Fort Keogh site, station Fort Keogh Lysimeter 6, study of soil moisture at a depth of 60 centimeters in units of percent on a monthly timescale

The EcoTrends project was established in 2004 by Dr. Debra Peters
(Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and
Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest)
to support the collection and analysis of long-term ecological datasets.
The project is a large synthesis effort focused on improving the accessibility
and use of long-term data. At present, there are ~50 state and federally funded
research sites that are participating and contributing to the EcoTrends project,
including all 26 Long-Term Ecological Research (LTER) sites and sites funded by
the USDA Agriculture Research Service (ARS), USDA Forest Service,
US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal
(http://www.ecotrends.info). This web portal enables the continuation of data
compilation and accessibility by users through an interactive web application.
Ongoing data compilation is updated through both manual and automatic
processing as part of the LTER Provenance Aware Synthesis Tracking
Architecture (PASTA). The web portal is a collaboration between the Jornada LTER
and the LTER Network Office. The following dataset from Fort Keogh (FTK)
contains soil moisture at a depth of 60 centimeters measurements in percent units
and were aggregated to a monthly timescale.

EcoTrends项目由黛布拉·彼得斯博士（约那盆地长期生态研究网[Long-Term Ecological Research，缩写LTER]，美国农业部农业研究局约那试验牧场）与阿里尔·卢戈博士（卢奎约长期生态研究网[LTER]，美国农业部林务局卢奎约试验林）于2004年创立，旨在支撑长期生态数据集的采集与分析工作。该项目为一项大型综合研究工作，核心目标是提升长期生态数据的可获取性与应用价值。目前共有约50个由州级与联邦政府资助的研究站点参与EcoTrends项目并贡献数据，其中涵盖全部26个长期生态研究（LTER）站点，以及美国农业部农业研究局（ARS）、美国农业部林务局、美国能源部、美国地质调查局（USGS）与众多高校资助的研究站点。EcoTrends项目的数据集可通过探索性网络门户（http://www.ecotrends.info）获取。该门户依托交互式Web应用程序，支持用户持续开展数据汇编与数据获取工作。作为长期生态研究网溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture，缩写PASTA）的组成部分，持续推进的数据汇编工作通过手动与自动两种处理方式完成更新。该网络门户由约那LTER与LTER网络办公室联合开发运营。以下来自福特基奥（FTK）的数据集包含以百分比为单位的60厘米深度土壤湿度测量值，且已聚合至月度时间尺度。
