Title: Evaluation of LOWTRAN and MODTRAN for use over high zenith angle/long path length viewing
Author: Wright, Jonathan
Abstract: LOWTRAN and MODTRAN were evaluated in the 2.0-5.5 micron region against field collection data at high zenith angle/long path lengths to determine the degree of uncertainty associated with these models under these conditions. Matching data sets were developed using data from the Air Force Geophysics Laboratory Flying Infrared Signatures Technology Aircraft (FISTA) as the field reference. The Kolmogorov-Smirnov test was applied to determine the degree to which the outputs of LOWTRAN and MODTRAN follow the same distribution as the field data. The percent difference between the model and field data was also studied. Agreement between the model and field data was found to be better than 97% for most cases. Median percent difference was within 10% for zenith angles less than 90 degrees.
