Measuring Snow Video


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.
