ABSTRACT
Using observations from two remote sites during July 2004 to March 2005, we show that at Akdala (AKD, 47 degrees 06' N, 87 degrees 58' E, 562 m asl) in northern Xinjiang Province, there were high wintertime loadings of organic carbon (OC), elemental carbon (EC), and water-soluble (WS) SO4(2-), NO3(2-), and NH4+, which is similar to the general pattern in most areas of China and East Asia. However, at Zhuzhang (ZUZ, 28 degrees 00' N, 99 degrees 43' E, 3,583 m asl) in northwestern Yunnan Province, the aerosol concentrations and compositions showed little seasonal variation except for a decreasing trend of OC from August to autumn-winter. Additionally, the OC variations dominated the seasonal variation of PM10 (particles
