MISSIONMission of our group is "monitoring and modeling of earth system toward better prediction of our future earth." Our approach is to integrate and synthesize of available data and models to understand earth system in more comprehensive ways. Our main target is 'terrestrial biosphere' from regional to global scales. We use network of ground observation (e.g. FLUXNET, AsiaFlux), remote sensing data, numerical models (terrestrial ecosystem models), and atmospheric observations.

Understandings of Terrestrial CO2 Budget Changes at Global Scales by SynthesisUsing bottom-up approach (e.g ecosystem models) and top-down approaches (e.g. atmospheric inversions), we are working on quantification of terrestrial CO2 budget at various scales (e.g. global, southeast Asia, Asia). These works can become a contribution to global projects such as Future Earth. [Kondo et al. 2018 Nature Comm.; Kondo et al. 2018 GRL; Ichii et al. 2013]. Data-driven estimation of terrestrial CO2 fluxes

Development of a Terrestrial CO2 Flux Product for GCOM-C SGLI SensorUsing a diagnostic terrestrial biosphere model, AsiaFlux/FLUXNET observation network data, our group is developing a terrestrial CO2 flux (GPP, NPP, NEP) product for GCOM-C SGLI sensor (JAXA's satellite). Our product will be an official research products and released to public.
Satellite-based Monitoring of Vegetation Changes from Regional to Continental ScaleUsing long-term data of satellite remote sensing, we analyzed and detected vegetation and land cover changes from regional to global scales [e.g. Sekizawa et al. 2015; Ichii et al. 2013; Ichii et al. 2002; Kawabata et al. 2001]. |
Top-down and Bottom-up Synthesis toward Better Understandings of Global Carbon Cycle
We are working on synthesis of multiple independent estimations of terrestrial CO2 fluxes. Estimations include top-down approach (atmospheric inversion model) and bottom-up approach (process-based model, data-driven model, satellite products). [Kondo et al. 2015; Ichii et al. 2017]. |
