Geospatial data for Luquillo Mountains, Puerto Rico: Mean annual precipitation, elevation, watershed outlines, and rain gage locations

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.本套地理空间数据集（geospatial data sets）是针对波多黎各卢基略山脉（Luquillo Mountains）所有已知现存及历史雨量计（rain gages）开展的全新分析成果的一部分，相关分析成果发表于以下期刊论文：Murphy, S.F.、Stallard, R.F.、Scholl, M.A.、Gonzalez, G.、Torres-Sanchez, A.J.，2017年，《重新评估波多黎各卢基略山脉的降水：局地与全球生态水文意义》，《公共科学图书馆·综合》（PLOS One）12(7): e0180987，第1-26页，https://doi.org/10.1371/journal.pone.0180987。该论文依托高程回归函数（elevation regression functions）与残差插值（residual interpolation）方法构建了修正后的年均降水量分布图，本数据集即以栅格文件（raster file）形式提供该分布图。此前绝大多数针对森林及流域尺度的降水（以及通过水量平衡（water balance）推算的蒸散发（evapotranspiration））估算均假设卢基略山脉的降水量随海拔持续递增，因此背风坡卢基略流域的降水量被高估幅度最高可达40%。由于卢基略山脉常作为全球基础生态水文过程（ecohydrological processes）评估中的热带湿润生态系统原型，本次修正后的估算结果可应用于区域及全球尺度的径流效率（runoff efficiency）、造林水文效应（hydrologic effects of reforestation）、地貌过程（geomorphic processes）及气候变化（climate change）相关评估。
