Summary

Abstract: [From the online documentation for CSIRO GASLAB CH4 data]:

The listed data have been obtained from flask air samples returned to
the CSIRO GASLAB for analysis. Typical sample storage times range from
days to weeks for some sites (e.g. Cape Grim) to as much as one year
for Macquarie Island and the Antarctic sites. Experiments carried out
to test for any change in sample CH4 mixing ratio during ...
