README

This repository contains data required to repeat the analyses described in the manuscript "Extreme weather magnifies the effects of forest structure on wildfire, driving increased severity in industrial forests." The code used to run these analyses and process the data are published separately, both on Github and in a static Zenodo repository, because the size of the data exceeded Github's file size limits.

Download instructions

The data in this repository were split from an initial .zip file into four subfiles, each less than or equal to 2.1 Gb to facilitate upload. To access the data, the user will have to first download these partial files, and then merge them on their local machine. Here we provide brief instructions for doing so on a Unix-based computer. 

1. Download partial files 

First, download the four subfiles from this repository:

• data_part_aa
• data_part_ab
• data_part_ac
• data_part_ad

3. Merge files on local machine

Next, merge the four subfiles into a single .zip file, and finally unzip the data into the same directory as the code downloaded from Github or Zenodo. This way, the code will correctly reference the files in the dataset. 

Here is a bash script to complete this full workflow, downloading, merging, and unzipping the data archive. 

#!/bin/bash

# Download and reassemble split archive from Zenodo
for part in aa ab ac ad; do
  wget -c https://zenodo.org/record/15848846/files/data_part_$part
done
cat data_part_aa data_part_ab data_part_ac data_part_ad > data.zip

# verify checksum
# should match 944cc633e20fa460ab0131a93c953573
md5sum data.zip

# Unzip into the main directory, so that the scripts will function as intended. 
unzip data.zip -d severity_and_silviculture/data
