GPSRO CLIMATE APPLICATIONS WORKSHOP
March 17 - 18 2008
Boulder, CO
Questions about the potential value of GPS-RO to the climate
observing system and which GPS-RO data are truly benchmark
A COSMIC breakfast meeting was held at the AMS Annual Meeting, January 22, 2008 in New Orleans.
The potential value of GPS-RO to the climate observing system was addressed in a presentation:
In response to Dr. Jay Fein's request, and based on above presentation, Drs. Dian Seidel, Rick Rosen, Tom Peterson, Bill Murray, have tried to articulate a few key questions regarding the potential value of GPS-RO observations for climate and to describe analyses that might answer these questions. The questions particularly address the claim that GPS-RO constitutes a benchmark observing system. Quantitative estimates of the various terms in the overall error budget for observations at a given time and location, as opposed to error estimates based on averages of large samples covering wide space and time scales are requested.
