VIIRS data from NOAA-20 at the CIMSS Direct Broadcast download site, above, at 1734 UTC on 2 September were used to create True Color imagery, and SST fields over the largely-clear Great Lakes. Light winds associated with persistent high pressure over the Great Lakes (below) meant suppressed vertical mixing, leading to warm water temperatures on the... Read More

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

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
