hasSummary
  • 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.
