Abstract: The AF anticipates fielding the ABL in the near future and needs to account for all the atmospheric conditions, such as cloud crystals, which would impede its successful operation. The objective of this additional work basic research effort is to provide additional characterization of the optical properties of cirrus clouds (particularly the ice crystals which form within these clouds at night) together with an improved prediction of the deleterious reflections these crystals provide of laser beams which propagate through them. The PI and his team will analyse the data collected from several new experimental campaigns and then improve/update their laser beam propagation simulation code in light of this analysis.
