ASPB AND CIMSS WEEKLY HIGHLIGHTS FOR THE WEEK ENDING JUNE 2, 2007

IN THE PRESS:

Netcast on GOES-R: An interview on Geostationary Operational Environmental Satellite (GOES)-R for “Weather Brains”, which is a weekly online netcast, is available at http://weatherbrains.com/weatherbrains/?p=29. The section on GOES-R begins at approximately the 28th minute. (T. Schmit, E/RA2, 608-263-0291, tim.j.schmit@noaa.gov)

ITEMS FOR THE ASSISTANT ADMINISTRATOR:

Cryosphere Theme Report Approved by IGOS Partners: The report of the Integrated Global Observing Strategy (IGOS) Cryosphere Theme, led by J. Key (NESDIS/STAR), was approved at the 14th Session of the IGOS Partners held at the Intergovernmental Oceanographic Commission of UNESCO (United Nations Educational, Scientific, and Cultural Organization) in Paris on May 30. The report describes an integrated observational strategy for snow, sea ice, freshwater ice, permafrost and seasonally frozen land, glaciers, ice sheets, ice caps, and solid precipitation using satellites, airborne, and in situ measurements. The report is a collection and synthesis of input obtained from approximately 80 scientists in 17 countries primarily through workshops in Canada, Japan, and the Netherlands over the last three years. The next phase is implementation of the report's recommendations. Additional information is available at http://igos-cryosphere.org. (J. Key, E/RA2, 608-263-2605, jeff.key@noaa.gov)

Significance:
The Group on Earth Observations (GEO) Framework Document, 2004, states that the design approach for the Global Earth Observation System of Systems (GEOSS) builds on existing systems and data, as well as existing documentation describing observational needs in these areas. The IGOS Theme Reports play a primary role in this regard, as indicated in the GEO 2005 10-Year GEOSS implementation plan: "An integrated observation strategy (i.e. one that is coordinated, co-designed and shares data) is both more effective and more efficient than stand-alone strategies. This principle is exemplified by the work of the Integrated Global Observing Strategy Partnership (IGOS-P)". The IGOS Cryosphere Theme will help define an integrated, coordinated, global observing strategy for the cryosphere. The GEOSS implementation plan reference document further recommends to "Support implementation of actions called for in GCOS Implementation Plan and the relevant IGOS-P Theme Reports". Vice Admiral (Ret.) Lautenbacher is a GEO co-chair.

NOAA Mission Goal:
Understand Climate Variability and Change to Enhance Society's Ability to Plan and Respond Serve Society's Needs for Weather and Water Information Support the Nation's Commerce with Information for Safe, Efficient, and Environmentally Sound Transportation

NOAA Cross-Cutting Priorities:
Sound, Reliable State-of-the-Art Research Integrating Global Environmental Observations and Data Management

ITEMS FOR THE OFFICE DIRECTOR, STAR:

Paper on Saharan Dust Monitoring with SEVIRI Published: The manuscript entitled "Quantitative monitoring of a Saharan dust event with SEVIRI on Meteosat-8" has been published in the International Journal Of Remote Sensing. Co-authors are Jun Li (CIMSS), Peng Zhang (NSMC), Timothy J. Schmit (STAR), Johannes Schmetz (EUMETSAT), and W. Paul Menzel (STAR, now CIMSS). Reprints are available on request. (Jun Li, CIMSS, 608-262-3755, Jun.Li@ssec.wisc.edu)

ITEMS FOR THE DIVISION CHIEF, CoRP:

Near Real-Time AVHRR Polar Winds Delivered to UK Met Office: Winds over the polar regions derived from Advanced Very High Resolution Radiometer (AVHRR) Global Area Coverage (GAC, 4 km) data on NOAA-15, -16, -17, and -18 satellites is now being sent to the UK Met Office in near real-time. The Met Office requested the data for testing in their weather forecast system. The AVHRR winds are also sent to the Joint Center for Satellite Data Assimilation. Plots of the data are available at http://stratus.ssec.wisc.edu/products/rtpolarwinds. (J. Key, E/RA2, 608-263-2605, jkey@ssec.wisc.edu; D. Santek, CIMSS, 608-263-7410)

Convection Nowcasting Products Being Evaluated by NESDIS SAB: The Cooperative Institute for Meteorological Satellite Studies (CIMSS), in collaboration with the University of Alabama in Huntsville (UAH), is providing convective storm diagnostic and nowcasting products to NOAA NESDIS SAB (POC: Jay Hanna). The product suite includes mesoscale satellite winds, convective cloud mask, cloud top cooling rate, and convective initiation nowcasts. SAB analysts will be evaluating these experimental products to assess their potential value in operations. Training materials for these products have been provided to facilitate analyst understanding of product output. (K. Bedka, CIMSS, 608-265-0854, W. Feltz, CIMSS, 608-265-6283)

CIMSS Seminar on Enhanced-V Detection
: On May 29, Jason Brunner gave a Cooperative Institute for Meteorological Satellite Studies (CIMSS) seminar entitled "Toward An Objective Enhanced-V Detection Algorithm." The region of coldest cloud tops above thunderstorms sometimes has a distinct V or U shape. This pattern, often referred to as an "enhanced-V" signature, has been observed to occur during and proceeding severe weather in previous studies. An algorithm approach to objectively detect enhanced-V features with observations from the Geostationary Operational Environmental Satellite and Low Earth Orbit data was described. The main goal of this study is to develop an objective enhanced-V detection algorithm for future implementation into operations with future sensors, such as GOES-R. (M. Vasys, CIMSS)

The categories are; 0 – No Tornado, Hail, or Wind, 1 – Wind only, 2 – Hail only, 3 – Tornado only, 4 – Tornado, Hail, and Wind, 5 – Tornado and Hail only, 6 – Tornado and Wind only, 7 – Hail and Wind only.
