Short summary

Soil bacteria known as methanotrophs are the only biological sink for atmospheric methane (CH₄). Their activity depends on climatic and edaphic conditions, thus varies spatially and temporarily. Based on this, we developed a model (MeMo v1.0) to assess the global CH₄ consumption by soils. The global CH₄ uptake was 33.5 Tg CH₄ yr^-1 for 1990–2009, with an increasing trend of 0.1 Tg CH₄ yr^-2. The regional analysis proved that warm and semiarid regions represent the most efficient CH₄ sink.
