More Level 2 Products in CSPP Geosphere

CIMSS Scientists are adding more Level 2 GOES products (from both GOES-East and GOES-West) to Geosphere. The animation above shows Aerosol Optical Depth (AOD) (on the left) and True Color imagery (on the right). The images highlight smoke from fires near Los Angeles on 9 January 2025. The individual AOD and the True Color fields are also shown below. Aerosol Watch (link) also shows GOES-16/GOES-18 AOD fields.

AOD is computed only in regions that are presumed cloud-free. In regions where the smoke is very thick, such as in the westernmost smoke plume, AOD is not computed because the algorithm is likely misinterpreting the thick smoke as cloud.

For now, AOD and Land Surface Temperature fields are available only at the test CSPP Geosphere site. Cloud Top Height/Cloud Top Temperature are available at both urls. The CSPP Geosphere site is at https://geosphere.ssec.wisc.edu/#coordinate:0,0; .
