Abstract. We describe sensing of atmospheric column water vapor
in near real-time using the Global Positioning System (GPS).
We use predicted GPS orbits for automated computation of vertical
column water vapor within 30 minutes of GPS data collection.
Based on a 4 month comparison, near real-time GPS column water
vapor agrees with radiosondes and radiometers within 2 mm rms.
Our near real-time column water vapor data are posted hourly at
www.unavco.ucar.edu. They are available for assimilation in numerical
weather models and for other applications.
