Today, the nation's environmental satellites are operated by NOAA's National Environmental Satellite, Data, and Information Service in Suitland, Maryland. NOAA's operational environmental satellite system is composed of two types of satellites: geostationary operational environmental satellites (GOES) for national, regional, short-range warning and "now-casting," and polar-orbiting environmental satellites (POES) for global, long-term forecasting and environmental monitoring. Both types of satellites are necessary for providing a complete global weather monitoring system. In addition, NOAA operates satellites in the Defense Meteorological Satellite Program (DMSP), which are also polar-orbiting satellites. NESDIS also manages the processing and distribution of the millions of bits of data and images the satellites produce each day.
