NOAA-N Prime will be the last in the series of TIROS ATN. NOAA-N' has a planned launch date of February 2009 from Vandenberg AFB, CA by a Delta II launch vehicle.
The spacecraft will continue to provide a polar-orbiting platform to support (1) environmental monitoring instruments for imaging and measuring the Earth's atmosphere, its surface, and cloud cover, including Earth radiation, atmospheric ozone, aerosol distribution, sea surface temperature, and vertical temperature and water profiles in the troposphere and stratosphere; (2) measurement of proton and electron flux at orbit altitude; (3) data collection from remote platforms; and (4) the Search and Rescue Satellite-Aided Tracking (SARSAT) system.
Additionally, NOAA-N' will be the fifth in the series of support dedicated microwave instruments for the generation of temperature, moisture, surface, and hydrological products in cloudy regions where visible and infrared (IR) instruments have decreased capability.
This spacecraft will carry an Advanced - DCS instead of the previous DCS.
