Short summary

Methane (CH₄) is an important greenhouse gas and contributes to climate warming. However, the input of CH₄ from coastal areas to the atmosphere is not well defined. Dissolved and atmospheric CH₄ was determined at high spatial resolution in or above the North Sea. The atmospheric CH₄ concentration was mainly influenced by wind direction. With our detailed study on the spatial distribution of CH₄ fluxes we were able to provide a detailed and more realistic estimation of coastal CH₄ fluxes.
