Research Progress on Atmospheric Sulfur Cycle Model

We summarized the basic contents and the applicable conditions of typicalatmospheric sulfur cycle models, especially the classical atmospheric sulfur cycle model and the independent sulfur cycle model which is based on OsloCTM2 model.We introduced atmospheric sulfur cycle models which are coupled with some general circulation models such as ECHAM, LMDZ, CSIRO, MASINGAR, RCA2, NICAM and MIROC. Although there are many kinds of atmospheric sulfur cycle models, there are still some problems such as lack of relevant data support, comprehensive consideration of chemistry, radiation and dynamics, and interdisciplinary integrated research in the study of sulfur cycle models. To solve these problems, we proposed to optimize the quality of atmospheric sulfur emission and observation data, establish a shared database system, formulate relevant database usage regulations, strengthen the cooperation and resource sharing among subjects, and establish comprehensive high-resolution atmospheric sulfur cycle models.
