VIIRS [added: and GOES!] estimates of smoke over the central United States
As noted here, CSPP software now includes the ability to show reprojected values of Aerosol Optical Depth, in this case within AWIPS. The AOD from the NOAA-20 afternoon pass on 21 July shows extensive smoke over the Plains of Canada and the northern Plains of the USA. Clean air is confined to the Upper Peninsula (UP) of Michigan. The Day Night band imagery at the same time... Read More
Polar2grid and AOD and NDVI
The Community Satellite Processing Package (CSPP) Polar2grid package is being updated and amended. Polar2grid version 3.1 (coming soon to a computer near your desk!) will include the ability to create reprojected images of Aerosol Optical Depth (AOD) and Normalized Difference Vegetation Index (NDVI). The imagery above from AWIPS shows the NOAA-20 AOD... Read More

This was captured by both GOES-18 (1-min “mesoscale”) and GOES-16 (5-min “Contiguous U.S.”) ABI imagery. What is shown is the CIMSS true color composite imagery during the day and the “dust” RGB at... Read More
