Abstract:

The scientific aims that motivate our work on this project are 1 to understand quantitatively the multiple-scattering physics underlying spaceborne hyperspectral and lidar observations of atmospheric aerosols and surface reflectivity 2 to develop rigorous, stable i.e., genuinely useful inverse methods to interpret such observations in terms of geophysical quantities, based on the mathematics of inverse radiative transfer and 3 to apply such methods to gain otherwise unavailable insight into geophysical interactions of the ocean, the atmosphere, and land surfaces. The specific objectives of this project are 1 to understand quantitatively how the accuracy of dust parameter and ocean color estimates from hyperspectral data depend on knowledge of vertical aerosol distributions and dust particle absorption 2 to develop improved methods for estimating dust aerosol properties and water-leaving-radiance WLR from hyperspectral and limited vertical profile data, including data from the newest generations of NASA SeaWIFS, MODIS, MISR, and spaceborne lidar and DoD COISNEMO sensors and 3 to demonstrate the initial use of such methods in investigation of dust outbreaks over littoral seas.
