In 2001, the authors predicted a change of atmospheric sulfur dioxide (SO_2) concentration in China from 1992 to 2005 (as immediate future), using a multi-grid steady-state box model, coupled with an empirically derived change rate or SO_2 concentration at Chinese major cities during 1990's (1991-1999). In this study, we have verified the predicted change in the SO_2 concentrations, comparing with the observation data in 2005 as taken from the current issue of China Environmental Yearbook. The decreasing rate in observed data from 1992 to 2005 resulted in 24.6% as an average of 56 cities, whilst that in predicted values was 38.2%. This difference mostly resulted from the changes in the yearly trend of SO_2 concentration after 2000 in several cities, partly due to newly put governmental policies to boost the underdeveloped regions of China and changes of sampling site of the monitoring network.
