The CSIRO archive of Cape Grim Baseline Air Pollution Station - Hourly Atmospheric Radon (Rn222) concentration datasets. The Cape Grim Baseline Air Pollution Station facility, located at the North/West tip of Tasmania (40° 41'S, 144° 41'E), is funded and managed by the Australian Bureau of Meteorology, with the scientific program being jointly supervised with CSIRO Marine and Atmospheric Research. The role of the station has been to observe global air quality through the measurements of atmospheric pollution such as carbon dioxide, ozone, halocarbons, oxides of nitrogen, particulates, precipitation chemistry as well as to monitor other parameters such as solar radiation and meteorological variables. This archive contains measurements of atmospheric concentrations of the colorless, naturally occurring, radioactive noble gas Radon (Rn222), that is formed from the decay of radium gas as part of the Australian Nuclear Science and Technology Organisation's (ANSTO) Cape Grim Radon Program. Containing measured atmospheric Radon concentrations for the period from Dec 1986 until Dec 2004. Variable data is available as both an hourly averaged annual file or as a single (all years concatenated) file in Asci (.dat) format with Australian Eastern Standard Time (AEST) time and date formats within each file (Concentrations in calibrated one hour long counts).
