Applications Library :: Air Mass RGB Applications: Diagnosing Potential Vorticity During Strong Diurnal Heating

Description: The Air Mass RGB can sometimes show large “red” regions that typically indicate the location of a jet streak and associated vorticity, but diurnal heating of the land surface can also result in this color and hence, a false signature. Title: Application for Large-Scale Event in Southwest U.S. Date of Event: February 13, 2017 Region: CONUS West/Southwest, Australia Author: Angela

Applications Library :: Dust RGB: Application for Large-Scale Event in Southwest U.S.

Description: Prior to having the Dust RGB from a geostationary platform, the NWS Albuquerque forecasters applied the MODIS and VIIRS Dust RGB product, derived from EUMETSTAT’s ‘best practices’ recipe. The Dust RGB is applied to monitor the extent and movement of the dust plume, even at night, and then impact aviation forecasts. Title: Application for Large-Scale Event in Southwest U.S.

Applications Library :: Dust RGB Applications: Dryline Analysis in U.S. Southwest

Description: The Dust RGB is able to distinguish many features beyond atmospheric dust plies. One of the secondary applications is the analysis of dry lines. This item examines the use of the Dust RGB from GOES-16 compared to other single-channel imagery to identify dry lines that lead to convection and precipitation. Title: Dryline Analysis in U.S. Southwest Date of Event:

Applications Library :: True Color RGB, Burn Scar Identification (Texas, Oklahoma, 7 March 2017)

Warm, dry conditions and strong winds caused wildfires to erupt in the Texas and Oklahoma panhandles, burning hundreds of thousands of acres.  Active fires can be monitored using True Color RGB and Visible (0.64 µm) imagery to analyze the location and extent of the event.

Applications Library :: Day Convection RGB, Damaging Storms Across Georgia on 3 Apr 2017

The Day Convection RGB provides the ability to identify strong, convective updrafts via small ice particle detection at cloud tops as is seen in this example of severe storm activity in central Georgia. The capacity to detect microphysical characteristics of convective clouds improves forecasting of the storm strength and stage.

Applications Library :: True Color RGB, Wildfire Smoke Monitoring (W. Texas, 7 March 2017)

Smoke moving south from the north Texas and Oklahoma fires were impacting visibilities for TAF sites in west Texas, as well as creating a public health hazard. By using True Color RGB imagery, forecasters can monitor the spatial extent and movement of the smoke and determine where the smoke is likely to clear.
