Niwot Ridge site, station NWS COOP #050848, Boulder, CO, study of air temperature (mean) in units of celsius 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 Niwot Ridge (NWT)
contains air temperature (mean) measurements in celsius units
and were aggregated to a yearly timescale.

EcoTrends项目由黛布拉·彼得斯博士（隶属于美国农业部-农业研究局乔纳达实验牧场的乔纳达盆地长期生态研究（Long-Term Ecological Research，LTER）站点）与阿里尔·卢戈博士（隶属于美国农业部林业局卢奎洛实验林的卢奎洛长期生态研究（Long-Term Ecological Research，LTER）站点）于2004年发起，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生态数据的可获取性与应用效能。目前，已有约50个州级与联邦级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，LTER）站点，以及由美国农业部农业研究局（ARS）、美国农业部林业局、美国能源部、美国地质调查局（USGS）及多所高校资助的站点。EcoTrends项目的数据可通过探索性网络门户（http://www.ecotrends.info）获取。该网络门户依托交互式网络应用程序，助力用户持续推进数据整合与开放共享。长期生态数据整合工作通过长期生态研究溯源感知综合跟踪架构（LTER Provenance Aware Synthesis Tracking Architecture，PASTA）中的手动与自动处理流程进行更新。本网络门户由乔纳达LTER与LTER网络办公室联合打造。本次提供的尼沃特岭（NWT）数据集包含以摄氏度为单位的年均气温测量数据，并已聚合至年度时间尺度。
