The discovery of methane in the atmosphere of Mars provides an example of an atmospheric disequilibrium that has been detected by remote spectroscopy.
“The discovery of methane in the atmosphere of Mars (Formisano et al., 2004; Krasnopolsky et al., 2004; Mumma et al., 2004, 2009) provides an example of an atmospheric disequilibrium that has been detected by remote spectroscopy.”

“Observed atmospheric methane could be consistent with a variety of mechanisms that include subsurface biological methane production (Krasnopolsky et al., 2004), volcanic release, release from ancient sediments and clathrates (ice structures that capture gases and release the gas when destabilized)…”

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.
