A Snow Water Equivalent (SWE) Sampler is a ground-based device used in the field to measure SWE. A core sample of snow is collected using a snow tube sampler or snow corer. The tube is inserted vertically into the snowpack until it reaches the ground surface, and a ruler on the tube measures the snow depth. The sample is then removed and weighed on a calibrated scale to determine the snow density. The SWE within the sample is calculated by multiplying the snow density by the snow depth.
