SPRINTARS (Spectral Radiation-Transport Model for Aerosol Species) is a numerical model which has been developed for simulating effects on the climate system and condition of atmospheric pollution by atmospheric aerosols on the global scale.

SPRINTARS is based on an atmosphere-ocean general circulation model, MIROC, developed by Atmosphere and Ocean Research Institute (Division of Climate System Research), University of Tokyo, National Institute fot Environmental Studies, and Japan Agency for Marine-Earth Science and Technology (Research Institute for Global Change), and treats main tropospheric aerosols both from natural and anthropogenic sources (black carbon, organic matter, sulfate, soil dust, and sea salt). They are also categorized into SPM, PM10 and PM2.5. SPRINTARS calculates transport processes of aerosols (emission, advection, diffusion, wet deposition, dry deposition, and gravitational settling). The aerosol direct effect, which is scattering and absorption of solar and thermal radiation by aerosols, and the indirect effect, which is act of aerosols as cloud condensation nuclei and ice nuclei, are included in the calculation.
