The objective of this program was to perform a coordinated research effort employing complementary electro-optical techniques to characterize optical and infrared propagation through the atmosphere. This effort included measurements of the parameters that affect propagation, at several wavelengths, under meteorological conditions of interest to DoD. Under this program we performed acquisition, reduction and interpretation of data using lidar techniques (both coherent and incoherent) and visible and infrared transmissometry. This included: ...
