1 Mission: Transition unique NASA and NOAA observations and research capabilities to the operational weather community to improve short-term weather forecasts on a regional and local scale. Close collaboration with numerous WFOs and National Centers across the country SPoRT activities began in 2002, first products to AWIPS in 2003 Co-funded by NOAA since 2009 through “proving ground” activities Proven paradigm for transition of research and experimental data to “operations” Benefit: Demonstrate capability of NASA and NOAA experimental products to weather applications and societal benefit Prepare forecasters for use of data from next generation operational weather and climate satellites Overview of Short-term Prediction Research and Transition (SPoRT) Center Schematic of SPoRT R2O/O2R paradigm in test-bed environment

2 Transition of L1 GMI Data to Forecasters SPoRT has transitioned unique, real-time GPM products to NOAA’s National Hurricane Center (NHC) and Weather Prediction Center (WPC) Image above shows combination of 3 channels (89 GHz) to from an RGB composite used by forecasters to locate the center and strongest convection of tropical systems Real-time processing and image by: Frank LaFontaine (Raytheon) Dr. Robert Atkinson (USRA) Kevin McGrath (Jacobs) Hurricane Iselle as observed by the GPM Microwave Imager; screen capture from N-AWIPS Decision Support System used at NOAA NHC and WPC Red: Colder cloud tops associated with intense convection and precipitation Cyan: Non-convective clouds Used by forecasters to get a fix on the center of a tropical system

3 SPoRT obtains real-time L2 rain rate data from the GPM Processing System, formats for AWIPS II, and disseminates to forecasters via LDM Can supplement radar information in data-void regions over water and parts of western U.S. Evaluation planned for July/August with NWS WFOs to investigate operational impact of L2 observations in detecting and aiding in forecast of monsoon events Transition of L2 Rain Rate Data to Forecasters Default color curve Identifies very low rates and overall structure MRMS color curve in AWIPS II Identifies strongest precipitation clearly Images by: Frank LaFontaine (Jacobs) Geoffrey Stano (ENSCO, Inc.)

4 Transition of L3 IMERG Data to Forecasters SPoRT obtains real-time IMERG data from the GPM Processing System, formats for AWIPS II, and disseminates to forecasters via LDM Due to latency, most useful for hydrologic applications to pinpoint areas of heaviest rainfall outside of radar coverage Evaluation planned for this fall with River Forecast Center forecasters in Southern Alaska Hurricane Blanca 2100 UTC 4 June 2015 Image by: Matt Smith (UAH)

5 Integration of IMERG Product into Real-Time Land Surface Model SPoRT has completed work to integrate the GPM L3 IMERG product into a real-time, high- resolution version of the NASA Land Information System (LIS) used by SERVIR partners in East Africa for soil moisture diagnostics and local NWP model initialization IMERG (right) replaces legacy CMORPH (left) as the precipitation forcing dataset for OCONUS SPoRT-LIS IMERG will also be used by forecasters to validate regional model forecasts of precipitation Images by: Jonathan Case (ENSCO, Inc.)

6 Assimilation of GPM Products into Regional NWP SPoRT-funded project to integrate L2 GPM observations into the Gridpoint Statistical Interpolation (GSI) data assimilation system for regional NWP applications Generate packages in community GSI to assimilate GPM data (L2 GMI rainfall and DPR reflectivity) Will work with Developmental Testbed Center (DTC) to transition new assimilation modules into the community GSI for use by the weather community and potential integration into operational systems GMI L2 rain rates Control Model Simulation Oversimulation of stratiform rain over IL/IN Images by: Xuanli Li (UAH)

7 Summary As part of SPoRT’s Early Adopter Efforts, GPM observations have been transitioned to operational forecasters to address specific forecast challenges Forecast challenges addressed: – Pinpoint the center of tropical cyclones (NHC, WPC/OPC) – Supplement radar data for nowcasting precipitation in data void regions (WFOs) – More accurate accumulated precipitation observations in radar void regions for hydrologic applications (RFCs) – Forcing for international land surface models – Assimilation into regional forecast models to improve precipitation NWP forecasts As assessments unfold, SPoRT will share feedback on the operational utility of GPM products with the Science Team
