Atmospheric CO Concentrations from the CSIRO GASLAB Flask Sampling Network
Individual measurements have been obtained from flask air samples returned to the CSIRO GASLAB. Typical sample storage times range from days to weeks for some sites (e.g. Cape Grim) to as much as 1 year for Macquarie Island and the Antarctic sites. Experiments carried out to test for changes in samp...

Individual measurements have been obtained from flask air samples returned to the CSIRO GASLAB.

Corrections derived from the test results are applied to network data according to flask type. (Data from the S160 flasks have been rejected due to large and variable drift.) An annual cycle of CO is evident, largely due to an increase in its destruction by the OH radical during the summer months.
