<hr /><p> Historical and projected changes in the Annual Maximum Snow Water
Equivalent (SWE), a measure of the total amount of water contained in
the snowpack. Results are shown only for
watersheds with an average historical April 1st SWE of at least 0.4
inch. April 1st is the approximate current timing of peak annual
snowpack in the mountains of the Northwest. Geographic units: HUC10. <br /></p><p>These data include historical
conditions (1970-1999, in inches) and the projected changes (in percent)
for ten global models. Two time periods are considered: the 2040s
(2030-2059) and the 2080s (2070-2099), based on a moderate greenhouse
gas scenario (A1B).<br /></p><p>Data source: Hamlet et al. 2013.</p>
