LONG-TERM GOALS. The scientific aims of this project are to investigate, develop, and apply methods based solidly on scattering physics and inverse theory to estimate vertical distributions of water vapor and aerosol properties from hyperspectral observations of scattered sunlight. We seek especially to advance methods for the lower troposphere, where water vapor and aerosols are concentrated and affect naval systems most strongly. We are working on distinct methods applicable over the ocean and over coast land. OBJECTIVES. Our immediate objectives are 1 to quantify the invertibility of hyperspectral e.g., NEMOCOIS data over land for water vapor profile information, based on the temperature and therefore altitude dependence of water vapor absorption lines, and to test inversion schemes using existing airborne data as warranted and 2 to develop a method to estimate lower tropospheric water vapor profile parameters over the ocean based on hyperspectral observation and clear-air aerosol scattering.
