California Current Ecosystem site, station Los Angeles County, CA (FIPS 6037), 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 California Current Ecosystem (CCE) contains population employed in manufacturing (percent of total) measurements in percent units and were aggregated to a yearly timescale.

EcoTrends项目由Debra Peters博士（乔纳达盆地长期生态研究站，美国农业部农业研究局（USDA-ARS）乔纳达实验牧场）与Ariel Lugo博士（卢奎略长期生态研究站，美国农业部林务局（USDA-FS）卢奎略实验林）于2004年创立，旨在支持长期生态数据集的采集与分析工作。本项目为大型综合研究项目，聚焦于提升长期数据的可获取性与应用效能。目前共有约50个由州政府及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局（Agricultural Research Service, ARS）、美国农业部林务局（USDA Forest Service）、美国能源部、美国地质调查局（US Geological Survey, USGS）及众多高校资助的研究站点。EcoTrends项目的数据可通过探索性网络门户（http://www.ecotrends.info）获取，该门户依托交互式网络应用程序，支持用户持续开展数据整合与获取工作。作为长期生态研究可溯源综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，持续推进的数据整合工作通过人工与自动处理相结合的方式完成更新。该网络门户由乔纳达LTER站与LTER网络办公室合作开发。本次来自加利福尼亚洋流生态系统（California Current Ecosystem, CCE）的数据集，包含以百分比为单位的制造业就业人口占总就业人口比例的实测数据，且已聚合至年度时间尺度。
