Glacier Lakes Ecosystems Experiments Site site, station NADP Station WY00, Snowy Range, WY, study of chloride in precipitation (volume-weighted concentration) in units of milligramsPerLiter 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 Glacier Lakes Ecosystems Experiments Site (GLA)
contains chloride in precipitation (volume-weighted concentration) measurements in milligramsPerLiter units
and were aggregated to a monthly timescale.

生态趋势（EcoTrends）项目于2004年由黛布拉·彼得斯博士（乔纳达盆地长期生态研究（Long-Term Ecological Research, LTER）站，美国农业部农业研究服务局（USDA-ARS）乔纳达实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究（Long-Term Ecological Research, LTER）站，美国农业部林务局（USDA-FS）卢奎洛实验林）创立，旨在支持长期生态数据集的采集与分析工作。本项目属于大型综合研究工作，核心目标在于提升长期数据的可获取性与实际使用率。目前，共有约50个由州级与联邦政府资助的研究站点参与生态趋势项目并贡献数据，其中涵盖全部26个长期生态研究（LTER）站点，以及由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（United States Geological Survey, USGS）及众多高校资助的站点。生态趋势项目的数据集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Web应用，为用户提供持续的数据汇编与数据获取服务。作为LTER溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，正在进行中的数据汇编工作通过手动与自动两种处理方式持续更新。该网络门户是乔纳达LTER站与LTER网络办公室的合作成果。本项来自冰川湖泊生态系统实验站点（Glacier Lakes Ecosystems Experiments Site, GLA）的数据集，包含以毫克每升（mg/L）为单位的降水氯化物（体积加权浓度）测量值，且已按月度时间尺度进行聚合。
