Meteorological measurements on Midtdalsbreen

Abstract

An automatic weather station (AWS) has been operating in the ablation area on Midtdalsbreen, a north-easterly outlet glacier of Hardangerjøkulen (Fig. 6-2), since October 2000. The station (Fig. 6-6) is owned and maintained by the Institute for Marine and Atmospheric research Utrecht (IMAU), Utrecht University (contact: J.Oerlemans@uu.nl). The station records incoming and outgoing short wave and long wave radiation, air temperature, relative humidity, wind speed and direction, air pressure and distance to the surface. Sampling is done every few minutes (depending on the sensor) and 30-minute averages are stored. The record from this AWS span almost ten years (1st October 2000 to 24th August 2010) with only two data gaps; data is missing for 39 days in summer 2005 and 55 days in spring 2007.
