H. J. Andrews Experimental Forest site, station Reference Stand 2, study of soil temperature at 10 cm depth (mean minimum) in units of celsius 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 H. J. Andrews Experimental Forest (AND)
contains soil temperature at 10 cm depth (mean minimum) measurements in celsius units
and were aggregated to a monthly timescale.

EcoTrends项目由Debra Peters博士（乔纳达盆地长期生态研究站，USDA-ARS乔纳达实验牧场）与Ariel Lugo博士（卢奎洛长期生态研究站，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采集与分析工作。该项目是一项大型综合研究计划，聚焦于提升长期生态数据的可访问性与应用价值。目前，已有约50个州立及联邦资助的研究站点参与并为EcoTrends项目贡献数据，其中包含全部26个长期生态研究（Long-Term Ecological Research, LTER）站点，以及美国农业部农业研究服务局（ARS）、美国农业部林务局、美国能源部、美国地质调查局（USGS）资助的站点与众多高校。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Web应用程序，为用户提供持续的数据汇编与访问服务。作为LTER溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，持续开展的数据汇编工作通过人工与自动两种处理方式进行更新。该网络门户由乔纳达LTER站与LTER网络办公室合作开发。以下来自H.J.安德鲁斯实验森林（AND）的数据集，包含以摄氏度为单位的10厘米深度土壤温度（平均最低值）测量数据，且已按月度时间尺度完成聚合。
