Yes! The U.S. launched a new weather satellite on Thursday March 1st.
This is the second in a series of four next-generation weather satellites now in orbit 22,300 miles above the Earth. It will reach its final orbit location in approximately two weeks, and will be referred to as GOES-17 (Geostationary Operational Environmental Satellite, number 17).
It will orbit above the western part of North America and will provide faster, more accurate observations for tracking wildfires, fog and storm systems and hazards that threaten the western United States, including Hawaii and Alaska.
Satellite data help forecast the weather in two ways: Expert forecasters interpret the images, and numerical weather-prediction models assimilate observations. Image analysis plays an important role in short-term forecasts, those that predict the weather one to three hours into the future. Numerical weather predictions are more useful in 12-hour to three-day forecasts.
While weather forecasters routinely analyze current satellite observations, most data never reaches forecasters’ eyes. Most satellite observations go directly into numerical weather-prediction models. In fact, today’s weather forecast models rely on satellite data more than any other weather observation. These data include the vertical distribution of temperature and humidity, cloud distributions, land and sea surface temperatures, location of volcanic ash and wind speeds and directions.
Today, more than 120 U.S. space-based instruments observe our planet.
Other nations have just as much interest in observing weather from space as does the U.S. International collaborations organized through the World Meteorological Organization offer a powerful way to understand weather on a global scale.
