AWIPS images of the 1-km resolution MODIS 0.65 µm visible channel data (above) showed a hint of a few aircraft contrails over the Southwestern US at 18:03 and 21:22 UTC on 16 March 2010. However, note that many more contrails were apparent on the corresponding MODIS 1.4 µm near-IR “cirrus detection channel”... Read More
AWIPS images of the 1-km resolution MODIS Sea Surface Temperature (SST) product (above) showed some intricate details in the SST structure of the warm Loop Current in the eastern Gulf of Mexico on 13 March 2010. Note the “swirl” of slightly cooler SST values (lighter orange colors) in the northern portion of the... Read More
EUMETSAT Metetosat-9 10.8 µm IR images (above; also available as a QuickTime movie) showed the evolution of a disturbance that had all the appearances of being another example of a rather rare event: a subtropical cyclone in the South Atlantic Ocean (off the southeast coast of Brazil) during the 09 March...

Andy Heidinger (NOAA/NESDIS/Advanced Satellite Products Branch) pointed out a very long and thin cloud feature, which can be seen near the center of the false color Red/Green/Blue (RGB) image created using AVHRR imagery (above). In this particular RGB image, low clouds appear dark blue, while cirrus clouds are white. The cloud feature of... Read More
