A diurnal cycle in near-surface methane concentration from micro-seepage as constrained by TLS and TGO
Abstract
The constraint on the methane content of the bulk martian atmosphere provided by TGO allows the expected variation in near-surface methane content to be quantified for constant micro-seepage. Under these circumstances, fluxes may be derived directly from MSL-TLS measured near-surface methane concentrations and are consistent with the low upper limit on methane derived in the middle and upper atmosphere by TGO.
