Will we be able to use this model for cp.net program?

Major weather forecasting advancement revealed:
NASA and the National Oceanic and Atmospheric administration today outlined research that has helped to improve the accuracy of medium-range weather forecasts in the Northern Hemisphere.


NASA\'s Atmospheric Infrared Sounder instrument is able to peel back cloud cover to reveal 3-D data of a storm\'s water vapor content, information that can be used to improve weather forecast models.

NASA and NOAA scientists at the Joint Center for Satellite Data Assimilation in Camp Springs, Md., came up with procedures to improve forecasting accuracy. The scientists worked with experimental data from the Atmospheric Infrared Sounder instrument on NASA\'s Aqua satellite.

They found incorporating the instrument\'s data into numerical weather prediction models improves the accuracy range of experimental six-day Northern Hemisphere weather forecasts by up to six hours, a four-percent increase. The Atmospheric Infrared Sounder is a high-spectral resolution infrared instrument that takes 3-D pictures of atmospheric temperatures, water vapor and trace gases.

The instrument data have been officially incorporated into the National Oceanic and Atmospheric Administration¹s National Weather Service operational weather forecasts.

\"NASA is assisting the world\'s weather prediction agencies by providing very detailed, accurate observations of key atmospheric variables that interact to shape our weather and climate,\" said Dr. Mary Cleave, associate administrator for NASA\'s Science Mission Directorate. \"The forecast improvement accomplishment alone makes the AIRS project well worth the American taxpayers\' investment.\"

\"This AIRS instrument has provided the most significant increase in forecast improvement in this time range of any other single instrument,² said retired Navy Vice Adm. Conrad C. Lautenbacher, Jr., Ph.D., under secretary of commerce for oceans and atmosphere and National Oceanic and Atmospheric Administration administrator.

\"Climate and weather forecasts are dependent upon our understanding current global ocean and atmosphere conditions,² added Lautenbacher. ³If we want to be able to predict what the weather will be like in the future, we must adequately define the global conditions today. Satellite data, like AIRS provides, is a vital link for NOAA to take the pulse of the planet continuously.\"

\"A four-percent increase in forecast accuracy at five or six days normally takes several years to achieve,\" said Joint Center for Satellite Data Assimilation Director Dr. John LeMarshall. \"This is a major advancement, and it is only the start of what we may see as much more data from this instrument are incorporated into operational forecast models at the National Oceanic and Atmospheric Administration¹s Environmental Modeling Center.\"

The European Center for Medium-Range Weather Forecasts began incorporating data from the Atmospheric Infrared Sounder into their operational forecasts in October 2003. The center reported an improvement in forecast accuracy of eight hours in Southern Hemisphere five-day forecasts.

The Atmospheric Infrared Sounder instrument is the result of more than 30 years of atmospheric research and is led by Dr. Moustafa Chahine of NASA¹s Jet Propulsion Laboratory, Pasadena, Calif. It is the first in a series of advanced infrared sounders that will provide accurate, detailed atmospheric temperature and moisture observations for weather and climate applications.

The Joint Center for Satellite Data Assimilation is operated by the National Oceanic and Atmospheric Administration, NASA and the U.S. Air Force and Navy. The goals of the center are to accelerate the use of observations from Earth-orbiting satellites to improve weather and climate forecasts, and to increase the accuracy of climate data sets.
