A computer program which is called AIRCAP and calculates atmospheric path transmission and thermal radiation in the 8-25 micron spectral region is described. After a brief review of atmospheric absorption properties and atmospheric band model transmission calculations, AIRCAP's calculational procedures are outlined. Comparison of AIRCAP's predictions and several data samples are made. The agreement is considered quite good.
