Summary
Abstract: This data set consists of whole-air samples are collected in conditioned,
evacuated, 2-L stainless steel canisters; each canister is filled to ambient
pressure over a period of about 1 minute (approximately 20 seconds to 2
minutes). These canisters are returned to the University of California at
Irvine for chromatographic analysis.

The methane growth trend has appeared to level off in recent ... View entire text
