The satellites will help improve NOAA forecasts for the three to seven day time frame. The data collected from the JPSS is fed into the numerical forecast models to help improve them. The satellites will also collect atmospheric measurements, ground conditions and ocean conditions like vegetation, hurricane intensity and atmospheric moisture.
The JPSS-1 will be launch from Vandenburg Air Force Base in California pending proper flight conditions. The launch was originally scheduled for Tuesday.
This satellite is a polar orbiting satellite, which means it will orbit the earth from the one pole to the other passing the equator 14 times a day. Full coverage of the planet will then be provided twice a day.
JPSS-2 is planned to launch in 2021, and JPSS-3 and JPSS-4 are anticipated to launch in 2026 and 2031.
