Fort Keogh site, station Fort Keogh Lysimeter 10, study of soil moisture at a depth of 15 centimeters in units of percent on a yearly 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 15 centimeters measurements in percent units
and were aggregated to a yearly timescale.

EcoTrends项目由黛布拉·彼得斯博士（Jornada盆地长期生态研究网、USDA-ARS Jornada实验牧场）与阿里尔·卢戈博士（Luquillo长期生态研究网、USDA-FS Luquillo实验林）于2004年创立，旨在支持长期生态数据集的采集与分析工作。该项目为大型综合研究项目，致力于提升长期生态数据的可及性与应用价值。目前已有约50个州立及联邦资助的研究站点参与并贡献数据至EcoTrends项目，其中包括全部26个长期生态研究（Long-Term Ecological Research，LTER）站点，以及由美国农业部农业研究服务局（ARS）、美国农业部林务局、美国能源部、美国地质调查局（USGS）及众多高校资助的站点。EcoTrends项目的数据可通过探索性网络门户（http://www.ecotrends.info）获取。该网络门户通过交互式网页应用，支持用户持续开展数据整合与提升数据可及性的工作。作为LTER溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture，PASTA）的组成部分，持续进行的数据整合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Jornada LTER与LTER网络办公室联合开发。本次提供的Fort Keogh（FTK）数据集包含以百分比为单位的15厘米深度土壤湿度测量数据，且已按年度时间尺度进行聚合。
