Moorea Coral Reef site, station MeteoFrance Afareaitu #2, study of precipitation in units of centimeter 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 Moorea Coral Reef (MCR)
contains precipitation measurements in centimeter 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站（Long-Term Ecological Research, LTER），美国农业部农业研究服务局（USDA-ARS）约尔纳达实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究站（Long-Term Ecological Research, LTER），美国农业部林务局（USDA-FS）卢奎洛实验森林）创立，旨在支撑长期生态数据集的采集与分析工作。
本项目属于大型综合研究工作，核心目标在于提升长期生态数据的可获取性与实际应用价值。
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（Agricultural Research Service, ARS）、美国农业部林务局、美国能源部、美国地质调查局（USGS）及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。
该网络门户依托交互式Web应用程序，可为用户提供持续的数据汇编与数据获取服务。
作为长期生态研究站溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，常态化的数据汇编工作通过人工与自动两种处理方式完成更新。
该网络门户由约尔纳达LTER与LTER网络办公室联合开发运营。
下述来自莫雷阿珊瑚礁（Moorea Coral Reef, MCR）的数据集包含以厘米为单位的降水观测数据，且已按年时间尺度进行聚合。
