CHAPTER 6

Estimation of Physical Parameters

This chapter revises the main problems and methods used in the field of model inversion and estimation of physical parameters from remotely sensed images. The number and accuracy of current methods (either physically-based inversion, statistical methods or combined approaches) has made possible the prediction of atmospheric parameters, crop characteristics, and ocean state.

6.1 INTRODUCTION AND PRINCIPLES

The main goal of optical Earth Observation is to monitor the Earth and its interaction with the atmosphere. The analysis can be done at local or global scales by looking at bio-geo-chemical cycles, atmospheric situations and vegetation dynamics [Liang, 2004, 2008, Lillesand et al., 2008, Rodgers, ...
