This is a final report on Avco Everett Research Laboratorys study on Boundary Layer Interference Calculations. In the program the infrared radiation from 3 - 20 microns emanating from the ablating boundary layer of a reentering vehicle was calculated down to 100 kft. It was found that the radiation was dominated by ambient CO2 and H2O and air shock produced NO down to 150 kft at which altitude ablation product radiation began to become important. The results of these calculations were compared with various sources of earth radiation including earth surface, atmosphere, and scattered sunlight. CO radiation at 4.3 microns from the boundary layer was found to have a higher radiance than the earth at 100 kft.
