Seventh Annual AMS Student Conference


A comparison of GOES and MODIS imagery in operational forecasting

Jordan Gerth, CIMSS/Univ. of Wisconsin, Madison, WI

At the present time, geostationary satellites provide the bulk of satellite information used by National Weather Service (NWS) offices. While these data are consistent and reliable, and quite beneficial to weather forecasters, at times data from polar orbiters may provide a better representation of the atmosphere. The Moderate-resolution Imaging Spectroradiometer (MODIS) instruments on board the Aqua and Terra satellites provide high, one-kilometer imagery at multiple bands. For certain situations this imagery can provide more detail about the current atmosphere than that rendered by the Geostationary Operational Environmental Satellite (GOES). In turn, this enhanced detail enables operational forecasters to more accurately predict future weather patterns and phenomena. To assist forecasters in their quest for greater accuracy, the Space Science and Engineering Center (SSEC) began sending MODIS imagery and products to NWS Forecast Offices in a format that could be displayed with the Advanced Weather Information Processing System (AWIPS), the primary display package of the NWS. This presentation describes the benefits of MODIS over GOES for specific situations and offers examples of several MODIS products and their use. Uploaded Presentation File(s):
