REAL-TIME WATER VAPOR SENSING WITH SUOMINET -- TODAY AND TOMORROW

SuomiNet, a university-based GPS network provides real-time atmospheric sensing capability via the Internet for research and education. SuomiNet is funded by the U.S. National Science Foundation and university costshare, and is managed by the University Corporation for Atmospheric Research (UCAR). We present examples of real time PW data products currently provided by SuomiNet, and describe real time slant delay analysis and applications that are proposed as an augmentation of SuomiNet.
