Dear Ervin,
Thank you for contacting NSIDC. Are you inquiring about determining snow depth with satellite data or physically measuring snow?
Here are some information resources about physical snow measurements:
National Weather Service Snow Measurement Guidelines
http://www.crh.noaa.gov/iwx/program_areas/snow_spotters/SnowMeasurement.pdf
"the depth of snow on the ground includes both new snow and
old snow which was in
place. Measure the total snow depth at several locations in your yard which
have not
drifted or blown. Take an average of these measurements to arrive at the snow
depth.
Sometimes old snow can be very hard and crusty underneath the new snow. Be sure
that
the ruler gets all the way down to the underlying ground. Snow depth is
measured to the nearest inch."
