Woodland Restoration Plot Network: Climatic Drought Index Data, Western Sydney Parklands (Western Sydney Regional Park), Australia, 1887-2014

Abstract: The Woodland Restoration Plot Network Drought data package contains Hutchinson’s Drought Indices calculated for the Prospect Reservoir, a location in close proximity of the Woodland Restoration Plot Network plots.

The Hutchinson climatic drought indices were invented by Professor Michael Hutchinson at the Australian National University in 1992. Professor Hutchinson designed two indices to reflect the duration and the severity of agricultural droughts using precipitation data. Professor Hutchinson subsequently collaborated with Mr Ivan Hanigan at LTERN to extend the drought indices with new methods, and a computer program was written to compute the indices using a range of climatic data sources.

The Woodland Restoration Plot Network Drought data package was created from three different data sources:
1) the Bureau of Meteorology Station data 1887-2014,
2) the Australian Water Availability Project’s gridded climate data 1900-2014 and
3) the TERN EMAST gridded climate data 1970-2012.

The project conducted a comparative analysis of the different climatic data sources, which differ in terms of their temporal extent and spatial resolution.

A synopsis of related data packages which have been collected as part of the Woodland Restoration Plot Network’s full program is provided at https://doi.org/10.25911/5c36e5688ff89

>Project funding: Financial support for development of the Drought Index R package was provided by Professor Tony McMichael's "Australia Fellowship" from the National Health and Medical Research Council, via the National Centre for Epidemiology and Population Health, Australian National University. LTERN funded the implementation of this method on the Woodland Restoration Plot Network site locations in 2015.

Between 2012 and 2018 this project was part of, and funded through the Long Term Ecological Research Network (LTERN) a facility within the Terrestrial Ecosystem Research Network (TERN) and supported by the Australian Government through the National Collaborative Research Infrastructure Strategy.

摘要：本林地恢复样地网络干旱数据包包含针对普罗斯佩克特水库（Prospect Reservoir）计算得到的哈钦森干旱指数，该水库紧邻林地恢复样地网络的样地分布区域。

哈钦森气候干旱指数由澳大利亚国立大学的迈克尔·哈钦森（Michael Hutchinson）教授于1992年提出。哈钦森教授依托降水数据设计了两项指数，用以表征农业干旱的持续时长与严重程度。后续，哈钦森教授与长期生态研究网络（Long Term Ecological Research Network, LTERN）的伊万·汉尼根（Ivan Hanigan）合作，通过新方法拓展了该干旱指数体系，并编写了计算机程序以基于多套气候数据源计算该指数。

本林地恢复样地网络干旱数据包整合自三类不同数据源：
1. 1887年—2014年澳大利亚气象局（Bureau of Meteorology）站点观测数据；
2. 1900年—2014年澳大利亚水资源可利用项目（Australian Water Availability Project）网格化气候数据；
3. 1970年—2012年陆地生态系统研究网络（Terrestrial Ecosystem Research Network, TERN）EMAST网格化气候数据。

本项目针对上述在时间跨度与空间分辨率上存在差异的多套气候数据源开展了对比分析。

>项目资助：干旱指数R包开发的资金支持，源自澳大利亚国立大学国家流行病学与人口健康中心依托国家健康与医学研究委员会提供的托尼·麦克迈克尔（Tony McMichael）教授“澳大利亚奖学金”。LTERN于2015年资助了本方法在林地恢复样地网络样地位置的落地实施。

2012年至2018年间，本项目隶属于TERN下属的LTERN，并由澳大利亚政府通过国家协同研究基础设施战略提供资助支持。
