The SIGMA-B site is located on Qaanaaq ice cap of northwest Greenland. The surface condition is snow in winter and snow or ice in summer. An automatic weather station (AWS) was installed on 19 July 2014. In summer seasons after 2012 short-term intensive meteorological and glaciological observations were carried out. The characteristics of the SIGMA-B AWS are (1) one-level measurements of air temperature, relative humidity, wind speed and direction; (2) net radiation measurements in the shortwave and longwave spectral regions; (3) monitoring of the surface condition with an interval camera; and (4) tilt angle monitoring of the main AWS pole with an inclinometer. For all instruments, one-minute sampling and ten-minute averaged data are stored on a data logger, and the hourly data are transported to us via Argos satellite. The electric power is supplied from cyclone batteries in the snow, which are charged by solar panels.
