Satellite Issues relevant to THORPEX Roger Saunders with input from Chris Velden and many others
Overview • Current status • Future Geostationary • Future Polar • New challenges for DA
Current Status • All geostationary satellites operational GOES 11/13 &12 to S. America, JMA switched from MTSAT-1R to -2 • New Geostationary satellites COMS (1 Vis, 4IR channels) and GOMS-2 (3 Vis, 7IR channels) looking good • Indian Oceansat-2 scatterometer looks promising to replace Quikscat. • Chinese FY-3 series providing good MW sounder data for NWP. ECMWF ready to assimilate MWHS radiances. • NPP and METOP-B to launch 2011/12 • Extension of EOS (~2015) and ENVISAT (~2014) • McMurdo is coming online will reduce data delay by 50%

ISRO L2B vs ECMWF • SDs of differences given • Outliers reason for degradation w.r.t. OWDP ? • Bias at low speeds • Vector RMS difference of 2.6 m/s (>2 m/s) 1.56 m/s 14.29 deg 1.87 m/s 1.76 m/s v2010
Status of FY3A data at ECMWF • MWTS / MWHS monitored since 9th Nov 2010. • Problems with data stability and spikes continue (but recent steps to ground processing are an improvement) • We will activate the data in ECMWF operations when the data is reliable and stable MEAN FG_DEP STD FG_DEP See : http://www.ecmwf.int/products/forecasts/d/charts/monitoring/satellite/FY/mwts/ 17th Feb 2011 – 8th April 2011
Future GeostationarySatellites (next decade) • Meteosat Third Generation Imager and Sounder • Launch in 2016/18, six satellites in series, 3 axis stabilised • High spectral IR Sounder 700-1210 and 1600-2175cm-1 • 16 channel VIS+IR Imager (10min scan, 2km fov) • Lightning Imager • UVNS Sounder for atmospheric chemistry (Sentinel-4) • GOES-R Series • -R launch in 2015, -S launch in 2017 • Advanced imager • Lightning mapper • Space Weather instrument suite • http://www.goes-r.gov/ for more details • FY-4 series • COMS-Next • Electro-L/GOMS

Future GeostationarySatellites (next decade) • Advanced Hyperspectral Sounder Update (U.S) • GeoMetWatch (GMW), a commercial entity, has responded to a request by NOAA to provide an innovative approachof co-hosting an operational, hyper-spectral Geo sounder on one of the many existing commercial satellite systems. • Fee-for-Service, 24/7 operational sounder data • The GMW commercial sounder would restore most of the capabilities of the previously proposed HES. • The spectral resolution of the GMW sounder is currently proposed to be the same as the GIFTS spec and comparable with 2 of the original HES bands trade studies. • Proposed coverage implementation: 2014-2020 (6 operational sounders, global coverage)
Future PolarSatellites • ESA ADM delay to 2013 due to laser reliability • Japanese GCOM-W will provide AMSR continuity • JPSS (replaces NPOESS) • NPP late 2011 • First JPSS 2017 launch in PM orbit • VIIRS, CrIS, ATMS, OMPS and CERES/ERBS • DWSS to replace DMSP ~ 2018 with MIS • Post EPS • Under definition studies • Base payload: Vir/IR imager, IR sounder, MW sounder, scatterometer, UVNS sounder

Main messages for THORPEX • Extended life of some research satellites helps to mitigate losses elsewhere • Reduced thinning of AMSU-A shown to beneficial • Hyperspectral sounder in GEO orbit now approved by Europe on MTG, assimilation of PCs new area of research • Contribution to GOS by nations increasing (e.g. FY-3, Oceansat-2) to fill future gaps in GOS • Further delay in ESA wind lidar • Challenge of assimilation of satellite data in high resolution local area models and extend use of advanced IR sounders (cloudy rads, use PCs,..)
