摘要

地球表面与大气之间的能量和水通量交换对一系列影响人类生活的过程至关重要。值得注意的例子包括农业产量、水的可用性、干旱的强度和范围以及生态系统为社会提供服务的能力。这些过程的相关性促使陆地表面分析卫星应用设施(LSA SAF)方案建立了一个业务框架,以根据气象卫星第二代(MSG)卫星的观测结果估算蒸散量(ET)和地表能量通量(SEF)等变量。LSA SAF 计划最近在最新版算法和同源强迫数据集的基础上启动了蒸散发和地表能量通量数据集的再处理工作。本文主要介绍由此产生的 ET/SEF 数据集,该数据记录涵盖了从 MSG 卫星运行寿命开始(2004 年)到 2020 年这段时间,并覆盖了 MSG 卫星的视场(即欧洲、非洲和南美洲东部)。此外,还提供了驱动 ET/SEF 估计的算法和数据集详情以及质量评估。

The exchange of energy and water fluxes between the Earth's surface and the atmosphere is crucial to a series of processes that impact human life. Noteworthy examples are agriculture yields, water availability, intensity and extent of droughts and the ability of ecosystems to provide services to society. The relevance of these processes has motivated the Satellite Application Facility on Land Surface Analysis (LSA SAF) programme to set up an operational framework to estimate—among other variables—evapotranspiration (ET) and surface energy fluxes (SEF) on the basis of observations by the Meteosat Second Generation (MSG) satellite. The LSA SAF programme has recently launched the reprocessing of the ET and SEF datasets on the basis of the most recent version of the algorithm and homogenous forcing datasets. This article features the resulting ET/SEF dataset, a Data Record that encompasses the period from the start of the operational life of the MSG satellite (2004) till 2020 and covers the field of view of the MSG satellite (i.e. Europe, Africa and Eastern South America). Details on the algorithm and the datasets driving the ET/SEF estimates are also provided as well as a quality assessment.

期刊介绍: Geoscience Data Journal provides an Open Access platform where scientific data can be formally published, in a way that includes scientific peer-review. Thus the dataset creator attains full credit for their efforts, while also improving the scientific record, providing version control for the community and allowing major datasets to be fully described, cited and discovered. An online-only journal, GDJ publishes short data papers cross-linked to – and citing – datasets that have been deposited in approved data centres and awarded DOIs. The journal will also accept articles on data services, and articles which support and inform data publishing best practices. Data is at the heart of science and scientific endeavour. The curation of data and the science associated with it is as important as ever in our understanding of the changing earth system and thereby enabling us to make future predictions. Geoscience Data Journal is working with recognised Data Centres across the globe to develop the future strategy for data publication, the recognition of the value of data and the communication and exploitation of data to the wider science and stakeholder communities.
