TCCON

The Total Carbon Column Observing Network (TCCON) is a global network of instruments that measure the amount of carbon dioxide, methane, carbon monoxide, nitrous oxide and other trace gases in the Earth’s atmosphere. There are two TCCON instruments in Australia: Darwin and Wollongong (and one nearby in Lauder, New Zealand).

The Wollongong TCCON instrument began atmospheric trace gas measurements in June 2008. Measurements of other meteorological parameters (wind speed/direction, outside temperature and humidity) began in February 2009. The most recent data released from the Wollongong instrument ends October 31st 2015. Here is that data.
