Data and Code for “Subsurface Storage Capacity Controls on Tree Ring Sensitivity to Precipitation"

This supplement includes a Python notebook and an R file that reproduce the figures and analyze the tree-ring and climate data used in the manuscript.

In order to execute the code, users should have an Earth Engine account and obtain the raw CRN files from the NOAA National Centers for Environmental Information repository (https://www.ncei.noaa.gov/pub/data/paleo/treering/chronologies), available as a compressed archive file (itrdb-v713-usa-crn.zip).

本补充材料包含一份Python交互式笔记本与一份R脚本文件，可复现论文手稿中的全部图表，并对研究所用的树木年轮与气候数据开展分析。
若需运行本代码，用户需拥有谷歌地球引擎（Earth Engine）账号，并需从美国国家海洋和大气管理局（NOAA）国家环境信息中心的资源库中获取原始CRN文件；该文件以压缩归档包itrdb-v713-usa-crn.zip的形式提供，资源库链接为：https://www.ncei.noaa.gov/pub/data/paleo/treering/chronologies。
