January and February 2017 Radiosonde Precipitable Water

Comparison to Historical Record (Since 1948)

The Top 20 Precipitable Water (PW) Values for selected Radiosonde Stations in CA, NV and OR were calculated using the data from the soundings in January and February 2017 along with the data collected by the National Weather Service Office in Rapid City, South Dakota (https://www.weather.gov/unr/uac) from the (1) NCDC Radiosonde Database of North America CD-ROMs, 1948–1996/97 and (2) NOAA/ESRL on-line radiosonde archive, 1996/97–1/4/17 (https://esrl.noaa.gov/raobs/). The climatology for some of these sites includes two or more stations in order to obtain a lengthy time series for calculating statistics. In general, the combining of sites should not be problematic since these plots represent a synoptic signal and not a mesoscale signal.
