The GOSAT satellite detects increases in atmospheric methane concentration and seasonal variation reliably

The GOSAT satellite detects increases in atmospheric methane concentration and seasonal variation reliably

Researchers indicated that methane measurements of the Japanese GOSAT satellite are sufficiently accurate to detect seasonal fluctuations and increase of methane concentration across the globe.

Seasonal fluctuations and the increase of concentration varies remarkably depending on the region. Variations are associated with local methane sources and sinks as well as atmospheric transport. The observations obtained by satellite can be utilised in modelling methane sources and in determining the exact causes of temporal variations in methane concentration.
