AWIPS images of the 1-km resolution MODIS 11.0-3.7 µm fog/stratus Brightness Temperature Difference (BTD) and the 4-km resolution GOES-12 fog/stratus BTD (above) showed the value of higher spatial resolution MODIS data for detecting power plant plumes embedded within the stratus clouds over northern Minnesota on Read More
AWIPS images of the 4-km resolution GOES-12 6.5 µm water vapor channel (above) showed a southward-propagating lee-side cold frontal gravity wave over New Mexico and Texas on 22 October 2008. This gravity wave was caused by a surface-based cold frontal boundary that was moving southward across the region.A comparison of the 1-km resolution MODIS 6.7 µm... Read More
AWIPS images of the GOES-12 and MODIS fog/stratus product around 07:30 UTC or 3:30 AM local time  (above) told two very different stories regarding the formation of river valley fog across parts of the Northeast US on 07 October 2008. In... Read More
