§01 — What's inside

The Global Historical Climatology Network daily record: temperature, precipitation, snow, and wind from over 100,000 land stations, some reaching back to the 1830s. Quality flags preserved, station metadata joined, and gap-filled variants supplied as a separate split so you can choose raw or modelled.
