Joint Polar Satellite System (JPSS)
JPSS will ensure the continuity of satellite operations is critical to providing the data needed for weather forecasts and climate measurements. Through JPSS, NOAA will be responsible for management and procurement of the satellites and instruments associated with the afternoon orbit, which is most critical to data for weather and climate. NOAA will contract with the National Aeronautics and Space Administration to accomplish some of these tasks. The Department of Defense will be responsible for the morning orbit that is critical to national defense. NOAA will continue its successful partnership with the Air Force by managing the ground systems development and operations of the Air Force satellites.
The instruments on JPSS will be similar to those developed for the National Polar-orbiting Operational Environmental Satellite System (NPOESS). The program will continue the critical climate measurements of Earth radiation budget, total solar irradiance and ozone profiling as had been re-manifested for the NPOESS program.
The restructured JPSS will continue to address NOAA's requirements to provide global environmental data used in numerical weather prediction models for forecasts, as well as provide space weather observations, search and rescue detection capabilities, and direct read-out and data collection products and services to customers. Data and imagery obtained from the JPSS will increase timeliness, accuracy, and cost-effectiveness of public warnings and forecasts of climate and weather events, thus reducing the potential loss of human life and property and advancing the national economy.
These changes to the NPOESS program will better ensure continuity of crucial climate observations and weather data in the future. Data from instruments on JPSS will be used to continue long-term, in some cases almost 50 years, of satellite-based climate data records. These data records are unified and coherent long-term environmental observations and products that are critical to climate modelers and decision makers concerned with advancing climate change understanding, prediction, mitigation and adaptation strategies, policies and science. JPSS, with its global view, will play a vital role in continuing these climate data records.
