How do the precipitable water computed from radiances from the GOES satellite compare to the precipitable water computed from GPS?

This set of web pages reports on work done for the cal/val project, in which data from GPS are used to compute precipitable water in the atmosphere, and this measure of precipitable water is compared to precipitable water computed from geostationary satellite multispectral measurements.


Use this page to access comparisons for all of 1999 for several station (See below for the station names -- click on them to get to the comparison). The GPS data used is data every 5 minutes every 7 days; the GOES sounder data is hourly for the entire span of time -- that is, it is more complete (it contains holes only during cloudy periods).
