UW-CIMSS Advanced Satellite Aviation-weather Product Overview W. Feltz and ASAP Team 8 June 2005 http://cimss.ssec.wisc.edu/asap/
ASAP Overview What is ASAP? Why is this being presented at the MURI workshop?? Aviation Satellite Research Products and Collaborations Data access and references
Advanced Satellite Aviation- weather Products (ASAP): Primary Goal: Develop and Provide High Resolution (Temporally and Spatially) Weather Products in Near Real-time to Improve Avaition Safety Who: A Collaborative Research Venture between NASA & FAA, NCAR, SSEC/CIMSS, & U-Alabama Huntsville, Funded by NASA to aid FAA in satellite data infusion into Aviation Meteorological Products How: Develop applications to support detection of aviation hazards (visibility, turbulence, volcanic ash, convection, etc) using current and future satellite based instrumentation -> FAA PDT’s
What NCAR Product Development Teams might Benefit from Satellite Data? The Product Development Teams (PDT)s are: In-Flight Icing Aviation Forecasts Quality Assessment Turbulence Winter Weather Research Convective Weather National Ceiling and Visibility NEXRAD Enhancements Juneau Terrain-Induced Turbulence Model Development and Enhancement Oceanic Weather
Why ASAP Overview Presented Here? ASAP has provided a “head start” towards Broadband/Narrowband IR derived interest fields used for detection of aviation hazards. The FAA PDT’s had been under utilizing satellite information. ASAP’s mission to tailor satellite products for use in PDT “smart algorithms”. MURI has provided the funding for basic research to improve our hyperspectral resolution, and we are looking to use these data sets to simulate future geostationary hyperspectral resolution derived aviation weather products relevant to FAA and Navy safety concerns.

The product is compared in real time to pilot reports of turbulence in a web-based java animation.
GOES Satellite Winds (Blue) Winds Rejected by Model (Yellow) Winds were rejected due to slower model backing winds. These diagonostic winds would be preserved for ASAP product purposes.
