Automatic weather station buoy data PS81/506 from Weddell Sea, Antarctica, 2013-2014. The buoy was deployed together with an ice mass balance buoy (see under related) on sea ice station PS81/506 from Research Vessel Polarstern in the Antarctic Weddell Sea in austral winter 2013 (cruise leg ANT-XXIX/6, AWECS campaign). The automatic weather station provides data between 2013-07-12T14:00 and 2013-08-13T14:00. Time is in UTC. ... : Automatic weather station (AWS) description:============================================- Data contains date time, air temperature, relative humidity, incoming shortwave radiation, snow depth, wind speed and direction, snow particle counters for snow drift, latitude and longitude.- See drawing PS81-506_AWS.pdf (=> Further details) for installation details.- Processing done here is only correction of snow depth for temperature, and correction of relative to absolute wind direction. To correct wind direction data for floe rotation, data from IMB was used. However the IMB GPS receiver gave positions with a high degree of scatter (>50m), and was unusable for floe rotation correction, therefore IMB magnetometer data was used. Offset between wind direction from the AWS and from the Polarstern is -4° (using average of data from first 22 hours after AWS installed). Therefore at installation on 2013-07-12T14:15 UTC: [true wind direction] = [AWS wind direction - 4°]- Snow depth quality good range is 152 - 210.- ...
