A comparison of models for computing atmospheric infrared transmission
Abstract
In 1973 an intensive research effort called SCARP produced a unique set of infrared radiometric data to compare the performance of several atmospheric infrared radiative transfer models. The models were described in detail and were shown to differ primarily in the manner in which the transmissivities for the various gaseous constituents of the atmosphere are computed. The models were compared with observed profiles of apparent surface temperature obtained with airborne radiometers during the SCARP experiment over various test sites in the southern United States. The models were also compared with Skylab infrared spectrometric data. Error and sensitivity analyses showed that the models are quite sensitive to the moisture profile data used as input, and to the selection of surface temperature. In conclusion it was noted that aerosols do not appear to have a significant effect on the computations of infrared transmission in the window region based on SCARP data.
