Accomplishments with image “products” from the GOES Sounder and Imager

- GOES montage assembled for Hurricane Isabel (Sep 2003)

- Animation of layered precipitable water (PW) Sounder SFOV derived product imagery (DPI) added (Dec 2003)

- CIMSS GOES Realtime Page transferred to new CIMSS web server (Jan 2004)

- CIMSS GOES Realtime Page transitioned to solely SFOV Sounder products (from “vern), following loss of “suomi” (Mar 2004)

- Observed GOES imagery compared to CRAS forecast imagery (ongoing) [REDOGS.BAT, COMPGOVCF.BAT, makgovcf.scr, …]

Fledgling effort to improve the GOES Sounder retrievals back in early 2003, with GOES retrieval “directions” meetings (resulting from dissatisfaction with some of the routine DPI during IHOP), has culminated in a renewed focus to continue work on the current GOES Sounders, in the GOES Retrieval Science (GRS) team, dynamically led by Jun Li. Development is underway with various modifications, considering time continuity constraints, inverted cone filtering, model independent first-guess, and surface emissivity.

Total PW

High layer PW

Mid layer PW

Low layer PW

Note how ovals of relative

maximum PW, over US, shift with height.

Note that layered scale (0-30mm) is half that of total

Mid layer PW pattern seems closest to that of total; high layer PW is most distinct.

Example of real-time GOES Sounder Derived Product Imagery Focused on Wisconsin

GOES (40-50mm+) markedly moister than first-guess

GOES (<40mm) evidently drier than

first-guess

(Shouldn’t such differences impact forecasts ?)

GOES total precipitable water (TPW) DPI at

1700 UTC on 25 Aug 2003

Fundamental CIMSS research: striving to make quality real-time GOES Sounder radiance observations into practical useful information for weather forecasting

Atmospheric continuity and evolution are clearly evident

in multi-spectral

animation.

Where will clouds be? Comparison between

observed imagery (bottom) and forecast imagery (top) builds confidence in how

well the CRAS model is assimilating

retrieved GOES Sounder cloud and

moisture information.

Where will forecast (GFS) moisture need to be modified, monitoring trends, to provide a

better forecast for convection (as across Texas)? Differences between retrieved

GOES Sounder TPW and the GFS forecast values are plotted over the GOES TPW

Derived Product Imagery (DPI).

Accomplishments with advocacy for GOES products

- Completed publication process (following Bill Raymond’s death in Feb 2003) for:Raymond, W.H., G.S. Wade, and T.H. Zapotocny, 2004: Assimilating GOES Brightness Temperatures. Part 1: Upper Tropospheric Moisture. J. Appl. Meteor., 43, 17-27. _ , 2004: Assimilating GOES Brightness Temperatures. Part 2: Assigning Water Vapor Wind Heights Directly from Weighting Functions. J. Appl. Meteor., 43, 1200-12.

- Detailed critiques of Beta tests of VISIT training modules (1. Interactive cloud height algorithm and GOES Sounder point retrievals in AWIPS 2. Forecasting convective downburst potential using GOES Sounder derived products)

- Trips to southern Wisconsin NWS Office (MKX) in Sullivan: Sep 2003 (with T. Mostek (COMET) and CIMSS contingent); Mar 2004 (with S. Bachmeier for “shadowing” N. Johnston and IFPS processing experience)

- Report from Aug 2003 Workshop on Satellite Data Application and Information Extraction (WSDAIE) (Dec 2003)

- Planning for “WSDAIE-2” at Oct 2004 National Weather Association (NWA) Annual Meeting for workshop on “towards better utilization of satellite information” (ongoing)

- Provision of CIMSS GOES DPI (+?) to feed (1) regional AWIPS (NWS), (2) in-house AWIPS, and (3) IDV users (UNIDATA). AWIPS needs NetCDF format. CIMSS and SSEC Data Center working on ingest of new NOAAPORT DVB (direct video broadcast) signal with help from UNIDATA. (ongoing)

Adjusting a model field with GOES observations

The demonstrated assimilation procedure modifies only the moisture field in

physical space (in contrast to radiance space). The numerical optimization of the

differences for channel 3 brightness temperatures (water vapor at 6.7 um),

between the forecast initial conditions (by a forward radiative model) and the

observed GOES values, is incorporated directly into the CIMSS Regional

Assimilation System (CRAS) forecast model. The partitioning of changes made to the model moisture field, in physical

space, is directly proportional to the observational weighting functions.
