CFC Measurements along 26N and CFC and Carbon Measurements at the Western Boundary

摘要/ abstract摘要：本研究为2004年冬季在英国北纬26度样带测量氯氟烃（CFC-11、CFC-12、CFC-113）的建议。目标是提供高质量的数据集，并根据全球重复计划的要求，几乎立即向社区提供这些数据。该计划支持CLIVAR（气候变率和可预测性）和国际碳循环计划，是全球物理气候/二氧化碳系统观测系统的一个组成部分。这些数据将有助于记录和理解通风和海洋碳是如何随时间变化的。拟议测量的智力价值在于，它们将有助于实现全球重复计划的目标：用于模型校准和验证、碳系统研究、自主传感器校准以及深水和浅水质量和通风研究的数据。此外，在2004年占领26N样带的基础上增加CFC测量将填补CFC储量相对较大的区域的地带性空白，并且在西部整个水柱中迅速增加。拟议测量的更广泛的社会影响包括：广泛和几乎立即传播数据，以加强科学和技术的理解；收集高质量数据集的社会效益，利用这些数据评估气候变化，并为气候系统的模式校准提供资源。二氧化碳是大气中影响地球辐射平衡的最重要的气体之一。一些估算人为CO2使用CFC数据的替代方法，尽管仍然是间接的。资助的测量将有助于量化海洋中人为二氧化碳的存量和通量，并有助于了解其变异性。

ABSTRACTOCE-0351421This is a proposal to measure chlorofluorocarbons (CFC-11, CFC-12, CFC-113) on the U.K. run 26 degrees N transect in winter 2004. The objective is to provide a high quality data set, and make them available nearly immediately to the community as required by the Global Repeat program. The program is in support of CLIVAR (CLImate VARiability and predictability) and the International Carbon Cycle Programs, and is a component of a global observing system for the physical climate/CO2 system. The data will contribute to documenting and understanding how ventilation and ocean carbon change over time. The intellectual merit of the proposed measurements is that they will contribute to the goals of the Global Repeat program: data for model calibration and validation, carbon system studies, calibration of autonomous sensors, and deep and shallow water mass and ventilation studies. In addition, the addition of CFC measurements to the 2004 occupation of the 26N transect will fill a zonal gap in a region where CFC inventories are relatively large, and in the west increasing rapidly throughout the water column. The broader societal impacts of the proposed measurements include: broad and near immediate dissemination of data to enhance scientific and technological understanding; societal benefits of collection of a high quality data set, use of the data to assess climate change, and a resource for model calibration of the climate system. Carbon dioxide is one of the most important gases in the atmosphere affecting the radiative balance of the earth. A number of alternative, although still indirect, means of estimating anthropogenic CO2 use CFC data. The funded measurements will contribute to quantifying the inventory and flux of anthropogenic CO2 in the oceans, and to understanding its variability.
