摘要

本文描述了在法国奥格瓦尔流域进行的一场密集的野外活动，这是NASA -欧洲91实验的一部分。基于Deardorff的形式化的两层表面能量平衡模型已经被测试和验证，以便结合光学(可见光到热红外)和主动微波数据。利用这种协同作用回收蒸发通量似乎是一种可靠的技术。进一步的工作应增加遥感参数的时空变异性，以获得它们与地表通量之间更好的物理关系。

Estimation Of Surface Fluxes Over Canopies During MAC-europe 1991 Campaign Using Combined Microwave And Optical Data

An intensive field campaign in the Orgeval watershed, France, part of the NASA MAC-Europe'91 experiment, is described. A two-layer surface energy balance model, based on Deardorff' s formalism, has been tested and validated, in order to incorporate combined optical (visible to thermal infrared) and active microwave data. Retrieving evaporation fluxes using this synergy seems to be a reliable technique. Further work should increase temporal and spatial variability of remote sensed parameters to get better physical relationships between them and surface fluxes.
