Bonanza Creek site, station NADP Station AK01, Poker Creek, study of sulfate in wet deposition in units of kilogramsPerHectare on a monthly 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 Bonanza Creek (BNZ)
contains sulfate in wet deposition measurements in kilogramsPerHectare units
and were aggregated to a monthly timescale.

EcoTrends项目由德布拉·彼得斯博士（约那达盆地长期生态研究站点，美国农业部农业研究局（USDA-ARS）约那达实验牧场）与阿里尔·卢戈博士（卢奎约长期生态研究站点，美国农业部林务局（USDA-FS）卢奎约实验林）于2004年创立，旨在支撑长期生态数据集的采集与分析工作。该项目是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，共有约50个由州政府及联邦政府资助的研究站点参与并向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，简称LTER）站点，以及由美国农业部农业研究局（USDA Agricultural Research Service，简称ARS）、美国农业部林务局、美国能源部、美国地质调查局（US Geological Survey，简称USGS）与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，该门户依托交互式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，简称PASTA）的组成部分，持续进行的数据汇编工作通过手动与自动处理相结合的方式完成更新。该网络门户由约那达LTER站点与LTER网络办公室合作开发。以下来自博南扎克里克（Bonanza Creek，简称BNZ）的数据集，包含以千克每公顷为单位的湿沉降硫酸盐实测数据，且已被聚合至月度时间尺度。
