  1. The 7th meeting of the WMO/THORPEX Data Assimilation and Observing System (DAOS) Working Group Montreal, Canada, 15-16th August 2014 Update on Satellite Observations Roger Saunders and Chris Velden • Current Status • Future Geostationary • Future Polar • Update on AMVs

  2. Current Status Operational geostationary satellites – USA: GOES-13 (East), -15 (West), GOES-14 spare EUMETSAT: METEOSAT-10 (0 Deg.) & -7 (Indian Ocean); & -9 (R/S), Super R/S experiments with -8 at 2.5 min intervals for limited periods. India/ISRO: Kalpana & INSAT-3D CMA:FY-2E & F; KMA:COMS; Russia:Electro-L N1; JMA:MTSAT-2 Operational polar satellites – • Suomi-NPP data being used operationally in NWP centres (ATMS, CrIS rads) with good impacts. • METOP-A/B IASI and AMSU-A/MHS data being assimilated. GCOM-W1 (Japan) AMSR-2 proving a good replacement for AMSR-E • FY-3C (China) New MW channels at 118GHz. Monitoring shows data are good quality • ASCAT and Oceansat-2 providing scatt-derived winds. • Cosmic constellation providing GPS-RO bending angles (1 satellite died)

  4. Future Geostationary Satellites • EUMETSAT Meteosat Third Generation Imager/ Sounder • Launch in 2017/20, six satellites in series, 3 axis stabilised • High spectral IR Sounder (IRS): 700-1210 and 1600-2175cm-1 • 16 channel VIS+IR Imager (FCI): 10min scan, 2km fov • Lightning Imager (LI) • UVNS Sounder for atmospheric chemistry (Sentinel-4) • FCI and LI on first MTG sat; IRS and UVNS on second • NESDIS GOES-R Series • -R launch slipped to 2016 (West), -S launch in 2017 (East) • Advanced Imager • Lightning Mapper (some tech issues) • Space Weather instrument suite • http://www.goes-r.gov/ for more details • JMA Himawari-8 launch Sep 2014 (with ABI instruments), operational 2015; -9 launch in 2016 • CMA FY-4 series (IR Sounder, MW Sounder): 2015-2020 launches • KMA COMS-Next for geostationary environmental monitoring (~2018) • ISRO INSAT-3D operational, AMVs available • Russia HydroMet – Electro-L N2 launch in Dec 14

  5. Future Polar Satellites • ESA: Aeolus Doppler wind lidar ‘launch-ready’ in 2016. • JPSS:JPSS-1 2Q 2017 launch in PM orbit followed by JPSS-2. • GPM-core: Launched to replace aging TRMM for precip (see later) • NASA: RapidScat on ISS for scatt winds, 2014 • COSMIC-2 GPS-RO (6 low-inclination satellites approved, high-inclination awaiting funding from US side) • Canada: PCW, Status? • EUMETSAT:-Second Generation polar orbiter close to approval. • CMA: FY-3D (2015), FY-3E (2017, early morning orbit?), FY-3F (2019) • JMA: GCOM-C (2014?)

  6. GEO AMVs • NESDIS: GOES hourly AMV dissemination from May 14 • EUMETSAT: Meteosat-10 low level AMVs improved • JMA: Rapid scan AMVs expected when Himawari-8 goes operational (focused around Japan) • INSAT-3D: AMVs now available • CMA: FY-2E AMVs available • UW-CIMSS/SSEC: Reprocessing of GOES AMVs (back to 1995); Delivery in 2014 for use in reanalyses

  7. Polar AMVs Product Suite LEO-GEO • Combination of may geostationary and polar-orbiting imagers • Fills the 60-70 degree latitude gap • Quasi-operational (CIMSS) EW VIIRS • S-NPP (GOES-R algorithm) • Direct broadcast at Fairbanks (heritage algorithm) Notes: • NOAA-17 was decommissioned on 10 April 2013. AVHRR unusable since March 2010. • NOAA-16 was decommissioned on 9 June 2014. Operational MODIS • Aqua and Terra separately • Aqua and Terra combined • Direct broadcast (DB) at • McMurdo, Antarctica (Terra, Aqua) • Tromsø, Norway (Terra) • Sodankylä, Finland (Terra) • Fairbanks, Alaska (MODISdiscontinued) EW AVHRR • Global Area Coverage (GAC) for NOAA-15, -18, -19 • Metop-A, -B • HRPT (High Resolution Picture Transmission = direct readout) at • Barrow, Alaska, NOAA-18, -19 • Rothera, Antarctica, NOAA-18, -19 • Historical GAC winds, 1982-2012. Two satellites throughout most of the time series. Operational Operational Operational Complete

  9. GPM Core: First Light Images Released March 25th 2014 These are the first publically released images from GPM. The images show precipitation falling inside a March 10 extratropical cyclone over the northwest Pacific Ocean, approximately 1,000 miles east of Japan. GPM Microwave Imager (GMI) retrievals www.nasa.gov/gpm Above: Image from GMI showing rain rates across a 885 kilometer swath of an extra-tropical cyclone observed on March 10, 2014. In the northwest part of the storm, the blue areas indicate falling snow. Below: 3D view of precipitation rate inside the extra-tropical cyclone as viewed by the DPR. Vertical resolution is 250 m, horizontal resolution is ~5 km. Dual-frequency Precipitation Radar data President Obama viewing GPM data 4/24
