Works, Software and Database
2. To research effects of aerosols on the climate system and to simulate condition of air pollution, the SPRINTARS (Spectral Radiation-Transport Model for Aerosol Species) has been developed. The SPRINTARS is a global three-dimensional aerosol transport-radiation model coupled with the CCSR (Center for Climate System Research, University of Tokyo)/NIES (National Institute for Environmental Studies, Japan)/FRCGC (Frontier Research Center for Global Change) AGCM (Atmospheric General Circulation Model). he treated aerosol species and their precursors are main tropospheric aerosols and related gases. The aerosol transport processes include emission, advection, diffusion, and deposition (sub-cloud scavenging, in-cloud scavenging, dry deposition, and gravitational settling). The model can treat nudging of the meteorological parameters of wind, temperature, and specific humidity with reanalysis data. The radiative process is calculated considering refractive indices depending on wavelengths, size distributions, and hygroscopic growth of each aerosol species. Changes in cloud droplet size (1st indirect effect) and precipitation (2nd indirect effect) are included in the model. SPRINTARS is also able to simulate climate change due to aerosols with feedback mechanisms by coupled with the ocean or mixed layer ocean model.
