Relationship between surface reflectance in the visible and mid-IR used in MODIS aerosol algorithm - theory
TL;DR: In this article, the authors used a model to describe the transfer of radiation through a vegetation canopy composed of randomly oriented leaves to assess the theoretical foundations for these relationships, and concluded that the value of this ratio should ideally be made dependent on the land cover type in the operational processing of MODIS data.

Empirical TOMS index for dust aerosol: Applications to model validation and source characterization
TL;DR: In this article, an empirical relation is developed to express the total ozone mapping spectrometer (TOMS) aerosol index (AI) for the case of dust plumes, as an explicit function of four physical quantities: the single scattering albedo, optical thickness, altitude of the plume and surface pressure.
