Math Model for Prediction of Infrared Signatures.

Abstract

This report covers the development and implementation of math model for use in predicting surface temperature of natural and man-made features. The model utilizes time-varying environmental inputs as well as constant thermal parameters to calculate time-varying surface temperature profiles. Formulations describe solar, conductive, radiative, convective, rain and evaporative effects on air/surface boundary. Finite difference methods are used to calculate time-varying temperature of feature surfaces. Features may be elevated or coincident with Earth's surface. Temperature or radiance from vegetative growth may also be predicted. Model has been programmed and is operational in laboratory. Model will be incorporated into an overall laboratory program for test and validation which will commence September 1981 and, as currently scheduled, continue over a 3-year period. Preliminary validation has been obtained using available sample data inputs. Validation at present is limited, based on data availability, to dry season only. (Author)
