CM SAF Land SUrface Temperature dataset from METeosat First and Second Generation - Edition 1 (SUMET Ed. 1)

This Thematic Climate Data Record (TCDR) provides Land Surface Temperature (LST) derived from the Meteosat Visible and InfraRed Imager (MVIRI) on board the Meteosat First Generation (MFG) and the Spinning Enhanced Visible and InfraRed Imager (SEVIRI) onboard the Meteosat Second Generation (MSG) satellites. The covered time period ranges from January 1991 to December 2015, thus includes MFG 4 to 7 and MSG 1 to 3. Original thermal radiances were inter-calibrated by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) using the High Resolution Infrared Radiation Sounder (HIRS) as a reference.
The LST is derived from Meteosat by use of single-channel LST retrieval algorithms suitable to generate LST data across Meteosat satellite generations. This TCDR includes two different LST products: the Statistical Land Surface Temperature product generated with a statistical LST retrieval approach and a Physical Land Surface Temperature product based on radiative transfer calculations. The LST is presented as hourly data and as monthly averaged diurnal cycle composites on a 0.05°x0.05° grid covering the entire Meteosat disk (Africa and Europe).
A summary of the retrieval algorithms is provided by Duguay–Tetzlaff et al. 2015. Along with the data, a comprehensive documentation including user guide, algorithm descriptions and extensive validation studies, is given.

本专题气候数据记录（Thematic Climate Data Record, TCDR）提供地表温度（Land Surface Temperature, LST）数据，此类数据由搭载于静止气象卫星第一代（Meteosat First Generation, MFG）的可见红外成像仪（Meteosat Visible and InfraRed Imager, MVIRI），以及静止气象卫星第二代（Meteosat Second Generation, MSG）的旋转增强型可见红外成像仪（Spinning Enhanced Visible and InfraRed Imager, SEVIRI）所获取。数据集覆盖时段为1991年1月至2015年12月，涵盖MFG 4至7号卫星与MSG 1至3号卫星的观测数据。原始热辐射数据由欧洲气象卫星开发组织（European Organisation for the Exploitation of Meteorological Satellites, EUMETSAT）以高分辨率红外辐射探测仪（High Resolution Infrared Radiation Sounder, HIRS）为参考基准完成交叉定标。
本数据集通过适配多代静止气象卫星的单通道地表温度反演算法，从静止气象卫星观测数据中反演得到地表温度。本专题气候数据记录包含两类地表温度产品：一类为采用统计反演方法生成的统计型地表温度产品，另一类为基于辐射传输计算得到的物理型地表温度产品。地表温度数据以逐小时格式发布，同时还包含以0.05°×0.05°分辨率网格生成的月均日循环合成数据，覆盖完整静止气象卫星视场范围（非洲与欧洲区域）。
反演算法的详细概述可参见Duguay-Tetzlaff等（2015）的研究成果。随数据集一同发布的还有全面的文档资料，涵盖用户指南、算法说明以及多维度验证研究内容。
