AWIPS images of 1-km resolution POES AVHRR visible channel 1 (0.63 µm) and channel 2 (0.86 µm) along with IR channel 4 (10.8 µm) data (below) showed Hurricane Earl moving northwestward, just to the northeast of the Bahamas, on 01 September 2010. Earl’s intensity decreased from a Category 4 to... Read More

Evidence of a large region of mid-tropospheric dry air on AWIPS images of GOES-13 6.5 µm “water vapor channel” data (above; also available as a QuickTime movie) in tandem with an increase in Read More
