Recent warming of the Arctic stimulated speculations about dissociation of methane hydrates in the Arctic seabed and a new climatic positive feedback. Here, for the first time, methane low tropospheric satellite retrievals over the Arctic from two instruments: AIRS (Atmospheric IR Sounder) and IASI (Infrared Atmospheric Sounding Interferometer) were analyzed. Analyzed are data for areas over open water with high values of the vertical thermal contrast (ThC, defined here as the temperature difference between the surface and altitude of 4 km); they have been found to be reliable. The seasonal cycles of the data well correlate with the cycles measured …
