Snow measurement is inherently inexact, but sticking to the guidelines helps. First, understand the difference between snow depth and snowfall.
When snow is collected, the container is removed and replaced with a spare one. The snow is then melted while it is still in the container, and then poured into a glass measuring graduate. While the depth of snow is normally measured in centimetres, the measurement of melted snow (water equivalent) is in millimetres. [citation needed]
When measuring snowfall on a snowboard, the snowfall is measured to the nearest 0.1 in (0.25 cm). [2] The snow may be measured as often as necessary during a 6-hour period in order to record the greatest depth on the board, since snow may both accumulate and melt during the same 6-hour period. [5]
An ultrasonic snow depth sensor. Depth – Depth of snow is measured with a snowboard (typically a piece of plywood painted white) observed during a six-hour period. At the end of the six-hour period, all snow is cleared from the measuring surface. For a daily total snowfall, four six-hour snowfall measurements are summed.
All SNOTEL sites measure snow water content, accumulated precipitation, and air temperature. Some sites also measure snow depth, soil moisture and temperature, wind speed, solar radiation, humidity, and atmospheric pressure. These data are used to forecast yearly water supplies, predict floods, and for general climate research.
The measurement of the April water content in the snowpack is 110% of normal and is a key indicator for future water supply. ... measure snow depth during the April snow survey, the last one of ...
When it comes to measuring snow cover on the ground, typically three variables are measured: the snow cover extent (SCE) — the land area covered by snow, snow cover duration (SD) — how long a particular area is covered by snow, and the snow accumulation, often expressed as snow water equivalent (SWE), which expresses how much water the snow ...
