Large files are hosted outside GitHub Pages via GitHub Releases. Local exercise files are browsable below.
Download as a single ZIP (Release asset).
Split archives, plus checksums and rebuild commands.
Clickable file listings for exe001–exe004.
These archives are split into parts. Download all parts, then reconstruct with cat, and verify with SHA-256.
cat ALL_FILE.tar.gz.part-* > ALL_FILE.tar.gz
sha256sum -c ALL_FILE.tar.gz.parts.sha256
cat global_emissions_v3_24aug2015.tar.gz.part-* > global_emissions_v3_24aug2015.tar.gz
sha256sum -c global_emissions_v3_24aug2015.tar.gz.parts.sha256
GitHub Pages does not list directories automatically, so these pages provide a browsable index for each exercise folder.
The wrfem_* files for Exercise 3 are provided as a zip:
sha256sum -c wrfem_exe003.zip.sha256
unzip wrfem_exe003.zip
Some Exercise 3 datasets were historically provided via FTP links. Many browsers do not open FTP links directly, so this site points you here instead.
If you still need the legacy FTP-only directories (Input_files, NEI11_processed, Run_emiss04, and emissions_data_2011), use an FTP client or a command-line FTP workflow, or re-host those files as GitHub Release assets like the 2015 data above.
