Local effective spectral and total emissivities of nonisothermal cavities having diffuse surfaces are evaluated. The effective emissivity of the cavity wall around the half-depth of a cylinder is little affected by a linear decrease or increase of temperature along the cavity axis because of a compensation effect. The nonisothermal effect on the integrated cavity emissivity changes considerably with cavity geometry for a given temperature distribution.
