Fig. 2. Daily cumulative precipitation, snowmelt, forest floor (FF) leachate and weekly snowpack water equivalent (SWE) (± standard error) for the period from when the chemical and isotopic tracers were applied (18 Feb. 2004) to the end of the snowmelt (22 Mar. 2004). Vertical bars indicate the daily quantity of precipitation (snow, rain, or snow–rain mix) at the study site with the scale shown on the secondary y axis.
