2015年11月，荧光探测器（FLEX）被选为欧洲航天局的第八个地球探测器使命。串联使命概念将提供光谱和空间分辨率的测量，从而能够检索和解释陆地植被发出的全部叶绿素荧光光谱。本文提供了一个使命概念概述的科学目标，与荧光相关的关键目标，并要求保证健身为目的的科学数据集。我们在选择时提出使命设计，即，在项目A/B1阶段结束时，由两个独立的工业财团开发。这两个使命概念都依赖于一个单一的有效载荷荧光成像光谱仪，覆盖500至780纳米的光谱范围。在氧吸收带中，其光谱分辨率为0.3 nm，光谱采样间隔为0.1 nm。光谱仪的扫描带宽度为150公里，空间分辨率为300 x 300米（2）。该卫星将与哨兵-3号一起飞行，提供不同和互补的测量，时间为6至15秒。FLEX计划于2022年发射。
In November 2015, the FLuorescence EXplorer (FLEX) was selected as the eighth Earth Explorer mission of the European Space Agency. The tandem mission concept will provide measurements at a spectral and spatial resolution enabling the retrieval and interpretation of the full chlorophyll fluorescence spectrum emitted by the terrestrial vegetation. This paper provides a mission concept overview of the scientific goals, the key objectives related to fluorescence, and the requirements guaranteeing the fitness for purpose of the resulting scientific data set. We present the mission design at the time of selection, i.e., at the end of project phase Phase A/B1, as developed by two independent industrial consortia. The mission concepts both rely on a single payload Fluorescence Imaging Spectrometer, covering the spectral range from 500 to 780 nm. In the oxygen absorption bands, its spectral resolution will be 0.3 nm with a spectral sampling interval of 0.1 nm. The swath width of the spectrometer is 150 km and the spatial resolution will be 300 x 300 m(2). The satellite will fly in tandem with Sentinel-3 providing different and complementary measurements with a temporal collocation of 6 to 15 s. The FLEX launch is scheduled for 2022.
