Coupled modeling of peatlands carbon cycle and carbon dioxide emission from their peat deposits
Abstract COmplex Model of BOg LAndscapes (COMBOLA) is a set of dynamic models of carbon and nitrogen turnover, net ecosystem exchange, water balance, heat and water transport, generation and transfer of CO 2 and CH 4 in a peat deposit on a number of time scales. Combined modeling of carbon turnover...
