SESSION 3C2 - CARBON AND KYOTO

摘要

This session contained five papers, one concernedrnwith the global datasets needed for terrestrialrncarbon cycle models, three more directly dealingrnwith the information needs for the Kyotornprotocol, and one investigating the use ofrncoherence to infer forest age and thence therncarbon flux. In all cases the talks described workrnin progress with interim results.rnThe GLOBCARBON project described in the firstrntalk is a recognition by ESA that the progress ofrncarbon cycle science will be much enhanced byrnproviding products (e.g. LAI, burnt area) matchedrnto the needs of climate and dynamic vegetationrnmodels. This is a significant change in outlookrnfrom the past provision of data rather thanrn‘information’. Examples were given of interimrnproducts. However, the final products and theirrnrelease to the modellers is contingent on thernongoing evaluation of these products.rnThe three Kyoto studies, in Switzerland, Spainrnand Indonesia presented very differentrncircumstances. In Switzerland the issue wasrnmainly one of land cover mapping, and resultsrnshown were encouraging enough to go furtherrnwith evaluating remote sensing, along with theirrnother information sources. In Spain, probably thernmost important finding was the ability of MERISrnto provide information on fire damage.rnThe Sumatran study demonstrated the ability ofrnASAR to provide information on the planting andrndeforestation in plantation forest.rnThe fifth talk attempted to relate a soil-plantatmospherernmodel to a coherence model tornexplain observed environmental effects onrncoherence. Although general trends werernexplainable, the magnitude of the fluctuationsrnwere not reproduced by the model, necessitatingrnan empirical approach to recovering age fromrncoherence.
