• Conducted July 19 August 30, 1999

• Heightened the forecasters situational awareness
  to potential watch/warnings scenarios
• Led to the issuance of improved forecast products
  in over 79 of all active weather situations
• GOES sounder products especially useful for
• Locating maximum instability atmospheric
  moisture axes prior to convective development
• Observing temporal changes in stability
  moisture
• Judging the validity of NWP forecasts

GOES Products Distributed Over AWIPSSignificant
milestone for NOAA!!

• All NOAA/NWS offices now or will soon have
  digital access to several GOES products and
  sounder imagery
• NWS field forecasters can use these data in their
  daily forecast preparations
• AWIPS workstations allow forecasters to easily
  integrate GOES wind products with other data
  sources (model output, ACARS, rawinsondes, etc)

SFOV Products

• Experimental production and validation at FPDT
  CIMSS (point image)
• Increased horizontal coverage offers exciting
  possibilities for enhanced use of product in
  mesoscale forecasting
• Improved depiction of gradients in retrieved
  products (PW, LI, etc)
• Focus attention to localized areas of interest
  (instability)

12
Single FOV soundings (10km resolution) offer
significantly improved coverage. Derived SFOV
quantities, such as atmospheric stability, can be
plotted over imagery or can be placed in image
format and used by NWS for severe storm
forecasting

Experimental Watch Area SFOV Sounder Products

• Use NWS FOS text product to find severe Wx watch
  boxes define corner points
• Subsect sounder image about watch area(s)
• Quickly generate SFOV sounder GOES products
  (stability) and disseminate ASAP
• Reduced latency

• Product latency
• Key factor for increasing the utility of the
  sounder products
• IHOP offered us an opportunity to demonstrate
  these products could be produced with reduced
  latency
• SFOV product processing requires significantly
  more processing
• stream-lined software
• software ported to new H/W
• FPDT successfully delivered GOES-8 GOES-11 SFOV
  PW and cloud products to FSL for use in the Local
  Analysis Prediction System (LAPS)

The remainder of the presentation will on
focus initial results from the retrospective test
designed to quantify the forecast impact from the
special rapid-scan satellite winds. In this
test, two parallel sets of 1-h cycled RUC
forecasts were produced for a meteorologically
active period. The first experiment utilized all
conventional observations (rawinsonde, 404 and
915 MHz profiler, RASS, VAD, ACARS, and surface
reports), while the second experiment,
supplemented the conventional observations with
the rapid-scan satellite winds. Initial
results from the retrospective test indicate that
inclusion of the rapid-scan satellite wind
observations improved short-range (0-12 h) wind
predictions by up to 10 for this case.
