Trace gas datasets
ServiceNIWA makes a range of trace gas data freely available on our FTP site. -
Carbon dioxide
FacilityAtmospheric carbon dioxide (CO2) is measured continuously at Baring Head, providing the longest running record of this type in the Southern hemisphere. -
Methane
FacilityMethane (CH4) is the second most important greenhouse gas after CO2 that is produced by human activities. -
Scientists attribute rising methane levels to agriculture
Media release11 March 2016A breakthrough in understanding about the causes of climate change has today been published online in the prestigious international journal Science. -

Early Christmas present for Antarctic researchers
News article08 December 2014In a small green laboratory perched on the rocky volcanic southern peninsula of Ross Island, Antarctica, there’s a space waiting for a new shiny, hi-tech Christmas present. -
Carbon monoxide
FacilityCarbon monoxide (CO) plays a key role in atmospheric chemistry because it is the largest sink for hydroxyl radical (OH). OH is often called the 'detergent' of the atmosphere because it destroys many harmful pollutants. -
Scientists discover abrupt increase in CO2 uptake by the land biosphere
News article12 July 2012Scientists have discovered an abrupt increase in the uptake of atmospheric carbon dioxide by the land biosphere since1988. Without this natural increase in uptake, the amount of carbon dioxide in the atmosphere would probably have increased even more rapidly over the last two decades. -
Chemistry-climate modelling
Research ProjectThis research project focusses on modelling atmospheric chemistry and climate from the surface to the top of the stratosphere, using sophisticated chemistry-climate models. -
