Background: GPS Derived PWVGPS signal is refracted or delayed by the atmosphereThrough post-processing techniques, the signal delay due to Precipitable Water Vapour (PWV) can be isolatedRequires precise P0 PWV at temporal resolution of 30 to 60 minutesno costly expendablesall weather conditionsAccuracies of 1-2 mm PWV

2006-01-16UofC reprocessed several sites and sent the updated data sets. Sites that were reprocessed as of the above date are Calgary, Cochrane, Olds, Sundre, Sunshine, Three Hills, and Vulcan (1 day). This file has been updated with this new data. All other sites are the same at this point. The result is an increase in the r-squared for the EF4-Calgary, EA3-Olds, and EA3-Sundre comparisons. The average bias for EF4-Calgary changed from -1.6 to 1.3 and the standard deviation changed from 3.5 to 1.3. The bias for EA3-Olds went from -3.1 to -2.2 with the SD changing from 2.1 to 1.9. The bias for EA3-Sundre changed from -4.9 to -3.4 with the SD decreasing slightly.
2006-01-18Changed the ZWD multiplier from 0.15 to 0.16 to be more accurate for summer. This decreased the bias for EF4-Calgary to 0.4 but changed the SD of the bias to 1.60. The bias for EA3-Olds increased slightly to -2.8 with a SD of 1.80. The bias for EA3-Sundre is now -4.0 and the SD is 3.7.
2006-01-20Added re-processed Airdrie data which is calculated using a 3mb offset to the EF4 pressure data. This increased the r-squared to 0.88 and reduced the bias to -0.60 with a SD of 1.60.
2006-01-23Updated Alfred Lake data with newly proccessed data. Alfred Lake uses met data from AB1 (Pressure + 9mb).
2006-09-21Updated U.of C. GPS after re-calculating PWV using pressure and observed temperature (Bevis approximation).
2006-10-04Updated Olds and Sundre GPS after re-calculating PWV using pressure and temperature observed at the GPS site and using the Bevis approximation. Note that met data for Sundre was missing for day 193 so pressure data from Olds GPS was regressed to fill in this gap.
2007-03-13Added GEM data
2007-03-30updated with newest GPS data with ZHD calculated using the Saastomoinen model
