Abstract
Experimental measurements of infrared transmittance are reported, which show that the computer code LOWTRAN-4 predicts too high a transmittance in the region 4.3 to 5.5 microns, and that the discrepancy is dependent on the water-vapor content. We have carried out experiments at various ranges up to 45 km in order to vary the precipitable water amount over a wide range, and, from the results, we have deduced that the anomalous transmittance results from an incorrect estimate of the continuum absorption, while the spectral component is substantially correct.
