Abstract:
The meteorological observation in northwestern Greenland was conducted as a part of the "Snow Impurity and Glacial Microbe effects on abrupt warming in the Arctic (SIGMA)" Project supported by Japan Society for the Promotion of Science (JSPS), Grant-in-Aid for Scientific Research, number JP23221004 and JP16H01772, the Global Change Observation Mission-Climate (GCOM-C) research project of Japan Aerospace Exploration Agency (JAXA), and the Arctic Challenge for Sustainability II (ArCS II), Program Grant Number JPMXD1420318865. An automatic weather station (AWS) has been 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. The measured data are collected through the ARGOS satellite network in semi-real time every day.
