2002年7月与美国合作，在1号冰川4130米积累区建立了雪冰过程观测取样定位场。连续的观测采样工作于同年9月开始。采样频率为每周一次，表层雪样品取自雪坑顶部表层5cm处（包括新雪和沉积作用后的雪），整个雪坑中以每10cm间距取样。样品分析工作于天山冰川站实验室内完成，分析每个样品中主要的阴阳离子、PH值、电导率、粉尘等。2002年至今共采集样品4000余个，已分析2500多个。其余样品的分析工作正在进行中。

The continuous observation and sampling work began in September of the same year. The sampling frequency is once a week. Surface snow samples are taken from the top 5cm of the snow pit (including new snow and deposited snow), and samples are taken every 10cm in the entire snow pit. The sample analysis work was completed in the laboratory of Tianshan Glaciological Station, analyzing the main anions and cations, pH value, conductivity, dust, etc. in each sample. Since 2002, more than 4000 samples have been collected and over 2500 have been analyzed. The analysis of the remaining samples is currently underway
