Comparison of Atmospheric Transmittance Measurements in the 3-5 Micrometers and 8-12 Micrometers Spectral Regions With MODTRAN: Consideration for Long Path Geometries.

Abstract

Radiance measurements conducted during tropospheric operations to detect objects on the Earth's surface from a manned aircraft or from an unmanned airborne vehicle (UAV) will involve long, near-horizontal viewing geometries. The computer code MODTRAN is widely used for the prediction of the propagation of infrared radiation through the lower atmosphere. This program was undertaken by the IARD to test and validate the predictions of the MODTRAN code for the 3-5 micrometer and 8-l2 micrometer spectral regions under semi-arid desert conditions with well defined meteorological parameters.
