[AAS04-P05] Monitoring Carbon Cycle Change using an Integrated Observation, Modeling and Analysis System - Project summary
Keywords:Monitoring Carbon Cycle Change, Integrated Observation, Modeling and Analysis
The main progress over the past three years (FY 2014-2016) have been the better constraints of global, continental and regional carbon budgets, and detection of terrestrial carbon cycle change particularly in the Asia-Pacific region.
1) Multiple approaches including different types of top-down models and bottom-up upscaling techniques contributed to designate uncertainties in the estimates of large emissions (e.g. fuel use and land use changes).
2) Key target regions and events were indicated as potential hot-spots in the Asia-Pacific where we need further targeted research. (e.g. potential increase in terrestrial carbon sink in Siberia and East Asia, uncertainty in the recent rapid growth of anthropogenic GHG emissions in East Asia, emissions from land use change and El Niño-induced extreme forest fires in Southeast Asia)
3) A prototype system was developed and tested for future operational monitoring of changes in regional, continental, and global GHGs budgets based on integration of observation and modeling.
4) Scientific knowledge transfer and educational outreach were provided through domestic and international society activities, training seminars, lectures, and publications.
We also discuss remaining issues and the way to solve them in the next steps (e.g. strategies of intensive observations in targeted area, and a platform for multi-model ensemble)
