Syowa
Reference CryoNet Station Information

Syowa Station was established on East Ongul Island, Lutzow- Holm Bay, on January 29 in 1957 by the 1st Japanese Antarctic Research Expedition. At present, it also acts as an observation site for world meteorological network in addition to various scientific observations.

Measurement Notes and Other Measurements

Category Description or List
SnowSnow depth has been observed continuously by using ultrasonic snow gauge since 1999. Snow depth on sea ice is also observed by using snow scale. Although albedo data are not published, upwelling shortwave radiation was observed as well as downwelling shortwave radiation since 1998.
AtmosphereMeteorological observation at Syowa station started in February 1957 and has been made continuously by dispatched staff from the Japan Meteorological Agency for about 50 years (except for 1958 and 1962-1966.) Archived observation data has been widely used for studies and monitoring of global environment through international frameworks.

In terms of radiation observation, downwelling shortwave radiation has been observed since 1961 based on the project for Baseline Surface Radiation Network (BSRN) in the framework of World Climate Research Programme (WCRP). Observations of diffuse shortwave radiation, downwelling shortwave and longwave radiant quantities, UV-B radiation and spectral ultraviolet solar radiation started in 1991, and upwelling shortwave and longwave radiation in 1998 based on BSRN.
