Research Abstract

Using diagnostic-type biosphere model BEAMS, I analyzed terrestrial carbon fluxes with 1km grid resolution over Far East Asia. As a result of a comparison between model estimations and observations at tower fluxes, I confirmed a validity of water, energy and carbon fluxes estimated by BEAMS. I could demonstrate in regional scale analyses spatial and temporal patterns in gross primary production, net primary production, and net ecosystem production, and the changes in response to climate events.
