TL;DR: In this article, the distribution and variations of atmospheric CO2 from 1981 to 1992 were determined by measuring CO2 mixing ratios in samples collected weekly at a cooperative global air sampling network.

TL;DR: The most likely drivers of CH4 anomalies observed during 2007 and 2008 are anomalously high temperatures in the Arctic and greater than average precipitation in the tropics as mentioned in this paper, which suggests we have not yet activated strong climate feedbacks from permafrost and CH4 hydrates.

TL;DR: In this article, a procedure is presented that attempts to extend the knowledge gained during a limited period of measurements beyond the period itself resulting in records containing measurement data and extrapolated and interpolated values.

TL;DR: In this article, the authors used time series from 50 locations to better define the distribution and recent changes of H2 in the remote lower troposphere, showing that the globally averaged H2 mixing ratio between 1991 and 1996 was about 531±6 parts per billion (ppb).

TL;DR: The stable isotopic composition of atmospheric CO2 is monitored via measurements made at the University of Colorado-Institute of Arctic and Alpine Research, using air samples collected weekly by the Global Air Sampling Network of the NOAA Climate Monitoring and Diagnostics Laboratory as mentioned in this paper.
