrared channels Uncertainty analysis of GSICS Correction w.r.t. IASI and AIRS Product: to be moved to Pre-operational Phase in 2015 Visible channel DCC inter-calibration, lunar calibration, vicarious calibration using RT simulation Good agreements in the calibration gain Calibration event log system Launch of static “landing page” SCOPE-CM activities SCM-10: Supporting the delivery of coherent AMVs from GEO and LEO satellites Reprocessing of JMA GEO data for LAGS / IOGEO project Acknowledgement We are grateful to EUMETSAT for its collaboration to helpful discussions on GSICS activities, and in particular for the uncertainty evaluation of infrared GSICS Correction, DCC inter-calibration and lunar calibration.

Thanks for your attention
