GOES-16 (GOES-East) Air Mass RGB images (above) showed the signature of dry air (brighter shades of orange-red, which also indicate the presence of a lower tropopause with higher levels of stratospheric ozone within the atmospheric column) wrapping into the circulation of an anomalously-deep Hurricane Force low pressure system — which had recently...

Previous blog posts have documented how to display imagery using geo2grid, and how to create new RGB products. (Note: geo2grid v1.1 is now available at this link) This blog post will detail the steps needed to create a brightness temperature difference field. For that to occur, information must be entered into these two files within the geo2grid file structure: $GEO2GRID_HOME/libexec/python_runtime/etc/polar2grid/enhancements/abi.yaml and $GEO2GRID_HOME/libexec/python_runtime/etc/polar2grid/composites/abi.yaml....

The VIIRS (Visible/Infrared Imaging Radiometer Suite) instrument on-board NOAA-21 (launched in November 2022) is now sending data to Earth. (Here is the NOAA Satellite Tweet announcing this landmark occasion!). Direct Broadcast users can also view NOAA-21 data now; the image above was downloaded and processed using the latest Community Satellite Processing Package (CSPP) at CIMSS.... Read More
GOES-16 (GOES-East) Nighttime Microphysics RGB and Day Snow-Fog RGB images (above) showed a lake effect fog/stratus plume that was meandering slowly northward from the still-unfrozen Fort Peck Lake in northeastern Montana (just south of Glasgow) on 08 December 2022.During the hours leading up to sunrise, GOES-16 Nighttime Microphysics RGB images with an overlay of the GOES-16 Cloud Top Phase derived...
