More detailed atmospheric information is being produced at the NOAA Environmental Modeling Center, allowing public and private meteorologists to forecast with increasing accuracy.

The announcement follows major upgrades to the NOAA Global Forecast System, which is the primary model used to forecast weather patterns around the globe. The GFS is used in a variety of NOAA National Weather Service forecasts, including hurricanes, heavy precipitation, drought, snowstorms, icing and aviation. Now, the GFS incorporates improved physics of the atmosphere, a clearer representation of the Earth's terrain, enhanced satellite data from NASA's Atmospheric InfraRed Sounder, as well as other technical changes.
"Our nation will have longer-ranging alerts and forecasts through these improvements to the current system thanks to its more specific and higher resolution output," said retired Navy Vice Admiral Conrad C. Lautenbacher, Jr., Ph.D., undersecretary of commerce for oceans and atmosphere and NOAA administrator. "These significant developments will have a huge impact on the economy and citizens’ quality of life locally and nationally."
The GFS produces forecasts of wind, temperature, humidity and air pressure for the atmosphere up to 35 miles above the Earth for one to 15 days. NOAA is currently working on additional ways to extract and use even more of NASA's AIRS data in NOAA's operational weather and climate forecast models.
Well, as long as we keep Santorum's filthy paws off of NOAA/NWS.
