The marine iodine cycle has significant impacts on air quality and atmospheric chemistry. Specifically, the reaction of iodide with ozone in the top few micrometres of the surface ocean is an important sink for tropospheric ozone (a pollutant gas) and the dominant source of reactive iodine to the atmosphere. Sea surface iodide parameterisations are now being implemented in air quality models, but these are currently a major source of uncertainty. Relatively little observational data is available to estimate the global surface iodide concentrations, and this data has not hitherto been openly available in a collated, digital form. Here we present all available sea surface (<20 m depth) iodide observations. The dataset includes values digitised from published manuscripts, published and unpublished data supplied directly by the originators, and data obtained from repositories. It contains 1342 data points, and spans latitudes from 70°S to 68°N, representing all major basins. The data may be used to model sea surface iodide concentrations or as a reference for future observations.
海洋碘循环对空气质量和大气化学有重大影响。具体来说,海表面几微米厚的碘化物与臭氧的反应是消耗对流层臭氧(污染物气体)的重要汇,也是大气中活性碘的主要来源。海表面碘参数化现在已被应用于空气质量模型,但目前这些参数化是一个主要的不确定性来源。目前,可用于估算全球海表面碘浓度的观测数据相对较少,而且这些数据以前没有以整理后的数字形式公开提供。在此,我们呈现所有可获得的海表面(<20 米深)碘观测数据。该数据集包括从已发表的文献中数字化得到的值、直接由原创者提供的已发表和未发表的数据,以及从存储库中获取的数据。它包含 1342 个数据点,涵盖的纬度范围从 70°S 到 68°N,代表了所有主要的大洋。这些数据可用于模拟海表面碘浓度,也可作为未来观测的参考。
