Namoi groundwater drawdown grids

## **Abstract** \n\nThe dataset was derived by the Bioregional Assessment Programme from multiple source datasets. The source datasets are identified in the Lineage field in this metadata statement. The processes undertaken to produce this derived dataset are described in the History field in this metadata statement.\n\n\n\nThis dataset contains the grids of assessment units with the percentiles of drawdown for baseline, coal resource development pathway and additional coal resources development. Grids for every 5th percentile between the 5th and 95th percentile.\n\n## **Dataset History** \n\nThe results of drawdown from NAM_GW_Uncertainty_Analysis at the model nodes for baseline, crdp and acrd are interpolated to grids.\n\nThe custom made R script 'Rscripts/interpolateToGrid_i.R', which is executed on the high performance computers with the batch file interpolateNamoi.slurm. The script calculates the percentiles (every 5th between 5th and 95th) and interpolates them to the assessment units. The results are stored in ascii grid files Namoi_$maxtyp$_$scen$_quantile_$perc$.asc with $maxtyp$ tmax or dmax, $scen$ acrd, base and crdp and $perc$ the percentile.\n\n## **Dataset Citation** \n\nBioregional Assessment Programme (2017) Namoi groundwater drawdown grids.

**摘要**

本数据集由生物区域评估计划（Bioregional Assessment Programme）从多源数据集衍生而来。源数据集的相关信息已在本元数据声明的「谱系（Lineage）」字段中注明，而该衍生数据集的生成流程则详见本元数据声明的「历史（History）」字段。

本数据集包含评估单元栅格数据，涵盖基准情景、煤炭资源开发路径（CRDP）以及额外煤炭资源开发（ACRD）三种情景下的水位降深百分位数。栅格数据覆盖5至95分位数区间内每间隔5分位数的所有取值。

**数据集历史**

将NAM_GW_Uncertainty_Analysis得到的基准情景、CRDP与ACRD情景下模型节点处的水位降深结果插值为栅格数据。

所用定制开发的R脚本为`Rscripts/interpolateToGrid_i.R`，该脚本通过批处理文件`interpolateNamoi.slurm`在高性能计算机上运行。脚本可计算5至95分位数区间内每间隔5分位数的百分位数，并将其插值至评估单元。最终结果以ASCII栅格文件形式存储，文件命名格式为`Namoi_$maxtyp$_$scen$_quantile_$perc$.asc`，其中`$maxtyp$`取值为`tmax`或`dmax`，`$scen$`取值为`acrd`、`base`或`crdp`，`$perc$`为对应百分位数。
