Overview

•Current status

•Future Geostationary

•Future Polar

•New challenges for DA

Current Status• All geostationary satellites operational GOES 11/13 &12 to S.

• 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%

•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

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.

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 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)

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

Future PolarSatellites

• Megha Tropiques: late 2011

• GPM: 2013

• COSMIC-2

• Meteor-3M

• PCW

Polar Communications and Weather Mission - Objectives

1. Reliable communications and navigation servicesin 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 meteorologicaldata 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

How to assimilatesatellite data in this model ?

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,..)
