LBA-ECO LC-02 WATER TABLE FLUCTUATIONS, CATUABA UFAC PLOT, ACRE, BRAZIL: 1999-2004

This data set reports bi-weekly or monthly depth-to-water measurements for three wells located in a ~1,500 ha forest fragment on the Catuaba Experimental Farm, which is the property of the Federal University of Acre, Brazil. Data were collected between February 1999 and December 2004. There is one comma-delimited ASCII data file with this data set.

DATA QUALITY STATEMENT: The Data Center has determined that there are questions about the quality of the data reported in this data set. The data set has missing or incomplete data, metadata, or other documentation that diminishes the usability of the products.

KNOWN PROBLEMS: The depth-to-water measurements for the three wells lack ground surface elevation reference points, therefore, the groundwater table elevation for the site cannot be determined. The depth-to-water measurements are of limited use unless paired with other site data for precipitation, tree growth, etc.

本数据集记录了巴西阿克雷联邦大学所属卡图巴试验农场内一片约1500公顷的森林片段中3口监测井的每两周或月度地下水埋深测量数据。数据采集时段为1999年2月至2004年12月，配套包含1个逗号分隔的ASCII格式数据文件。

数据质量声明：本数据中心判定，本数据集所刊载的数据存在质量争议；且数据集存在缺失或不完备的数据、元数据及其他文档，这将削弱相关产品的可用性。

已知问题：3口监测井的地下水埋深测量数据缺少地面高程基准点，因此无法确定该研究站点的地下水位高程。除非结合降水、树木生长等其他场地配套数据，否则本次地下水埋深测量数据的应用价值较为有限。
