NOAA currently operates 16 meteorological satellites in 3 separate constellations. The future NPOESS constellation will merge the two polar orbiting constellations into a single program.

GOES spacecraft

Geostationary Operational Environmental Satellites (GOES)
The GOES system maintains a continuous data stream from a two-GOES system in support of the National Weather Service requirements. These satellites send weather data and pictures that cover various sections of the United States. Current weather satellites can transmit visible or infrared photos, focus on a narrow or wide area, and maneuver in space to obtain maximum coverage. ...details

Polar Operational Environmental Satellite (POES) 
The POES satellite system offers the advantage of daily global coverage, with morning and afternoon orbits that deliver global data, for improvement of weather forecasting. The information received includes cloud cover, storm location, temperature, and heat balance in the earth's atmosphere. ...details

DMSP spacecraft
Defense Meteorological Satellite Program (DMSP)
The Defense Meteorological Satellite Program (DMSP) is a Department of Defense (DoD) program run by the Air Force Space and Missile Systems Center (SMC). The DMSP designs, builds, launches, and maintains satellites monitoring the meteorological, oceanographic, and solar-terrestrial physics environments. ...details

The National Polar-orbiting Operational Environmental Satellite System (NPOESS)
The National Polar-orbiting Operational Environmental Satellite System (NPOESS) and its managing Integrated Program Office (IPO) were established in 1994 to converge existing Air Force, NASA & NOAA polar-orbiting satellites into an integrated national program. Polar-orbiters in low-Earth orbit continue to be used to monitor global environmental conditions, collect and disseminate data related to weather, atmosphere, oceans, land and near-space environment.
