Abstract

According to the transport characteristics of PM2.5 and adjoint assimilation scheme, a PM2.5 adjoint assimilation model was constructed. Two ideal distributions of PM2.5 initial field were prescribed by the pollution condition of Chinese mainland. Experiment results indicated that mean absolute errors (MAEs) of observations and inverted results, and MAEs of inversion results and prescribed distribution decreased greatly after assimilation. The inversion results were also nearly equal to the prescribed distributions, indicating that this model could efficiently invert the PM2.5 initial field. Besides, the inversion efficiency could be raised if ratio of effective observations was increased.
