GOES: NOAA\u2019s geostationary weather satellites
Answer: NOAA's Geostationary Operational Environmental Satellites (GOES) orbit 22,236 miles above Earth's equator, at speeds equal to Earth's rotation. That lets each one stay over the same region and provide continuous coverage of it over time.
What GOES-R provides
The GOES-R Series is the Western Hemisphere's most sophisticated weather-observing and environmental-monitoring system. It provides advanced imagery and atmospheric measurements, real-time mapping of lightning activity, and monitoring of space weather. GOES-R satellites are designated with a letter during development and renamed with a number after reaching geostationary orbit.
Why geostationary matters for weather
Because GOES satellites stay above a fixed spot on the surface, they keep a constant vigil for the atmospheric "triggers" for severe weather conditions such as tornadoes, flash floods, hail storms, and hurricanes. When these conditions develop the satellites can monitor storm development and track their movements.
Other uses
- GOES imagery is used to estimate rainfall during thunderstorms and hurricanes for flash flood warnings.
- It also estimates snowfall accumulations, which helps meteorologists issue winter storm warnings and spring snow melt advisories.
- Satellite sensors also detect ice fields.
Altitude figures
The OSPO page puts the geosynchronous plane at about 35,800 km (22,300 miles) above the Earth.
