The vertical height of frozen precipitation on the ground. For this purpose, frozen precipitation includes ice pellets, glaze, hail, any combination of these, and sheet ice formed directly or indirectly from precipitation.
The thickness of accumulated snowfall on the ground.
the combined total depth of both old and new snow on the ground
A measurement of the depth of snow on the ground made either since the snow began falling or since a previous observation. The total accumulation is equivalent to the total snow depth during a storm, or after any single snowstorm or series of storms. Snow accumulation can vary due to settling and melting and will therefore vary depending on how often it is measured. For example, if new snow is measured every hour during a relatively long duration storm, it is likely that the summed accumulations may exceed a total snow accumulation measured only once at the end of the storm.
An average of the vertical measurements of the depth of the snow measured at the snow course sample points and recorded to the nearest inch. Snow depth at aerial markers is estimated to the nearest half foot unless a ground measurement is made.
The actual depth of snow on the ground at any instant during a storm, or after any single snowstorm or series of storms.
Same as snow accumulation.
