This image of GPS precipitable water is created from delays taken from the California Real-time Network (CRTN) and averaged over the previous hour, with pressures and temperatures calculated from hourly 13-km Rapid Update Cycle analysis.  Sites that are not currently available have "-999" as their value. This image is experimental and may not always be up-to-date, therefore, USE WITH CAUTION!!
