The Rayleigh scattering of cosmic microwave background (CMB) photons off theneutral hydrogen produced during recombination effectively creates anadditional scattering surface after recombination that encodes new cosmologicalinformation, including the expansion and ionization history of the universe. Afirst detection of Rayleigh scattering is a tantalizing target fornext-generation CMB experiments. We have developed a Rayleigh scatteringforecasting pipeline that includes instrumental effects, atmospheric noise, andastrophysical foregrounds (e.g., Galactic dust, cosmic infrared background, orCIB, and the thermal Sunyaev-Zel'dovich effect). We forecast the Rayleighscattering detection significance for several upcoming ground-basedexperiments, including SPT-3G+, Simons Observatory, CCAT-prime, and CMB-S4, andexamine the limitations from atmospheric and astrophysical foregrounds as wellas potential mitigation strategies. When combined with Planck data, we estimatethat the ground-based experiments will detect Rayleigh scattering with asignificance between 1.6 and 3.7, primarily limited by atmospheric noise andthe CIB.
