Changelog

What changed on the atlas and in the data, newest first — including the mistakes. Data corrections also flow to the open dataset and its mirrors.

18 July 2026

Dataset edition 2026.08 published to every mirror: GitHub release, a new Zenodo DOI version, Hugging Face and Kaggle.
A pass over the site copy for tone, and crisper favicons (96/192 px).
This page, and an about page — overdue.

The climate layer is now NASA POWER end to end (2001–2020). Earlier builds anchored temperatures to CRU CL v2.0, a 1961–1990 normal — mixing two reference periods was wrong, so CRU is gone entirely.
Fixed: the continent column. It used to come from per-airport metadata, was missing for a quarter of destinations, and silently defaulted to Asia — Fiji, Greenland and the Bahamas were all filed under "Asia". It's now derived from geography, with explicit rules for the six transcontinental countries.
Replaced rainy-days-per-year with annual rainfall in mm: POWER measures precipitation depth, not wet-day counts, and the old column wasn't worth guessing.

Destination pages gained computed "How sunny is X?" verdicts — every claim traceable to the data.
Globe dots moved from the airport onto the city they serve.
Homepage payload halved (1.43 MB → 0.71 MB on the wire).
