Near real-time GPS sensing of atmospheric water vapor
Listed in National Center for Atmospheric Research
We describe sensing of atmospheric column water vapor in near real-time using the Global Positioning System (GPS).
Description
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.
