Abstract : This document supplements a briefing on Uncertainties in the Prediction of High-Altitude Nuclear Effects. The intended audience consists of the SDS architects and engagement modelers who have to consider the nuclear (and other) environment but are under very severe constraints regarding computer running time so that very fast-running and thus simple models of atmospheric environment have been used. This material is a tutorial, intended to give the audience a physical feeling of the nature of the natural and nuclear endoenvironment (i.e., environments and heights of burst in the 0-100-km altitude range), pointing out the changes in nuclear phenomenology at different altitudes and the large variabilities in the natural atmosphere, including effects of turbulence, clouds, and rain. The factors to be considered for SDS modeling depend on the threat scenario under consideration, such as the number, altitude and yield of the nuclear bursts, and the nature of sensors under consideration (IR, UV/VIS, MMW; spectral and spatial resolution; sensitivity; active vs. passive sensors).
