Solar radiation enters the Earth's atmosphere with a portion being scattered by clouds and aerosols.

Airborne Multi-angle Spectro Polarimetric Imager (AirMSPI) is an airborne prototype instrument similar to that of the future satellite-borne MSPI instrument for obtaining multi-angle polarization imagery. AirMSPI flies on the NASA-owned ER-2 aircraft. The instrument was built for NASA by the Jet Propulsion Laboratory in Pasadena, California.

Multiangle radiance and polarization imagery from AirMSPI will (a) provide 3-D scene context where clouds and aerosol plumes are present, plus constraints on radiometric closure, particularly over heterogeneous scenes where 3-D radiative transfer may dominate, and (b) enable retrieval of aerosol and cloud macrophysical properties (distribution, height), microphysical properties (size distribution, single scattering albedo, shape), and optical depth.
