SPECIFICATIONS
Facility TypeFixed
LocationUSA, ~400 stations
VariablesIPW (cm), T(C), P(hPa), RH(%), zenith-scaled total signal delay (m), zenith-scaled hydrostatic signal delay (m), zenith-scaled wet signal delay (m), estimated mean weighted temperature (K), wet delay transfer function (dimensionless), and formal error (equivalent to the RMS of the individual estimates of the zenith total delay) in cm.
Archive Data AvailabilityGPS observations from 1996 available from NOAA's National Geodetic Survey. IPW and measured/derived parameters from 1998 available from NOAA/ESRL.
