Coweeta site, station Lumpkin County, GA (FIPS 13187), study of population employed in service (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 service (percent of total) measurements in percent units
and were aggregated to a yearly timescale.

EcoTrends项目于2004年由德布拉·彼得斯博士（约拿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）约拿实验牧场）与阿里尔·卢戈博士（卢奎约长期生态研究站点（Long-Term Ecological Research, LTER），美国农业部森林服务局（USDA-FS）卢奎约实验林）创立，旨在支持长期生态数据集的采集与分析工作。该项目为一项大型综合研究计划，致力于提升长期数据的可获取性与应用价值。目前，约有50个由州政府与联邦政府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服务局（USDA Agriculture Research Service, ARS）、美国农业部森林服务局、美国能源部、美国地质调查局（US Geological Survey, USGS）及众多高校资助的站点。EcoTrends项目的数据可通过探索性网络门户（http://www.ecotrends.info）获取。该网络门户通过交互式Web应用程序，支持用户持续开展数据汇编与数据获取工作。作为长期生态研究网溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，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。本网络门户由约拿LTER站点与LTER网络办公室合作开发。本次提供的科韦塔（Coweeta, CWT）数据集包含服务业从业人口占总从业人口百分比的测量数据，单位为百分比，且已聚合至年度时间尺度。
