  1. Update: “A Multisensor 4-D Blended Water Vapor Product for Weather Forecasting” Stan Kidder John Forsythe Andy Jones

  2. Proposal • We propose to work with SPoRT to • Ingest water vapor retrievals from NASA research satellites such as Aqua and eventually NPP. The AIRS data, could be especially valuable due to the high vertical resolution. • Blend the research and operational moisture retrievals on an hourly basis into a product with layers. Currently we envision precipitable water in four layers: surface-700 hPa, 700-500 hPa, 500-300 hPa, and <300 hPa. We will also consider other layers and other moisture variables, such as relative humidity and mixing ratio. This will be a truly 4-D product: three spatial dimensions and time. • Distribute the products to forecasters in AWIPS format, train them how to use the products, and evaluate the products based on user feedback.

  3. Results So Far • http://cat.cira.colostate.edu/SPoRT/Layered/global/ • Products produced each 6 hours and made available to SPoRT via FTP: ftp://ftp.cira.colostate.edu/ftp/Kidder/SPoRT • Also, http://cat.cira.colostate.edu/SPoRT/Layered

  4. Next Steps • Work with SPoRT to get the products in AWIPS format and get them to forecasters • Add Metop data to the current AIRS-adjusted NOAA 19 data • Work on new display possibilities (see next slide) • Prepare training materials • Get and analyze forecaster feedback • Prepare publication

  5. Prototype α-channel blending product (500-300 and 850-700 RH overlaid on GOES 11 µm). • Allows visualization of connections of clouds to moisture • Forecaster comments welcome • Could pursue more rigourous time matching Dry over moist here 10/29/12 15 UTC

  6. Immediate • Forsythe $504 travel credit, must be ticketed by Nov. 17: • Possible uses: • Record training video at SPoRT for the layered water vapor product? • Travel to a west coast WFO? • “Quick Guide” completed in September, any feedback? [Anita LeRoy POC]

  9. AIRS at 0130 / 1330 LST, very close to NOAA-18/19 MIRS. Will have a data dense data period and a data sparse period. Baseline Design: Composite Results every six hours, overlaying most recent data.

  10. New alpha-weighted GOES / MIRS imagery Main project website

  11. Per Kevin: “Medford, Eureka, and Monterey have finished doing an evaluation of the WindSat instrument with SPoRT.  We will likely approach them about this product.  May consider adding WFOs such as Albuquerque, Great Falls, Boulder, or Cheyenne to the list, but unsure at this time.”

  12. CIRA Progress: • Add NOAA-18, Metop-A MIRS retrievals to product to increase spatial coverage. Should work with existing code / scripts. • Move production code to new 64 bit machine. • McIDAS files working per Frank LaFontaine. • “Quick Guide” completed in September, any feedback? [Anita LeRoy POC] • Forsythe $504 travel credit, must be ticketed by Nov. 17: • Possible uses: • Record training video at SPoRT for the layered water vapor product? • Travel to a west coast WFO?

  13. Data: Format and Flow • Ingest MIRS, AIRS and GOES retrievals in NRT. Possibly IASI also (source?). Remap to global (or CONUS?) grid. ~ 3 hour latency. • Perform blending on 4 layers • Create gridded HDFEOS / McIDAS file () • Create animations on CIRA web page. SPoRT blog entries. • Stage files for SPoRT to pull as with current CIRA TPW • Delivery formats: • HDFEOS • McIDAS* single layer / file • * McIDAS files will likely not have the “calibration block” • Automated pull of CIRA McIDAS files • Convert to desired output format (AWIPS-II?) • Process monitoring as with current CIRA TPW • Graphics available on AWIPS or AWIPS-II Baseline Design: SPoRT pulls 9 McIDAS files 4x / day.
