TL;DR: In this article, a simple algorithm to retrieve sail moisture and vegetation water content from passive microwave measurements is analyzed, based on a zeroth-order solution of the radiative transfer equations in a vegetation layer.

TL;DR: In this paper, a coupling strategy between well known and validated crop functioning and radiative transfer models (RTM), applied to wheat crops, is presented. But the coupling is performed through several state variables: leaf area index, leaf chlorophyll content, organ dry matter and relative water content, and the coupling scheme is then tested on the data set provided by the Alpilles-ReSeDA campaign.

TL;DR: In this paper, the capability of model inversion to retrieve the leaf area index (LAI) of wheat, maize, sunflower and alfalfa crops, for which ground validation was available, was evaluated.

TL;DR: A catalogue of donnees de reflectance bidirectionnelle (BRDF), acquis avec le capteur aeroporte POLDER, correspondant a plusieurs types de cultures (principalement du ble, de la luzerne, du tournesol et du mais) a ete acquis lors de la campagne Alpilles/ReSeDA, tout au long des cycles de cultures en 1997 as discussed by the authors.

TL;DR: In this article, the use of SPOT satellite data for deriving crop biophysical parameters at various dates during the growing season was described, in particular, the leaf area index (LAI) was estimated by using the semi-empirical CLAIR model.
