Abstract: 
We examined a possible nature and the origin of solar irradiance five-minute oscillations. Using solar radiation observations (DIFOS-F, VIRGO SPM, the line λ 532.418 nm Fe I of a high spatial resolution) we solved inverse radiative transfer problem and reproduced height stratification of the local and global temperature oscillations of low l in the solar photosphere. Pseudoglobal oscillations of temperature were extracted from photosphere oscillations, which enabled us to study the contribution of acoustic and internal gravity modes into the solar irradiance oscillations. It is shown that the latter ones originate probably from the scattering p-modes of low l on the solar granulation with the subsequent constructive interference.
Keywords: inverse problem, oscillations, solar
