Coweeta site, station Wilkes County, NC (FIPS 37193), 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 Coweeta (CWT)
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站，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站，美国农业部-林务局（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采集与分析。本项目为一项大型综合研究工作，聚焦于提升长期数据的可获取性与应用价值。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，其中包括全部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服务局（Agricultural Research Service, ARS）、美国农业部林务局、美国能源部、美国地质调查局（United States Geological Survey, USGS）资助的站点，另有众多高等院校参与。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，支持用户持续开展数据汇编与数据获取工作。作为溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的一部分，持续进行的数据汇编工作通过手动与自动两种处理方式完成更新。该网络门户由乔纳达LTER站与LTER网络办公室合作开发。本数据集取自考伊塔（CWT）站点，包含制造业就业人口占总就业人口百分比的测量数据，单位为百分比，并已聚合至年度时间尺度。
