Snowmelt time-lapse


This time-lapse video shows the spring melt-off for the snowpack at the larch lysimeter site from 27 March to 6 April 2015. The 10 day period was captured at 5 minute intervals with a time-lapse camera. On 18 March the snowpack was measured at 25.3 cm SWE (depth 65 cm). The period starts with nighttime temperatures below freezing, but mean daily temperatures rise steadily from around 6 degrees C to around 12 degrees C, and there is frequent rainfall of up to 6.5 mm/h and 32 mm/day.
