Summary The purpose of this effort is to develop and integrate models and databases that provide realistic environmental characterizations derived from gridded COAMPS(R) forecast fields for electro-optical system performance predictions. These environmental characterizations include vertical profiles of refractivity and optical turbulence (Cn2) which extend from the surface upward throughout the troposphere. The NAVSLaM model will be modified to produce near-surface profiles of refractivity and optical turbulence (Cn2) for optical through mid-infrared wavelengths (0.3 to 20 microns). Upper-air Cn2 models will be evaluated and the best candidate will be selected, modified as necessary, and integrated into the EO performance prediction system. A model for blending the near-surface and upper-air Cn2 profiles will be developed. The new BO-capable NAVSLaM and the Cn2 blending algorithm will be submitted to the Oceanic and Atmospheric Master Library (OAML). EO modeling studies will be performed with HELEEOS to test the new atmospheric characterizations of refractivity and Cn2 to validate their suitability and determine the value-added and identify areas that need further improvement.
