GCOS Land ECV - Land Cover

Land cover influences climate by modifying water and energy exchanges with the atmosphere and by changing greenhouse gas and aerosol sources and sinks. The amount of carbon in vegetation is roughly similar to the atmosphere; that in soils is significantly larger. Land-cover distributions are linked to regional climatic conditions, so changes in cover can be due to climate change on a regional scale as well as directly due to human activities.
