3. METSAT Basics

4. METSAT Platforms Weather satellites provide assured real-time environmental situational awareness and detailed meteorological, oceanographic, and space environmental data Polar/Sun-synchronous – High resolution and global coverage Geosynchronous – Quick refresh and constant coverage “METSAT imagery, both from geostationary and polar- orbiting platforms, was the single most critical environmental data source during OIF. " AFW OIF Report

5. METSAT Sensors Imagers provide brightness measurements at a particular wavelength(s) of light (UV, Visible, & IR) Cloud cover, Ocean color, Ground surface imagery, Auroral imaging Sounders provide profiles of environmental parameters by measuring Infrared and Microwave radiation Vertical Temperature, moisture, and Ozone profiles In-situ monitors measure charged particles, electro- magnetic fields, and solar radiation at the spacecraft Space environment and solar emanations

25. Ionospheric Scintillation and Geomagnetic Field The Geomagnetic Field and Ionospheric Scintillation EDRs are not currently accommodated within SESS. NPOESS is working with the User community to address these EDRs: Geomagnetic Field Mitigation Strategy: Leverage high-accuracy magnetometer on SWARM Provide Comm support to SWARM via NPOESS SafetyNet Discussions between IPO and NGDC in process Ionospheric Scintillation Mitigation Strategy: Support C/NOFS “proof-of-principle” technology demonstration Invest Internal Government Study funds in alternative approaches Advocate for C/NOFS operational follow-on

26. P3I: Validated requirements that could not be met due to program constraints or technology limitations. NPOESS retained margin to add new capabilities to meet P3I needs. IPO will work to find solutions to P3I to meet User needs User Community will participate in the P3I selection process.
