1 Satellite Issues relevant to THORPEX Roger Saunders with input from Chris Velden and many others

2 Overview Current status Future Geostationary Future Polar New challenges for DA

3 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%

4 New METOP polar AMVs More coverage MODIS AMVs Triplets METOP AMVs Image pairs

5 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 1.87 m/s 1.76 m/s 14.29 deg v2010

6 ECMWF NAEDEX 2011 – ECMWF Status Report – Tony McNally MWTS / MWHS monitored since 9 th 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 17 th Feb 2011 – 8 th April 2011 See : mwts/ Status of FY3A data at ECMWF

8 Future Geostationary Satellites (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 for more details FY-4 series COMS-Next Electro-L/GOMS




12 Fifth GOES-R Conference in conjunction with 88th AMS Annual Meeting (New Orleans, LA, January 23-24 2008) COMS follow-on Satellite Program The preliminary study for meteorological mission of the follow-on satellite was finished in 2007. The feasibility study for next multi-purpose geostationary satellite is scheduled on August 2008. COMS follow-on satellite program is scheduled to begin in 2010, and to be launched in 2015. Plan to develop the high performance MI of the next generation satellite. National space program in Korea COMS (2009) COMS Next (2015) 2009 KOMPSAT 3 2009 KOMPSAT5 1999 KITSAT 3 2003 Scientific Satellite 1 2001 2005 Scientific Satellite 2 2010 Scientific Satellite 3 2006 2011 2005 KOREASAT 5 1999 KOREASAT 3 2013 Scientific Satellite 5 2015 Scientific Satellite 6 2004 KOMPSAT 2 2009 KOMPSAT4 2011 Scientific Satellite4 2012 KOMPSAT 6 2015 KOMPSAT 7 2015 KOMPSAT 8 2015 KOREASAT 6 1999 KOMPSAT 1 2009 COMS 2015 COMS Next

13 Future Geostationary Satellites (next decade) Advanced Hyperspectral Sounder Update (U.S) GeoMetWatch (GMW), a commercial entity, has responded to a request by NOAA to provide an innovative approach of 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)

14 Future Polar Satellites 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

15 Future Polar Satellites Megha Tropiques: late 2011 GPM: 2013 COSMIC-2 Meteor-3M PCW

16 Polar Communications and Weather Mission - Objectives 1. Reliable communications and navigation services in the high latitudes (North of 70º) to ensure: Security Sustainable Development Support to Northern Communities Safety of the Air and Marine Navigation Arctic Science 2. High temporal/spatial resolution meteorological data above 50º N in support of: Numerical Weather Prediction (short to medium range) Environmental monitoring, emergency response Climate monitoring 3. Space Weather Monitoring Canadian-led mission with international partnerships Canadian contribution to WMO space-based observing system data policy consistent with Resolution 40

17 Mission Concept: 2017 launch 2 satellites in highly- elliptical Molniya orbit (HEO) 12-h period 63.4 deg. Inclination Apogee: ~39,500 km Perigee: ~550 km Continuous GEO-like imagery 50N-90 N (refresh rate 15 minutes) 2-way, 24/7 high data rate communication services (up to 12 Mb/sec) Ka-band

18 High resolution models 1.5km Model Meteosat IR How to assimilate satellite data in this model ?

19 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,..)
