蒸散（ET）是地表（植被、土壤和水体）与大气之间的水通量。监测这种水分流失对于水文学、农业、水利用效率研究和干旱监测等方面的应用可能至关重要。我们介绍了几个卫星为基础的业务蒸散产品之一，在欧洲，非洲和南美洲的一部分，连续和近实时生成。欧洲气象卫星应用组织的陆地表面分析卫星应用设施业务中心（http：//www.example.com）生成ET产品（每天30分钟）。landsaf.ipma.pt根据我们对用户社区的承诺，我们不断寻找新的方法来改进产品。为了实现这一点，来自产品的用户和潜在用户的反馈非常重要。在这方面的贡献，我们提出的ET产品的特点和最近的改进，由于纳入我们的ET算法的新变量来自地球观测的MSG SEVIRI。我们展示了ET产品的例子，并强调了它们在干旱检测和监测方面的潜力。一些可能的应用的例子，邀请用户和研究人员探讨LSA-SAF蒸散产品提供的可能性。
Evapotranspiration (ET) is the flux of water between the surface (vegetation, soil and water bodies) and the atmosphere. Monitoring this water loss may be of crucial importance for applications in hydrology, agriculture, water use efficiency studies and drought monitoring. We introduce one of the few satellite-based operational evapotranspiration products, generated continuously and in near real-time over Europe, Africa and part of South America. The ET products (30 minutes and daily) are generated at the EUMETSAT’s Satellite Application Facility on Land Surface Analysis (LSA-SAF) operations centre (http://landsaf.ipma.pt). Following our commitments to our user’s community, we are continuously looking for new ways to improve the product. To accomplish this, the feedback from users and potential users of the products is of great interest. In this contribution we present the ET products characteristics and recent improvements gained thanks to the inclusion in our ET algorithm of new variables derived from Earth observation by MSG SEVIRI. We show examples of the ET products and we highlight their potential in droughts detection and monitoring. Some examples of possible applications are presented to invite users and researchers to explore the possibilities offered by LSA-SAF evapotranspiration products.
