Abstract:
Time-series data of an automatic weather station (AWS) operated at the SIGMA-A site on the Greenland ice sheet since June 2012. The AWS measures the meteorological parameters every hour, which are air temperature, relative humidity, wind speed, wind direction, atmospheric pressure, shortwave radiation, longwave radiation, near-infrared radiation, snow height, and snow temperature. This dataset (data level: 1.3) has been completed data masking procedures discriminating all erroneous data records. This dataset contains data version 1.0 and 1.1; the version 1.0 is the initial version, and the version 1.1 has been modified to data mask algorithm of longwave radiation, snow height , and atmospheric pressure. Detailed information of the data version and data level definition is referred to "readme_SIGMA-A_Level_1.3.txt". It is strongly recommended to refer to "Dataset Revision Record" in the readme file and use the latest version of the dataset.
