Is it measured directly or computed via instrumentation? <br /><br />Direct method example: <br /><br />http://www.nws.noaa.gov/om/forms/resources/FAASnowTraining_nopolicy030311Final.pdf<br /><br />Indirect method example: <br /><br />https://www.campbellsci.ca/snow-water-equivalent-measurement<br /><br />The above examples ignore estimates of SWE involving the remote sensing methods described here: http://www.nohrsc.noaa.gov<br /><br />GaryNL7Yhttps://www.blogger.com/profile/15874712728971005352noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-37773984873045429542017-03-01T10:10:08.071-09:002017-03-01T10:10:08.071-09:00Good question Gary.

There is SWE data back to 1983 from the Fairbanks Snotel site, and I just discovered that the GHCN data for Fairbanks airport includes SWE from October 1952 through January 2001. Not sure why it is missing for more recent years.<br /><br />Based on the GHCN data, the average peak SWE is right around 4.0", which translates to 21 lb per square foot. The record highest SWE was 13.1" on April 14, 1991. I'll do some more analysis and put up a post.<br />Richard Jameshttps://www.blogger.com/profile/08313902028896263276noreply@blogger.comtag:blogger.com,1999:blog-4572286363399496963.post-51718017715672037242017-02-28T22:22:16.786-09:002017-02-28T22:22:16.786-09:00Richard are there historical records for snow wate...Richard are there historical records for snow water equivalent or accumulated snow loads in pounds per square foot available? Might make for an interesting comparison to Figure 3 above. Wet versus dry winter snows?<br /><br />Current snow load: https://nwschat.weather.gov/p.php?pid=201702282355-PAFG-WWAK83-SPSAFG<br /><br />GaryNL7Yhttps://www.blogger.com/profile/15874712728971005352noreply@blogger.com
