LCZO -- Precipitation, GIS/Map Data -- Luquillo Mountains, Puerto Rico -- (2014-2014)

These geospatial data sets were developed as part of a new analysis of all known current and historical rain gages in the Luquillo Mountains, Puerto Rico published in the journal article Murphy, S.F., Stallard, R.F., Scholl, M.A., Gonzalez, G., and Torres-Sanchez, A.J., 2017, Reassessing rainfall in the Luquillo Mountains, Puerto Rico: Local and global ecohydrological implications: PLOS One 12(7): e0180987, p. 1-26, https://doi.org/10.1371/journal.pone.0180987. That article provides a revised map of mean annual precipitation developed using elevation regression functions and residual interpolation, and that map is presented here in a raster file. Most previous forest- and watershed-wide estimates of precipitation (and evapotranspiration, as inferred by a water balance) have assumed that precipitation increases consistently with elevation in the Luquillo Mountains; therefore, precipitation in leeward Luquillo watersheds has been overestimated by up to 40%.Because the Luquillo Mountains often serve as a wet tropical archetype in global assessments of basic ecohydrological processes, these revised estimates are relevant to regional and global assessments of runoff efficiency, hydrologic effects of reforestation, geomorphic processes, and climate change.

本地理空间数据集作为对波多黎各洛昆伊洛山脉所有已知当前及历史降雨量计的新分析的一部分而开发，该分析发表在Murphy, S.F.，Stallard, R.F.，Scholl, M.A.，Gonzalez, G. 和 Torres-Sanchez, A.J. 于2017年发表的学术论文中：重新评估波多黎各洛昆伊洛山脉的降雨：局部与全球生态水文学的影响：《PLOS One》第12卷第7期：e0180987，第1-26页，https://doi.org/10.1371/journal.pone.0180987。该文章提供了一幅基于海拔回归函数和残差插值开发的年均降水量修正图，该图以栅格文件形式在此呈现。大多数之前对森林和流域范围的降水量（以及通过水文学平衡推断的蒸散量）的估计都假设降水量与海拔高度呈一致性增加；因此，洛昆伊洛山脉背风面的流域降水量被高估了高达40%。由于洛昆伊洛山脉常被作为全球对基本生态水文学过程评估的湿润热带典型代表，这些修正后的估计对区域和全球对径流效率、森林恢复的水文学效应、地貌过程以及气候变化的影响评估具有重要意义。
