Konza Prairie site, station Riley County, KS (FIPS 20161), study of farmland acres (total) in units of acre 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 Konza Prairie (KNZ)
contains farmland acres (total) measurements in acre units
and were aggregated to a yearly timescale.

EcoTrends项目于2004年由德布拉·彼得斯博士（约尔纳达盆地长期生态研究（Long-Term Ecological Research，简称LTER）站点，美国农业部农业研究服务局（USDA-ARS）约尔纳达试验牧场）与阿里尔·卢戈博士（卢奎洛LTER站点，美国农业部林务局（USDA-FS）卢奎洛试验林）创立，旨在支撑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计划，核心目标是提升长期数据的可获取性与利用率。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，其中涵盖全部26个LTER站点，以及由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）和众多高校资助的站点。EcoTrends项目的数据集可通过探索性网络门户（http://www.ecotrends.info）获取，该门户依托交互式网页应用，支持用户持续开展数据汇编与数据获取工作。依托LTER溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture，简称PASTA），项目通过手动与自动结合的处理流程，持续更新数据汇编工作。该网络门户由约尔纳达LTER站点与LTER网络办公室联合开发。本次来自康扎草原（Konza Prairie，简称KNZ）的数据集以英亩为单位，包含农田总面积测量值，并已聚合至年度时间尺度。
