Figure 6.
In an effort to calibrate the Belfort measurements of solid precipitation amount at the Saddle, event measurements were made in 1997 using a 1000 cc density cutter and Acculab field scale (precision +- 1 gram). For each event, a snowpit was excavated down to the old snow surface or to the ground and density measurements were made in the wall of the snowpit continuously in 10-cm increments from the snow-atmosphere interface to the old snow surface. Wind speed was measured continuously at a height of 2 meter by a RM Young anemometer. Here we report average wind speed for the duration of the snow event. Access to the site involves a 2-hr ski which must be made at the correct time in order to make hand measurements of storm amounts, explaining the scarcity of data points in this figure.
