Walnut Gulch Experimental Watershed site, station Flume 104, study of mean daily streamflow in units of litersPerSecond 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 Walnut Gulch Experimental Watershed (WGE)
contains mean daily streamflow measurements in litersPerSecond units
and were aggregated to a monthly timescale.

EcoTrends项目由黛布拉·彼得斯博士（约尔纳达盆地长期生态研究站，美国农业部农业研究服务局（USDA-ARS）约尔纳达实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究站，美国农业部林务局（USDA-FS）卢奎洛实验森林）于2004年创立，旨在支撑长期生态数据集的收集与分析工作。该项目是一项大型综合研究项目，核心聚焦于提升长期数据的可获取性与使用效率。目前共有约50个州级与联邦资助的研究站点参与并为EcoTrends项目贡献数据，其中包含全部26个长期生态研究（Long-Term Ecological Research, LTER）站点，以及美国农业部农业研究服务局（USDA Agriculture Research Service, ARS）、美国农业部林务局、美国能源部、美国地质调查局（US Geological Survey, USGS）资助的站点与众多高校站点。EcoTrends项目的数据可通过探索性网络门户（http://www.ecotrends.info）获取。该网络门户依托交互式网页应用，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络溯源感知综合跟踪架构（LTER Provenance Aware Synthesis Tracking Architecture, 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。该网络门户由约尔纳达长期生态研究站与长期生态研究网络办公室合作开发。以下来自核桃谷实验流域（Walnut Gulch Experimental Watershed, WGE）的数据集包含以升每秒为单位的日均径流量测量值，且已被聚合至月度时间尺度。
