Several automated gauges were used at the site, including the GEONOR T-200B, the OTT Pluvio, and the Hotplate snow gauge. The wind-shields installed at the site were a Double Fenced Intercomparison Reference (DFIR), a standard Alter, and a double Alter, all which were installed around GEONOR gauges. Additionally, the OTT used a Tretyakov-style shield and the Hotplate required no shield.
Snow-pan observations were done using metal pans (30 cm x 50 cm with a 1 cm lip) that were exposed to the precipitation for ten-minute periods. Each pan was weighed before and after exposure to the precipitation so the actual snow LWE accumulation could be calculated. Ten-minute LWE accumulations were calculated from the other automated gauge/shield combinations at the site and the data compared to the snow-pan measurements. Data from the gauge/shield combinations were accumulated over the same ten-minute period as the snow-pans and then compared to the snow-pan data. These comparisons will be presented and conclusions shown regarding the correlation of the automated gauges to the snow-pan measurements.
