摘要:

当前,以全球、区域(流域)为单元建立分布式的观测网已成为陆地表层系统观测的主流方向,而良好的运行与维护、严格的数据质量控制是获取高质量观测数据的前提。本文以中国第二大内陆河黑河流域为例,概述了黑河流域地表过程综合观测网的相关情况,总结了该观测网的运行与维护以及数据质量控制的研究进展,主要包括:日-旬-月-年尺度的运行与维护流程,由仪器比对与标定、数据处理、筛选与审核等构成的数据质量控制流程等。以2018年3个超级站为例展示了观测数据成果,并介绍了黑河流域地表过程综合观测网的成效。本文的研究成果将对“丝绸之路经济带”上许多相近内陆河流域的野外观测与数据质量控制等工作起到借鉴作用。

Abstract:

Distributed observatory network connects global and regional field sites, which is one of the prerequisites in earth surface processes observation. It is a priori to keep proper operation and maintenance, and perform strict data quality control for obtaining high-quality observation data. The current study took the Heihe River Basin (HRB), the second largest endorheic basin in China, as an example to introduce the research progress of the site maintenance and data quality control of the Heihe integrated observatory networks. The introduction of the operation and maintenance procedure covers daily, 10-day, monthly, and annual time intervals; while the data quality control process consists of instrument comparison and calibration, data processing, screening and checking, among others. Taking three superstations as an example, the observation data in 2018 are presented. Finally, the achievements of the Heihe integrated observatory network are introduced. The results can serve as a reference for the field observation and data quality control of the endorheic basins along the “Silk Road Economic Belt”.
