[AAS04-17] FLUXCOM remote sensing data based CO2 flux products: overview and synthesis
Keywords:Terrestrial Carbon Cycle, Data-driven model, FLUXNET, FLUXCOM, Remote Sensing
FLUXCOM-RS GPP and NEE are generally consistent with other estimations, such as SIFs and inversion-based net CO2 fluxes over temperate and boreal region in terms of mean seasonal variation. In addition, interannual variations in FLUXCOM-RS GPP are consistent with those of SIFs at sub-continental scales over temperate and boreal regions. On the other hand, discrepancies in GPP and NEE were found over tropical regions, e.g. Amazon. The FLUXCOM-RS products also show generally consistent seasonal variation with regional specific empirical upscaling in Alaska and Asia. Therefore, these products could also be used for regional analysis. The comparison with FLUXCOM-Met shows that FLUXCOM-RS products capture more clear spatial patterns in CO2 fluxes, and only FLUXCOM-RS can capture CO2 flux changes due to human activity (e.g. afforestation, fire). These evaluation suggests that FLUXCOM-RS be a promising and provide additional data sets to analyze terrestrial carbon and energy cycles.
