Single Frequency GPS Water Vapor Network

1 July 2007 - 30 June 2010

Lead Scientist: John Braun

Observatory: sgp, sgp

A network of GPS stations, unique in its density and operational characteristics provided continuous, and all weather observations of atmospheric water vapor over horizontal scales as small as one kilometer. These data were useful for studying water vapor structure, variability, temporal cycles, and evolution during cloud formation and convective events. These observations were used to detect changes in moisture associated with multiple atmospheric processes including: convective initiation, cloud formation, and diurnal heating. The derived products from this network are estimates of column-integrated precipitable water vapor (PW) at 30-minute intervals and line-of-sight slant water vapor (SW) in the direction of each visible GPS satellite at 30-second intervals.
