Snow Depth Estimation Method

The amount of snow that has fallen relative to liquid-equivalent precipitation rate measurements.

There are two equation variants based on ambient temperature. This is being termed warm weather, where the temperature is warmer than -12.85°C, and cold weather, where the temperature is colder than -12.85°C.

The snow depth estimate does not account for the processes that affect snow density once the snow is on the ground.
