Scientific Results from the GPS/MET Experiment (1995-1997)

UCAR began demonstrating the potential of using radio occultation to sound Earth's atmosphere in the GPS/MET experiment from 1995 to 1997. COSMIC has since built on GPS/MET and subsequent radio occultation missions to produce real-time soundings that are tested for their application to operational weather prediction models.

The GPS/MET experiment produced over 80 technical reports and scientific journal publications by May 2000.  While not all of these papers and reports actually use GPS/MET data, they cover a wide range of topics ranging from measurement techniques, retrieval algorithms, and verification studies to data assimilation and impact assessment.  This body of papers is a valuable resource for those interested in learning about the science and technology of radio occultation.

Below we provide a list of references related to GPS/MET; the reference list is broken into two sections: (a) Pre-GPS/MET and (b) Post-GPS/MET. The Pre-GPS/MET section includes publications prior to the launch of the Microlab-1 minisatellite (April 1995). This body of papers covers the early planetary missions and pioneering work in radio occultation techniques. The Post-GPS/MET section includes publications that focus on the retrieval, verification, interpretation, and assimilation of GPS/MET data, as well as on their application to meteorology ionosphere and climate research.
