The Suomi National Polar-orbiting Partnership (NPP) program is a joint effort between NASA, the National Oceanic and Atmospheric Administration (NOAA), and the Department of Defense. The Suomi-NPP satellite was launched in 2011 and provides critical data for weather forecasting, climate monitoring, and environmental research. The satellite’s instruments capture a wide range of data including atmospheric temperature and moisture, land and ocean surface temperature, and total and spectral solar irradiance. The Suomi-NPP program is an important tool for understanding and predicting changes in Earth’s climate and ecosystem.
