A new generation American meteorological satellite has been launched to scrutinize the Earth's climate. The first of a series of four satellites.

It was supposed to be launched at the beginning of the month. After several postponements, including due to weather conditions, the Joint Polar Satellite System-1 (JPSS-1) satellite finally took off on Saturday from US Vandenberg Air Force Base in California.
This satellite is the first in a series of four meteorological satellites that will be deployed in polar orbit by the National Oceanic and Atmospheric Administration (NOAA), and thus with the participation of the US Space Agency .
When it reaches its final orbit, JPSS-1 will be renamed NOAA-20. After a verification and validation period of three months, the satellite will become operational. With five instruments, he will scan the entire planet twice a day.
These instruments will collect data on land and ocean surface temperatures, vegetation, clouds, precipitation, snow and ice cover, fires, atmospheric temperature, water vapor and ozone.

The data will be used to improve US weather forecasts to seven days (instead of three days), for example tracking hurricanes, and helping to recognize weather patterns that may affect weather conditions.
"The instruments are so precise that they can measure temperature to more than one-tenth of a degree from the surface of the planet to the space boundary," says Greg Mandt of NOAA.
