The Italian Meteo-Climatological Observatory in Antarctica: Snow Accumulation Measurements by means of an Automatic Weather Station Network
 Entry ID: Meteo_Clim_Observ_snow


[ Update this Record ]

Summary
Abstract: A network for snow depth measurements was started with 4 Automatic Weather
Stations in 1987 around Terra Nova Bay (North Victoria Land). It provides
continuous meteo-climatological data and information, according to standard and
reliable procedures, making use of robust methodologies and testing new
procedures. At present, we operate a network of 13 Automatic Weather Stations
working year-round plus 3 working during summer only. Data are achieved,
validated, archived and diffused, and instruments are maintained.

Quality
Snow depth sensor is a Campbell Scientific SR50 ultrasonic distance sensor
emitting acoustic pulses and measuring their travel time. Its accuracy is +/-
1.0 cm or +/- 0.4% of distance to target whichever is greater.
