Cape Grim Baseline Air Pollution Station - Atmospheric Radon (Rn222) concentration datasets (1986 - 2004)

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).

澳大利亚联邦科学与工业研究组织（CSIRO）凯普格里姆基线空气污染站档案——小时级大气氡（Radon, Rn222）浓度数据集。
凯普格里姆基线空气污染站位于塔斯马尼亚西北端（南纬40°41′，东经144°41′），由澳大利亚气象局资助并管理，其科学项目由CSIRO海洋与大气研究部联合监管。该站的核心职能为通过测量二氧化碳、臭氧、卤代烃、氮氧化物、颗粒物、降水化学组分等大气污染物，以及监测太阳辐射与气象变量等其他参数，实现全球空气质量观测。
本档案包含无色、天然存在的放射性稀有气体氡（Radon, Rn222）的大气浓度实测数据，该气体由镭衰变产生，隶属于澳大利亚核科学与技术组织（ANSTO）凯普格里姆氡项目。数据集涵盖1986年12月至2004年12月期间的大气氡浓度观测值。
变量数据可采用两种形式获取：一是按小时平均的年度文件，二是整合所有年份数据的单文件，均以ASCII（.dat）格式存储，每个文件内均采用澳大利亚东部标准时间（AEST）的时间与日期格式，浓度以校准后的1小时计数单位表示。
