Abstract The Ocean and Sea-Ice Satellite Application Facility (OSI-SAF) of the EUropean Organisation for the Exploitation of METeorological Satellites (EUMETSAT) has performed a reprocessing of Sea Surface Temperature (SST) from the Spinning Enhanced Visible and Infrared Imager (SEVIRI) onboard Meteosat Second Generation (MSG) archive (2004–2012). The retrieval method consists of a non-linear split-window algorithm and an algorithm correction relying on simulations of infrared brightness temperatures performed using atmospheric profiles of water vapour and temperature from a Numerical Weather Prediction model, and a radiative transfer model. The cloud mask used is the Climate SAF reprocessing of the MSG/SEVIRI archive which is consistent over the period considered. Atmospheric Saharan dust has a strong impact on the retrieved SST in the Atlantic and Mediterranean regions, they are taken into consideration through the computation of the Saharan Dust Index (SDI) which is then used to determine an empirical correction applied to SST. The reprocessing has benefited from the experience of the OSI SAF team in operational near real time processing of MSG/SEVIRI data, and the methods have been improved to provide a higher quality SST. The MSG/SEVIRI SST reprocessing dataset consists of hourly level 3 composites of sub-skin temperature projected onto a regular 0.05° grid over the region delimited by 60N,60S and 60W,60E. It has been thoroughly validated against drifting buoys and moored buoys measurements. Results of this validation have shown that the reprocessed data record is of significantly better quality than the OSI SAF operational processing (for instance the day-time robust standard deviation is 0.45 K for the operational processing and 0.35 K for the reprocessed dataset). The data record has been used to characterize the diurnal variability of SST over large temporal and spatial scales.

摘要 欧洲气象卫星开发组织 (EUMETSAT) 的海洋和海冰卫星应用设施 (OSI-SAF) 对旋转增强型可见光和红外成像仪 (SEVIRI) 的海面温度 (SST) 进行了再处理机载气象卫星第二代 (MSG) 档案（2004-2012 年）。反演方法包括非线性裂窗算法和依赖于红外亮度温度模拟的算法校正，该模拟使用来自数值天气预报模型的水汽和温度的大气廓线以及辐射传输模型进行。使用的云掩码是 MSG/SEVIRI 档案的气候 SAF 再处理，它在所考虑的时期内是一致的。大气撒哈拉尘埃对大西洋和地中海地区反演的 SST 有很大影响，通过计算撒哈拉尘埃指数 (SDI) 将它们考虑在内，然后使用该指数确定应用于 SST 的经验修正。再处理得益于 OSI SAF 团队在 MSG/SEVIRI 数据的近实时操作处理方面的经验，并且改进了方法以提供更高质量的 SST。MSG/SEVIRI SST 再处理数据集包括投影到由 60N、60S 和 60W、60E 分隔的区域上的规则 0.05° 网格上的子皮肤温度的每小时 3 级复合。它已针对漂流浮标和系泊浮标测量进行了彻底验证。此验证的结果表明，再处理数据记录的质量明显优于 OSI SAF 操作处理（例如，操作处理的日间稳健标准偏差为 0.45 K，再处理数据集的标准偏差为 0.35 K）。数据记录已被用于表征海温在大时空尺度上的日变化。
