Transition of AIRS Soundings to the National Weather Service

Brad Zavodsky SPoRT/University of Alabama in Huntsville

AIRS Science Team Meeting, Pasadena, CA April 16, 2008

NASA’s Short Term Prediction Research and Transition (SPoRT) Center

Mission: Apply NASA measurement systems and unique Earth science research to improve the accuracy of short-term (0-24 hr) weather prediction at the regional and local scale (http://weather.msfc.nasa.gov/sport/)

  • Test-bed for rapid prototyping of new products
  • Development of new products is end-user driven
  • Transition research capabilities / products to operations
    • real-time (RT) MODIS, GOES, and AMSR-E data and selected products to National Weather Service (NWS) weather forecast offices (WFOs) and private entities (e.g.Worldwinds, Inc., The Weather Channel)
  • Observations from AIRS can provide benefits to operations:
    • if forecasters learn the strengths and limitations of the data
    • if the data is available in forecasters’ native system
slide3

AIRS Use in Operational Forecasting

  • AIRS retrieves asynoptic soundings over a large area that supplement traditional upper air soundings
  • AIRS soundings may be beneficial to predicting atmospheric stability in the pre-convective environment for improved severe weather forecasting
  • Use direct broadcast data (U. Wisc.) to avoid lag of 0.5-1.5 hours, which is critical time for operational forecasting
  • AIRS Data for operational forecasting:
    • L2 AIRS temperature and moisture profile product
    • Assimilation of AIRS profiles and radiances into regional forecast models
    • L1B AIRS imagery and products

L2 Temperature and Moisture Profile Product

AWIPS GOES sounder (green) locations overlaying IR image

  • Profiles configured for view in native NWS display system (AWIPS)
  • Each golfball is represented by a grid box within AWIPS (green)
  • Forecasters move interactive points (salmon) to view profiles
  • AIRS profile locations overlain with satellite imagery to determine best soundings

Let’s look at an example Skew-T in AWIPS

slide5

L2 Temperature and Moisture Profile Product (cnt’d)

AWIPS GOES (green) display w/ example AIRS (red) overlain

  • AIRS sounding overlain with other upper air observations
  • Display multiple soundings to show frontal positions
  • Profile information (e.g. stability, PWV) calculated by system and displayed for each observation

Training Forecasters

  • Science Sharing Sessions with Huntsville NWS WFO
    • face-to-face interaction with forecasters
  • Articulate training module for other offices in Southern Region
    • animated Powerpoint slides with voice over
  • SPoRT’s NRT sounding tool
    • soundings currently available to forecasters used for comparison to AIRS
slide7

Summary

  • SPoRT is transitioning direct broadcast AIRS profiles to the National Weather Service
    • provide asynoptic soundings over a large area
    • add atmospheric stability data in pre-convective environment
    • monitor moisture changes
  • AIRS profiles will be inserted directly into AWIPS allowing forecasters to display them alongside other available data
  • Using face-to-face presentations, remote presentations, and NRT web tool to train forecasters how to best use this new AIRS data set
