Variability of surface methane concentration in moscow at different time scales
Abstract
Abstract— The variability of surface methane (СН4) concentration in Moscow at different time scales is analyzed using long-term regular measurements from the State Environmental Institution Mosecomonitoring (2005–2020). Possible mechanisms that form the methane-concentration field in the city’s atmosphere are discussed. The average concentration of methane in the urban surface layer during the cold half of the year is lower, the higher the average air temperature of the previous warm half-year. The lowest methane concentrations in Moscow in 2010 and 2011 are associated with the hot summer of 2010, which was accompanied by severe wildfires and partial dry-out of wetlands in central European Russia. The intra-annual variations in СН4 concentration exhibit minima in summer and maxima in winter. An additional maximum concentration in August–September is typical only of the night methane concentrations. In the diurnal cycle, there is a higher methane concentration in the air at night than during the day. The results demonstrate the complexity of multidirectional natural processes in the atmosphere and at the underlying surface that form a dynamically changing field of methane concentration in the surface air of a megacity.

Certain atmospheric features interact with each other to produce effects on methane concentration, for example solar radiation and ozone.
“As it is known that certain atmospheric features interact with each other to produce effects on methane concentration, for example solar radiation and ozone (Vinogradova et al., 2022), we decided to also test a feature set including interactions between our considered features.”

Weather monitoring stations often measure other relevant parameters such as ambient air temperature, wind direction, wind speed, barometric pressure, relative humidity, and ozone, which may affect CH4 concentration.
“Moreover, weather monitoring stations often measure other relevant parameters such as ambient air temperature (AT), wind direction (WD), wind speed (WS), barometric pressure (PB), relative humidity (RH) and atmospheric concentration of other gases such as ozone (O3), which may affect the concentration of CH4 (Zona et al., 2016; Delkash et al., 2016; Vinogradova et al., 2022).”

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.
