Data 

ALE/GAGE/AGAGE data

Emission Data from AFEAS

The entire ALE/GAGE/AGAGE data base comprising every calibrated measurement including pollution events from June 1978 to current is archived here and on the Carbon Dioxide Information and Analysis Center (CDIAC) at the U.S. Department of Energy, Oak Ridge National Laboratory. HFC-227ea, HFC-236fa and HFC-245fa measured by AGAGE GCMS-Medusa instrument are included as part of archived data in August 2011.

Currently there are 33 compounds (see table) available for public access. To download AGAGE data, click on the following link.

The same copy of ALE/GAGE/AGAGE data can also be downloaded from CDIAC.

A copy of presentation, Radiatively Active Global Gas Measurements by the AGAGE and Affiliated Networks, can be downloaded by clicking the following link

 

Monthly means and standard deviations of data currently being archived, under background (un-polluted) conditions, can be seen by clicking the following figures (in PDF format).
