topics
Topics
  • Forecaster Needs
  • The GOES-R Proving Ground at the SPC
  • GOES-R Proving Ground GLM Activities
    • GLM Cases
    • Lessons Learned
  • The Future of GOES-R Proving Ground Efforts at the SPC
forecaster needs
Forecaster Needs
  • Incorporating new products into a forecaster’s routine difficult
    • Must be used constantly to gain confidence
    • Must be aware of product limitations
    • Must give information already not available
    • Usually replaces something forecasters currently use and are comfortable with
goes r proving ground at the spc
GOES-R Proving Ground at the SPC
  • Allow forecasters to do real time operational testing of GOES-R prior to launch
    • Day-1 readiness
  • Goals
    • Provide product developers with user forecaster feedback on product usefulness/performance
    • Provide forecasters with product education and tailored display
    • Aid GOES-R product integration with AWIPS-2
    • Bring a satellite perspective to the heart of radar country

Prediction of hazardous weather events from a few hours to a week in advance

Detection and prediction of hazardous weather events up to several hours in advance

goes r proving ground resources
GOES-R Proving Ground Resources
  • Dedicated training room with two N-AWIPS workstations and a PC
  • N-AWIPS and AWIPS-II workstations co-located with VORTEX-II operations
  • GOES-R Proving Ground products also available on HWT workstations
glm proxy data at the spc
GLM Proxy Data at the SPC
  • LMA data currently received from three LMA networks across country (SPoRT/NSSL)
    • Huntsville, AL; Norman, OK; Washington DC
    • Data in sources per square-km
  • LMA data re-sampled to 10-km grid to simulate GLM
    • Sources averaged over 10-km box to per square-km values… to compare to native LMA data
lessons learned
Lessons Learned
  • GLM
    • Total flash density data needed to be true GLM proxy
    • GLM proxy shows similar spatial patterns to 1-km product
    • GLM proxy signals generally weaker than 1-km product… due to averaging over 10-km box
    • GLM proxy lightning jump signals seen ~2 mins after 1-km product… again, due to averaging over 10-km box
    • Forecasters would like to see map of LMA weak areas
    • Forecaster suggestion for gridded overlay provided
    • General dataflow issues resolved (crashes, loss of data due to LMA outages)
opportunities to grow
Opportunities to Grow
  • 2010 Plans:
    • Provide select products for real-time testing within SPC operations (late 2009)
    • Invitations and announcements for 2010 Spring Experiment in January/February… experiment likely begins in late April
    • Expanded product suite possibilities
      • LMA 10-km flash density
      • LMA 10-km pixel-based trends
      • Ingest LMA data from Cape Canaveral network
    • Interact with WFOs already using LMA data operationally for training assistance (ie - HUN)
    • Provide GLM proxy data for real-time testing within SPC operations
