Dataset: Cape Grim Baseline Air Pollution Station


The Cape Grim program, established by the Australian Government to monitor and study global atmospheric composition, is a joint responsibility of the Bureau of Meteorology and the Commonwealth Scientific and Industrial Research Organisation (CSIRO). The Cape Grim Baseline Air Pollution Station began taking samples of the atmosphere over twenty years ago. Since the first sampling began in April 1976, there have been more that 3 billion measurements taken. Among these are measurements of green house gases such as carbon dioxide, methane and nitrous oxide as well as chemicals which deplete the ozone layer. Since the station first began in 1976, a 10% increase in carbon dioxide (one of the main greenhouse gases) has been measured. In addition long term records of aerosol particulates, radon and solar radiation have been obtained. As well as monitoring a wide range of atmospheric trace gases, Cape Grim measures concentrations of natural and anthropogenic particles, and meteorological parameters including wind speed and direction, rainfall, temperature, humidity and air pressure. Sophisticated measurements of solar radiation, including harmful UV-B radiation, are also carried out.
