From in situ measurements made over a 20 - month period by the Tunable Laser Spectrometer (TLS) of the Sample Analysis at Mars (SAM) instrument suite on Curiosity at Gale Crater, we report detection of background levels of atmospheric methane of mean value 0.69 ± 0.25 ppbv at the 95 % confidence interval (CI).
All this modelling work, combined with in situ measurements (oceanographic campaigns recently carried out as part of the AMOP project) help improve our understanding of the interactions between biogeochemistry, atmospheric circulation and oceanic circulation.
Pages 137 - 140 of IPCC AR4 describe high - precision in situ measurements of atmospheric CO2 at Mauna Loa, documenting the steady increase in CO2 along with its characteristic seasonal fluctuation.
Also, while we have good atmospheric measurements of other key greenhouse gases such as carbon dioxide and methane, we have poor measurements of global water vapor, so it is not certain by how much atmospheric concentrations have risen in recent decades or centuries, though satellite measurements, combined with balloon data and some in - situ ground measurements indicate generally positive trends in global water vapor.»
Maintaining and enhancing the current observational network of remotely sensed and in - situ measurements that can be used to infer changes in the atmospheric circulation is essential.
