Observers measure new snow on a flat board painted white, set out in an open spot away from trees, roofs and drifts, so the snow lands where wind has not rearranged it. The board is read at least every six hours during a storm, because snow settles under its own weight and melts from the bottom. A single reading at the end of a long storm runs low. After each reading the board is swept clean, and the storm total is the sum of the readings. Depth on the ground is a different number: it holds older snow and has settled.
