CHARTS results for the three  cases are stored in ASCII files as a function of wavenumber (cm^-1) or wavelength (nm).  There are separate files for each component (downward direct, downward diffuse, upward diffuse) and each solar zenith angle. Each file contains irradiances in W/m² cm^-1 (or W/m² nm) at TOA,  at the top and bottom of the cloud or at the tropopause, and at the surface. The wavenumber files are 1 wavenumber resolution, the wavelength files at 5 nm resolution. Each tar file contains all the files (by wavenumber or wavelength) for a given case.
