International Reanalysis Cooperation on Carbon Satellites Data

摘要

According to current huge data requirements for the global climate change assessment, DBAR Data Sharing Principles,as well as the national policymaking in response to the global agreement (Framework Convention on ClimateChange (FCCC)) on combating climate change, to reform the research mode of carbon data based exploration, tointegrate carbon satellite data, models and computing technologies to advance interdisciplinary study, and to implement abig earth data e-science platform for global carbon researches are very essential and necessary. Cooperation on theAnalysis of carbon Satellites data (CASA), a new international scientific programme, was approved by the ChineseAcademy of Sciences (CAS) in 2018, which was participated by CAS/Institute of Atmospherics Physics and NationalSuperComputer Center in Wuxi. Massive data resources (standard, value-added carbon satellite products andauxiliary data), relevant analysis models, and the super-computing capacity (100 trillion FLOPs computing power and 1PB of storage) has been integrating into the CASA big e-science platform. Forthcoming products, including carbonsatellites standard products, higher-precision CO2 reprocessed products, and application dataset based on above twokinds of CO2 products, are processed and analyzed online on the CASA e-science platform. The first global XCO2product produced from TanSat will be released at September of 2019. Research mode of carbon data-based is going tobe reformed under the support of big data and supercomputing power.
