The Aerological Observatory (AO) was established at Tsukuba in 1920 specializing in upper air meteorology. The Observatory, currently one of the auxiliary organs of the Japan Meteorological Agency, is in charge of upper atmosphere, radiation and the ozone layer with instruments on the ground or sondes reaching up to about 30 km. Relevant researches here contributes to operational weather forecasts, monitoring of climate change and the global environment. The aerological data and radiation data are provided from AO to the GEWEX Baseline Surface Radiation Network (BSRN) project, where the CEOP Tsukuba project is achiving both of types of data.
