Experimental GOES Turbulence Product from CIMSS

About 

The Cooperative Institute for Meteorological Satellite Studies (CIMSS) is developing a turbulence nowcasting product by applying artificial intelligence (AI) to water vapor and infrared imagery of geostationary imagers. The product estimates the probability of moderate-or-greater turbulence at commercial aircraft cruising altitude, and has validated quite well with very little bias. The product provided to AWIPS is for the 36Kft-37Kft layer.

Limitations

Experimental: This product is still being validated, and is in the experimental phase.

Clear Skies: Clear air turbulence results are not as strong.

AWIPS Data Flow: AWIPS currently only supports a single level, whereas the base product produces multiple.

AWIPS

Location: GOES-East and GOES-West By Sector → East Conus or West Conus → Derived Products →Turbulence Probability (UWSSEC)   

Color Maps: grid/lowrange enhanced

Sampling: Probability (%) of Moderate or Greater Turbulence

Quality Flags: None in AWIPS

Technique: Use in conjunction with other atmospheric fields to determine regions where Moderate or Greater Turbulence can be identified.
