Refractive Index Structure Parameter/Atmospheric Optical Turbulence Model: CN2

摘要

The CN2 model is a semi-empirical algorithm that makes a quantitative assessmentof atmospheric optical turbulence. The algorithm uses surface layer gradient assumptions applied to two levels of discrete vertical profile data to calculate the refractive index structure parameter. Model results can be obtained for unstable, stable, and near-neutral atmospheric conditions. The CN2 model has been benchmarked on data from the REBAL'92 field study. The model will shortly be
