Flake and Weisberg PJ mortality raw data

Data used for Flake and Weisberg (accepted) Fine-scale stand structure mediates drought-induced tree mortality in pinyon-juniper woodlands. <br>ALL_climate_variables.csv is climate variables extracted from PRISM or other climate rasters, extracted for each plot.all_vars_EXPORT.csv provides some stand structure and topographic variables for each plot.map_mat_normals.csv gives normal mean annual precipitation and mean annual temperature for each plot, extracted from PRISM 4K rasters downscaled by a 10-m DEMall_trees_with_delta_and_ENN_041916.csv gives individual tree variables including the main response variable (Delta_pdc) and several neighborhood statistics.fdsi_annual_timeseries.csv gives values for FDSI (Williams et al., 2013) for each plot for all years between 1896-2014. ppt_winter_normals.csv gives winter precipitation normals for each plot, extracted from PRISM monthly rasters.soils_missing_imputed_012016.csv gives field-sampled soil texture measurements, with missing values imputed from nearby plots or replaced with SSURGO data, as described in the manuscript.<br>

本数据集为Flake与Weisberg已录用论文《精细尺度林分结构介导松-杜松林地干旱诱导树木死亡》的配套研究数据。
`ALL_climate_variables.csv` 为从PRISM或其他气候栅格中提取的各样地气候变量；
`all_vars_EXPORT.csv` 提供了各样地的部分林分结构与地形变量；
`map_mat_normals.csv` 给出了各样地的多年平均年降水量与年平均气温，数据源自经10米数字高程模型（DEM）降尺度的PRISM 4K栅格；
`all_trees_with_delta_and_ENN_041916.csv` 包含单棵树木的各项属性变量，涵盖核心响应变量（Delta_pdc）与多项邻域统计指标；
`fdsi_annual_timeseries.csv` 提供了1896年至2014年间所有年份各样地的森林干旱严重度指数（FDSI，Williams等，2013）数值；
`ppt_winter_normals.csv` 给出了各样地的冬季降水多年平均值，数据提取自PRISM月度栅格；
`soils_missing_imputed_012016.csv` 包含野外采样获取的土壤质地测量数据，其中缺失值已通过邻近样地数据插补或替换为SSURGO数据集数据，具体处理方法详见论文。
