Florida Coastal Everglades site, station NADP Station FL11, Everglades National Park-Research Center, FL, study of pH of precipitation in units of dimensionless 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 pH of precipitation measurements in dimensionless units and were aggregated to a monthly timescale.

生态趋势（EcoTrends）项目由黛布拉·彼得斯博士（乔纳达盆地长期生态研究站，美国农业部农业研究局乔纳达实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究站，美国农业部林务局卢奎洛实验林）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计划，聚焦于提升长期生态数据的可获取性与应用价值。目前共有约50个由州政府及联邦政府资助的研究站点参与并为生态趋势项目贡献数据，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）及众多高校资助的研究站点。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，该门户依托交互式网页应用，支持用户持续开展数据整合与数据获取操作。作为长期生态研究网络溯源感知综合跟踪架构（PASTA）的组成部分，正在推进中的数据整合工作通过人工与自动双重处理流程实现更新。该网络门户由乔纳达LTER站与LTER网络办公室合作共建。本次来自佛罗里达海岸大沼泽地（Florida Coastal Everglades, FCE）的数据集包含以无量纲单位记录的降水pH测量值，且数据已被聚合至月度时间尺度。
