Fraser Experimental Forest site, station Headquarters 3, 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 Fraser Experimental Forest (FRA)
contains air temperature (mean maximum ) measurements in celsius units
and were aggregated to a yearly timescale.

EcoTrends项目由黛布拉·彼得斯博士（Jornada盆地长期生态研究网（Long-Term Ecological Research, LTER），美国农业部农业研究局（USDA-ARS）Jornada试验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究网（Long-Term Ecological Research, LTER），美国农业部林务局（USDA-FS）卢奎洛试验林）于2004年创立，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项目，致力于提升长期生态数据的可获取性与利用效能。目前，约有50个州政府及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（USDA-ARS）、美国农业部林务局（USDA-FS）、美国能源部、美国地质调查局（US Geological Survey, 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。该网络门户依托交互式网页应用，支持用户持续开展数据汇编与数据获取工作。作为长期生态研究网溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，持续推进的数据汇编工作通过手动与自动两种处理方式完成更新。本网络门户由Jornada LTER与LTER网络办公室合作开发。下述来自弗雷泽试验林（FRA）的数据集包含以摄氏度为单位的空气温度（日最高温均值）测量值，且已被聚合至年际时间尺度。
