Coupled surface-atmosphere reflectance (CSAR) model 2 : Semiempirical surface model usable with NOAA advanced very high resolution radiometer data
A semiempirical model to describe the bidirectional reflectance of arbitrary natural surfaces using only three parameters has been developed. This model accounts for the observed variability of reflectance measurements in laboratory and field conditions, ranging from bare soil to full canopy cover, in both the visible and the near-infrared bands. Coupled with a simple atmospheric radiation transfer model, it has been inverted against NOAA/AVHRR data from several desert sites in northern Africa. This procedure allows the retrieval of surface properties and average amounts of atmospheric constitutents (aerosol optical thickness and water vapour) for the duration of the measurement period. The feasibility of inverting a coupled surface-atmosphere model against existing AVHRR data is demonstrated and the current limits of this approach are documented.
