Historic CH4 Records from Antarctic and Greenland Ice Cores, Antarctic Firn Data, and Archived Air Samples from Cape Grim, Tasmania in CDIAC/Trends Online
Entry ID:
CDIAC_CH4_LAWDOME
Summary
Abstract:
This data represents one thousand years of atmospheric methane concentrations.
Methane concentrations was measured in air bubbles from 1008-1980 in Antarctic ice cores, and from 1075-1885 in Greenland ice cores. Air in firn samples from 1978 to 1993 are also included as well as archived air samples from Cape Grim, Tasmania for the years 1978-1995. For more information on methodology and access to ...

Quality
The quality of the data varies depending on the registered parameter. The
radiation measurements are data integrated every 24 hours, hourly averages and maximum and minimum values. The temperature registries are hour averages, maximum and minimum values. The relative humidity is an hourly average, maximum and minimum values. The precipitations are data integrated every 24 hours and the route of the wind corresponds to an integration of all the campaign.
Access Constraints
Restricted, with the approval of the main investigator
Use Constraints
