Abstract : This interim report summarizes the work done in the first two months of the contract period. The objective was to evaluate different methods proposed for the measurement of atmospheric transmittance with AGA 780 camera. Simultaneously, a computerized formulation was prepared for the data analysis of the output of the AGA system (the data link). A first field test was performed over a range of 400m. As a result of this experiment a calibration procedure, which is needed for the measurement of an absolute (integrated) atmospheric transmittance, was established. This procedure is needed to further evaluation of the measurement methods.
