Fog/stratus product: MODIS vs GOES

Comparisons of the 1-km resolution MODIS fog/stratus product with the 4-km resolution GOES fog/stratus product help to underscore the improved ability to detect subtle features using higher spatial resolution satellite data. AWIPS images of the MODIS and GOES-11 fog/stratus products (plus topography) covering the Monterey and Fresno, California regions on... Read More

Satellite signatures of the Mississippi Alluvial Valley

AWIPS images of the MODIS visible channel along with the Normalized Difference Vegetation Index (NDVI) and Land Surface Temperature (LST) products (above) depicted the areal extent of the Mississippi Alluvial Valley (MAV) on 12 May 2008. This physiographic feature represents the historical flood plain of the lower Mississippi River, which stretches from... Read More

Classic enhanced-V and anvil plume signatures

The severe thunderstorm that was producing a significant long-track tornado (approximately 75 miles long, and around 1 mile wide at times) across parts of northeastern Oklahoma and southwestern Missouri on 10 May 2008 exhibited a classic “enhanced-v” signature on both GOES-12 and NOAA-16 IR imagery. The coldest cloud top brightness temperature values... Read More
