全国土壤水分观测系统数据质量分析

Soil Moisture Observation System and Date-quality Analysis in China

土壤水分观测对研究全球水循环和大气气候变化至关重要,然而由于对自动观测设备的运行监控程度以及数据质量控制算法的缺乏,导致自动观测的土壤湿度数据可用率较低。本文以我国综合观测系统运行监控平台为基础,简单阐述所设计的一套自动土壤水分运行监控系统,重点针对该系统中土壤湿度数据质量控制方法和由此产生的数据错误情况进行分析,经过数据格式检查和质量算法控制后的数据,可对单站或多站观测要素进行产品展示与分析。

The observation of soil moisture is essential for researching on global water cycle and climate change.Nevertheless,the operation monitoring of automatic observation equipment as well as the algorithm of data quality control stayed in lack,which lead the soil moisture data unavailable.This paper briefly introduced a set of automatic soil moisture observation system designed based on the integrated observation system operation monitoring platform.The emphasis was layed on the analysis of quality control method of soil moisture data and error results caused by it.After data format check and quality algorithm control,the data can be used for the product show and analysis of single and multi station.
