Comparison between backscattered TerraSAR signals and simulations from the radar backscattering models IEM, Oh, and Dubois [PDF]
, 2011 The objective of this paper is to evaluate on bare soils the surface backscattering models IEM, Oh, and Dubois in X-band. This analysis uses a large database of TerraSAR-X images and in situ measurements (soil moisture and surface roughness).

ORGEval: Graph-Theoretic Evaluation of LLMs in Optimization Modeling
Formulating optimization problems for industrial applications demands significant manual effort and domain expertise. While Large Language Models (LLMs) show promise in automating this process, evaluating their performance remains difficult due to the absence of robust metrics.

Improving evapotranspiration in a land surface model using biophysical variables derived from MSG/SEVIRI satellite [PDF]
, 2012 Monitoring evapotranspiration over land is highly dependent on the surface state and vegetation dynamics. Data from spaceborn platforms are desirable to complement estimations from land surface models.
