This new satellite could produce the most accurate weather predictions yet

Wednesday, 15 November 2017, 02:48:12 PM. NASA has just sent the newest NOAA weather satellite into space. The Joint Polar Satellite System-1, or JPSS-1, will give the nation a powerful new tool for predicting natural disasters.
Now that’s science we can all get behind! The Joint Polar Satellite System-1, a joint project of NASA and the National Oceanic and Atmospheric Administration, is scheduled to launch from Vandenberg Air Force Base near Lompoc, Calif., at 1:47 a.m. Wednesday. (A few previously scheduled launches have been scrubbed, however, so we’ll see what happens.) The Delta II rocket set to launch the JPSS-1 satellite is illuminated as night falls at Vandenberg Air Force Base. It is scheduled to launch early Wednesday. Kim Shiflett / NASA Once JPSS-1 makes it into orbit, its suite of five state-of-the-art instruments will collect the most high-resolution observations yet of our planet’s atmosphere, land and oceans, NOAA officials said. “These instruments are so precise that they can measure temperatures to better than one-tenth of a degree in the entire atmosphere, from the Earth’s surface up to the edge of space,” said Greg Mandt, director of the JPSS program for NOAA. The data these sensors collect will be fed into weather prediction models in almost real time. Ultimately, it will inform the seven-day forecasts you see when you hit the weather app on your phone, or turn on the morning news to decide whether or not to grab an umbrella. JPSS-1’s observations will also help forecasters predict and study major weather events and allow them to better advise communities about when they need to evacuate because of a hurricane or whether a school or workplace should call a snow day. JPSS-1 is...Read more
