Plum Island Ecosystems site, station NWS COOP #193505, Haverhill, MA, study of air temperature (mean maximum ) in units of celsius 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 Plum Island Ecosystems (PIE) contains air temperature (mean maximum ) measurements in celsius units and were aggregated to a yearly timescale.EcoTrends项目于2004年由黛布拉·彼得斯博士（约纳达盆地长期生态研究（Long-Term Ecological Research, LTER）站点，美国农业部农业研究服务局约纳达实验牧场）与阿里尔·卢戈博士（卢奎约长期生态研究站点，美国农业部林业局卢奎约实验林）创立，旨在支持长期生态数据集的采集与分析。该项目为大型综合研究工作，核心目标是提升长期生态数据的可获取性与利用效率。目前，已有约50个由州级及联邦政府资助的研究站点参与并为EcoTrends项目贡献数据，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（ARS）、美国农业部林业局、美国能源部、美国地质调查局（USGS）与众多高校资助的站点。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Web应用，支持用户持续开展数据整合与数据获取工作。作为LTER溯源感知综合跟踪架构（PASTA）的组成部分，正在进行的数据整合工作通过人工与自动两种处理方式完成更新。该网络门户由约纳达LTER站点与LTER网络办公室合作开发。以下来自普拉姆岛生态系统（PIE）的数据集包含以摄氏度为单位的气温（平均最高温）测量数据，且已按年时间尺度完成聚合。
