This code serves as a supplement to the paper titled 'Two-year Cosmology Large Angular Scale Surveyor (CLASS) Observations: A First Detection of Atmospheric Circular Polarization at Q Band', The Astrophysical Journal, Volume 889, page 120, ADS. It simulates millimeter-wave atmospheric emission, including polarization. This emission is primarily from molecular oxygen, with emission by water vapor and the dry continuum also considered.
