Abstract

lowtran 7 and modtran were evaluated in the 2.0–5.5-μm region against field-collection data at high zenith angles and long path lengths to determine the degree of uncertainty associated with these models under these conditions. Matching data sets were developed with data from the U.S. Air Force Geophysics Laboratory's Flying Infrared Signatures Technology Aircraft (FISTA) as the field reference. The percent difference between the model and the field data was determined. Agreement between the model and the field data was found to be better than 97% for most cases. Median percent difference was within 10% for zenith angles less than 90°.
