Atmospheric methane (CH4): Trends and seasonal cycles

Rasmussen, R. A., Khalil, M. A. K.·1981·Journal of Geophysical Research: Oceans

Abstract

On the basis of 22 months of almost continuous, automated, GC/FID measurements of atmospheric CH 4 at Cape Meares (45°N), we show that the concentration of CH 4 is increasing at about 2% per yr (±0.5% yr−1). The data also revealed stable seasonal cycles with peak concentrations in October and minimum concentrations in July. The magnitude of the seasonal variations during these months is about ±20 ppbv from the average (∼±1.2%). If the current trend continues, the increased CH 4 concentration may result in a 0.2°K to 0.4°K average increase in earth's surface temperature over the next 40 years or so (based on calculations of Wang et al. (1976)). The coupling of CH 4 to tropospheric and stratospheric chemical processes is discussed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
