The Refractive Index Structure Parameter/Atmospheric Optical Turbulence Model: CN2

Abstract

The CN2 model is a semi-empirical algorithm that makes a quantitative assessment of 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 added to the Electro- Optics Atmospheric Effects Library (EOSAEL). This report gives technical and user's guide information on the CN2 model.
