温室气体的海气通量[例如，二氧化碳（CO2）]是气候系统的一个关键部分，也是海洋生物地球化学发展的一个主要因素。如果研究人员要充分了解和预测未来的气候，就需要对这些气体通量进行更准确和更高分辨率的计算。卫星地球观测能够提供可用于研究气体通量的大型空间尺度数据集。然而，托管此类数据所需的大量存储需求可能会限制科学界对其的使用。幸运的是，云计算的发展可以提供解决方案。本文介绍了一个开源的海气CO2通量处理工具箱，称为“FluxEngine”，设计用于云计算基础设施。该工具箱允许用户从模型、现场和地球观测数据中轻松生成全球和区域海气CO2通量数据，其海气通量计算是用户可配置的。它目前安装在Nephalae Cloud上，使用户能够轻松利用超过8 TB的气候质量地球观测数据来推导气体通量。生成的netCDF数据输出文件包含>20个数据层，其中包含通量计算的各个阶段，沿着过程指示层，以帮助解释数据。本文介绍了工具箱的设计，它验证了海气CO2通量的计算;演示了使用工具来研究全球和大陆架海气通量;并介绍了未来的发展。
The air sea flux of greenhouse gases [e.g., carbon dioxide (CO2)] is a critical part of the climate system and a major factor in the biogeochemical development of the oceans. More accurate and higher-resolution calculations of these gas fluxes are required if researchers are to fully understand and predict future climate. Satellite Earth observation is able to provide large spatial-scale datasets that can be used to study gas fluxes. However, the large storage requirements needed to host such data can restrict its use by the scientific community. Fortunately, the development of cloud computing can provide a solution. This paper describes an open-source air sea CO2 flux processing toolbox called the "FluxEngine," designed for use on a cloud computing infrastructure. The toolbox allows users to easily generate global and regional air sea CO2 flux data from model, in situ, and Earth observation data, and its air sea gas flux calculation is user configurable. Its current installation on the Nephalae Cloud allows users to easily exploit more than 8 TB of climate-quality Earth observation data for the derivation of gas fluxes. The resultant netCDF data output files contain >20 data layers containing the various stages of the flux calculation along with process indicator layers to aid interpretation of the data. This paper describes the toolbox design, which verifies the air sea CO2 flux calculations; demonstrates the use of the tools for studying global and shelf sea air sea fluxes; and describes future developments.
