CO2 data Cape Ferguson
Monthly surface flask samples are collected from the AIMS Jetty at Cape Ferguson from June 1991 for measurements of atmospheric carbon dioxide as measured in air samples. Flask samples are sent to the CSIRO’s Atmospheric Composition and Chemistry (ACC) group for analysis of trace gases, particulate matter and chemical processes of the atmosphere.
Data is then submitted to the World Data Centre for Greenhouse Gases data archive operated by the Japan Meteorological Agency (JMA) under the Global Atmosphere Watch (GAW) programme of the World Meteorological Organization (WMO).
This record describes the monthly CO2 records. An analysis shows a similar trajectory to results of monthly average CO2 measurements at the Mauna Loa Observatory, Hawaii, where readings commenced in in March of 1958. The data is presented in a excel file, which is periodically updated as new data is made available.
The full dataset with additional gas species CO2, CH4, N2O, 13CO2, CO, H2. is available for download from the World Data Centre for Greenhouse Gases website via registration - https://gaw.kishou.go.jp/
