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

摘要：这是一项在英国测量氯氟烃（CFC-11、CFC-12、CFC-113）的提案。 在2004年冬季进行26 ° N样带。 其目的是提供一个高质量的数据集，并使他们几乎立即提供给社区所需的全球重复程序。该计划支持CLIVAR（气候变化和可预测性）和国际碳循环 它是物理气候/CO2系统全球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随时间的变化。拟议测量的智力价值是，它们将有助于实现全球重复计划的目标：模型校准和验证数据，碳系统研究，自主传感器的校准，以及深水和浅水质量和通风研究。此外，在2004年对26 N样带的占领中增加氟氯化碳测量将填补氟氯化碳库存相对较大的区域的地带性空白，并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，以提高科学和技术的理解;收集高质量数据集的社会效益，使用数据评估气候变化，以及气候系统模型校准的资源。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。 估计人为CO2使用量的若干替代方法，尽管仍然是间接的。 资助的测量将有助于量化海洋中人为CO2的清单和通量，并有助于了解其可变性。

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.
