Abstract:

This study investigates the radiative transfer code, Laser Environmental Effects Definition and Reference LEEDR, developed by the Center for Directed Energy at the Air Force Institute of Technology. Many multi- and hyperspectral applications are limited to the nighttime due in large part to daytime solar background noise and it is advantageous to be able to quantify this background noise using LEEDR. Real-time meteorological MET surface observations, numerical weather prediction NWP, and aerosol particle concentrations were used to investigate the accuracy of LEEDR radiances simulations. Comparisons between simulations and measured values show that aerosol concentrations, weather predictions, and meteorological observations provide enough information to nearly duplicate real-time measured sky radiances.
