Priest River Experimental Forest site, station NWS COOP #107386, Priest River Experimental Station, ID, study of air temperature (mean minimum) 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 Priest River Experimental Forest (PRI) contains air temperature (mean minimum) measurements in celsius units and were aggregated to a yearly 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（Long-Term Ecological Research）、美国农业部农业研究局（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（Long-Term Ecological Research）、美国农业部林业局（USDA-FS）卢奎洛实验林）于2004年创立，旨在支持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计划，核心目标为提升长期生态数据的可获取性与利用率。目前，已有约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，其中涵盖全部26个LTER站点，以及由美国农业部农业研究局（ARS）、美国农业部林业局、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。EcoTrends项目的数据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应用程序，支持用户持续开展数据汇编与数据获取工作。作为LTER溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，持续进行的数据汇编工作通过人工与自动处理相结合的方式完成更新。该网络门户是约尔纳达LTER与LTER网络办公室的合作成果。本次提供的普里斯特河实验林（Priest River Experimental Forest, PRI）数据集包含以摄氏度为单位的空气平均最低温测量数据，且已被聚合至年度时间尺度。
