Cairns, B., F. Waquet, K. Knobelspiesse, J. Chowdhary, and J.-L. Deuzé, 2009: Polarimetric remote sensing of aerosols over land surfaces. In Satellite Aerosol Remote Sensing over Land. A.A. Kokhanovsky and G. De Leeuw, Eds., Springer-Praxis Books in Environmental Sciences, Springer, pp. 295-325, doi:10.1007/978-3-540-69397-0_10.

There are three facets to the use of downward-looking polarimetric measurements for the remote sensing of aerosols over land surfaces. A method for the measurement of the polarization of the scene being observed, a quantitative model of the polarized reflectance behavior of the underlying surface and an understanding of what aspects of the aerosol loading, microphysics and vertical distribution are revealed in the polarization signal. This chapter is therefore organized as follows. In Section 2 we provide a brief review of the different instrumental approaches that have been taken to the Earth viewing measurement of polarization. This review focuses on the benefits and issues related to these measurement techniques with particular regard to their use over land. In Section 3 we summarize the conclusions that have been drawn in the existing literature related to the polarized reflectance of land surfaces and discuss how various modeling approaches, that can be used in remote sensing applications, take advantage of the polarized behavior of the surface. Although single scattering models of the polarized light reflected by the atmosphere-surface system of the Earth have been used with considerable success, when measurements are of sufficient accuracy, or extend into the blue, or ultraviolet spectral domain it is not sufficient to use such an approach for the modeling of the observed polarized radiances. In Section 4 we therefore describe how the land surface-atmosphere system can be modeled with different levels of fidelity depending on the accuracy and spectral domain of the measurements that are available. In Section 5 we review existing retrieval methods and discuss how optimal methods can be applied in the case of polarimetric remote sensing. In particular we emphasize the capability provided by the extended spectral range and more accurate measurements that are currently available in airborne polarimeters and are expected to be available in future spaceborne instruments.
