GHRC released two snow-related datasets from the Global Precipitation Measurement (GPM) Cold-season Precipitation Experiment (GCPEX) in Ontario, Canada during winter 2012: Environment Canada (EC) Manual Precipitation Measurements GCPEx and Environment Canada (EC) Snow Surveys GCPEx. The manual observations were collected using a Tretyakov gauge inside a double fence intercomparison reference (DFIR) shield, which recorded precipitation amount, weight, snow water equivalent and present weather condition. The snow surveys recorded snow depth, water equivalent, density, and snow water equivalents from 2 different transects at the GCPEx sites using a snow corer and a GPS equipped snow depth probe.
