Florida Coastal Everglades site, station NADP Station FL11, Everglades National Park-Research Center, FL, study of sulfur from sulfate 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 Florida Coastal Everglades (FCE)
contains sulfur from sulfate in precipitation (volume-weighted concentration) measurements in milligramsPerLiter units
and were aggregated to a monthly timescale.

EcoTrends项目由Debra Peters博士（约纳盆地长期生态研究站（Jornada Basin LTER），美国农业部农业研究局（USDA-ARS）约纳实验牧场（Jornada Experimental Range））与Ariel Lugo博士（卢奎洛长期生态研究站（Luquillo LTER），美国农业部林务局（USDA-FS）卢奎洛实验林（Luquillo Experimental Forest））于2004年发起成立，旨在支撑长期生态数据集的采集与分析工作。
本项目为大型综合研究计划，核心目标是提升长期生态数据的可获取性与使用率。目前共有约50个由州政府及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（Long-Term Ecological Research, LTER）站点，以及由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）及众多高校资助的各类站点。
EcoTrends项目的数据集可通过探索性网络门户（http://www.ecotrends.info）获取，该门户依托交互式网络应用，支持用户持续开展数据整合与获取操作。作为LTER溯源感知综合跟踪架构（LTER Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，项目的常态化数据整合工作通过人工与自动两种处理方式完成更新。本网络门户由约纳LTER站点与LTER网络办公室合作开发。
本次披露的数据集来自佛罗里达海岸大沼泽地（Florida Coastal Everglades, FCE），包含以毫克每升（mg/L）为单位的降水中硫酸盐硫含量（体积加权浓度）实测数据，且已按月度时间尺度完成聚合。
