Seasonal variation of sulfur transport and budgets in East Asia

Using our 3-D long range transport handy model, we calculated and analyzed the quantity of sulfur transporting across the boundary of different countries and regions in East Asia. On the basis we discussed the budgets of sulfur and its seasonal variation on input, deposition and remnants for each country. It is shown the deposition is less than emission and the outputs are larger than the inputs in most countries of East Asia except North Korea. There are higher concentration of sulfur and more pollutants transported out of China in winter than those in summer.
