California Current Ecosystem site, station Lindbergh Field Airport, San Diego, CA, 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 California Current Ecosystem (CCE) 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（霍纳达盆地长期生态研究站点（Long-Term Ecological Research, LTER），美国农业部农业研究局（USDA-ARS）霍纳达实验牧场）与阿里尔·卢戈博士（卢基略长期生态研究站点（LTER），美国农业部林务局（USDA-FS）卢基略实验林）创立，旨在支持长期生态数据集的收集与分析。该项目是一项大型综合研究工作，致力于提升长期数据的可及性与利用效率。目前，共有约50个州级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（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。EcoTrends项目的数据集可通过探索型网络门户（http://www.ecotrends.info）获取，该门户借助交互式网络应用程序，支持用户持续开展数据汇编与数据获取工作。作为长期生态研究（LTER）溯源感知综合跟踪架构（PASTA）的组成部分，项目的日常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。该网络门户由霍纳达LTER站点与LTER网络办公室合作打造。下述来自加州洋流生态系统（California Current Ecosystem, CCE）的数据集包含以摄氏度为单位的气温（平均最高值）实测数据，且已被聚合为年度时间尺度。
