Modeling modern methane emissions from wetlands 1980-present
Methane is one of the important greenhouse gases and plays an important role in atmospheric chemistry. Its contribution to the current greenhouse effect is about 22%. Since the beginning of the industrialization the atmospheric methane concentration has increased by a factor of 2.5. This increase continues until present, however, since the early 1990s the growth rate has decreased. Superimposed...
متن کاملMethane emissions from western Siberian wetlands: heterogeneity and sensitivity to climate change
The prediction of methane emissions from high-latitude wetlands is important given concerns about their sensitivity to a warming climate. As a basis for the prediction of wetland methane emissions at regional scales, we coupled the variable infiltration capacity macroscale hydrological model (VIC) with the biosphere–energy-transfer–hydrology terrestrial ecosystem model (BETHY) and a wetland met...
متن کاملToward a statistical description of methane emissions from arctic wetlands
Methane (CH4) emissions from arctic tundra typically follow relations with soil temperature and water table depth, but these process-based descriptions can be difficult to apply to areas where no measurements exist. We formulated a description of the broader temporal flux pattern in the growing season based on two distinct CH4 source components from slow and fast-turnover carbon. We used automa...
متن کاملMitigation of methane emissions from constructed farm wetlands.
Constructed wetlands are increasingly used for water pollution treatment but may also be sources of the greenhouse gas CH(4). The effect of addition of two potential inhibitors of methanogenesis - iron ochre and gypsum - on net CH(4) emissions was investigated in a constructed wetland treating farm runoff in Scotland, UK. CH(4) fluxes from three 15-m(2) wetland plots were measured between Janua...
متن کاملMethane emissions from wetlands: biogeochemical, microbial, and modeling perspectives from local to global scales.
Understanding the dynamics of methane (CH4 ) emissions is of paramount importance because CH4 has 25 times the global warming potential of carbon dioxide (CO2 ) and is currently the second most important anthropogenic greenhouse gas. Wetlands are the single largest natural CH4 source with median emissions from published studies of 164 Tg yr(-1) , which is about a third of total global emissions...
