Abstract:
East Asia accounts for 20% of global population, is responsible for 30% of global GHG emissions, and experiences rapid land use changes. These facts are likely to substantially alter terrestrial water and carbon cycles; however, little is known about spatial and temporal patterns of carbon and water fluxes in East Asia. In this study, we use the Breathing Earth System Simulator (BESS) which computes gross primary productivity and evaporation between 2001 and 2013 using a series of MODIS Atmosphere and Land products. We have improved BESS by incorporating chlorophyll fluorescence module, updated module of Ci:Ca, and atmospheric stability. We prepare independent data such as NDVI, EVI, and GOSAT-derived fluorescence to cross-check our spatial and temporal patterns of carbon and water flux maps. We investigate how water and carbon fluxes respond to extreme weather events and land use changes in East Asia.
