The "Measuring Snow" video is a 23 minute instructional video. This video
was prepared by Colorado State University as instructional material for
National Weather Service Cooperative Observers.
The video is now available for general instruction. All examples of
measurement show the large 8" diameter NWS standard rain gauge. The same
basic instructions apply for the 4" diameter plastic gauge used by
most CoCoRaHS volunteers. The 4" gauge has a smaller capacity and is more
fragile than the large metal gauge used by most National Weather Service
official stations. The 4"-diameter gauge is more prone to "undercatch"
for conditions of wind-driven snow. However, when sited properly and
used according to instruction, very good results can be expected. The 4"
gauge is easy to use for taking snow core samples of the water content of
fresh snow and the total snow water equivalent.
Good luck with your snow measurements, and enjoy the show.
