Harvard Forest site, station Rockland County, NY (FIPS 36087), study of population employed in manufacturing (percent of total) in units of percent 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 Harvard Forest (HFR)
contains population employed in manufacturing (percent of total) measurements in percent units
and were aggregated to a yearly timescale.

EcoTrends项目由黛布拉·彼得斯博士（乔纳达盆地长期生态研究网（Long-Term Ecological Research, LTER），美国农业部农业研究服务局（USDA-ARS）乔纳达实验牧场）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）卢奎洛实验森林）于2004年创立，旨在支持长期生态数据集的采集与分析工作。本项目为大型综合研究项目，核心目标在于提升长期生态数据的可获取性与利用效率。当前共有约50个州级与联邦资助的研究站点参与EcoTrends项目并贡献数据，其中涵盖全部26个长期生态研究网（LTER）站点，以及由美国农业部农业研究服务局（USDA-ARS）、美国农业部林务局（USDA-FS）、美国能源部（US Department of Energy）、美国地质调查局（US Geological Survey, USGS）与众多高校资助的各类站点。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应用程序，支持用户持续开展数据整合与访问操作。持续推进的数据整合工作将通过手动与自动两种处理方式进行更新，该流程隶属于长期生态研究网（LTER）溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）。本网络门户是乔纳达LTER与LTER网络办公室的合作成果。本次来自哈佛森林（Harvard Forest, HFR）的数据集包含制造业就业人口占总就业人口百分比的观测数据，数据单位为百分比，且已按年度时间尺度完成聚合。
