SIGMA-AWS dataset

These automatic weather station (AWS) data were measured as part of the "Snow Impurity and Glacial Microbe effects on abrupt warming in the Arctic (SIGMA)" Project (link to http://www.mri-jma.go.jp/Dep/cl/cl6/sigma/sigma-e.html) supported by Japan Society for the Promotion of Science (JSPS), Grant-in-Aid for Scientific Research (S), number 23221004. The data set contain 1-hourly meteorological and snow parameters measured at sites of SIGMA-A and SIGMA-B on the northwest Greenland since summer 2012.
SIGMA-A is located on the Greenland ice sheet and SIGMA-B on Qaanaaq ice cap. The measured parameters are air temperature, relative humidity, wind speed, wind direction, air pressure, snow height, downward and upward components of shortwave, near-infrared and longwave radiant flux densities, and snow temperatures. The measured data were received from the ARGOS satellite network in semi-real time every day. Photos of these AWSs are presented in SIGMA Project HP.
