SIGMA-A Automatic Weather Station (AWS)
The SIGMA-A Automatic Weather Station (AWS) Data Graph provides a variety of real-time data, including air temperature, relative humidity, wind speed, wind direction, up and down shortwave radiation, up and down longwave radiation, up and down near-infrared radiation, surface air pressure, snow height, snow temperature, and more. The SIGMA-A site is located on northwest Greenland ice sheet (78°03’N, 67°38’W, 1,490 m a.s.l). This AWS is maintained and operated by SIGMA Project, which supported by The Ministry of Education, Culture, Sports, Science and Technology (MEXT), Grant-in-Aid for Science Research (S) (PI: Teruo Aoki, Meteorological Research Institute).
