The original archives are preserved under raw/archives/. Each archive was also extracted under raw/extracted/<archive-stem>/ to preserve the original .xlsx, .txt, .csv, and temperature-folder contents in inspectable form. The CX2_4 temperature folder is present at raw/extracted/CX2_4/CX2_4/Temperature/.

Extracted raw file counts: 745 files total; 419 .xlsx, 219 .txt, and 107 .csv.

Provenance Files
