Snow measurements have been collected approximately weekly during the winter season using transects adjacent to the established network of standard rain gages from 1956 to the present. Maximum snow depth, water content and snow cover duration data are recorded at points along a transect known as a 'snow course', which includes 10 points spaced at 2-m intervals within a designated 0.25 ha area. Data from one course are averaged for each collection date and snow water content is scaled up to a whole watershed value.
These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.
