Weatheo Data Desk
Weather data analysis
The Weatheo Data Desk turns observation archives into reporting: how a season compared with the long-run normal, how a heatwave or a cold spell moved across a continent, and which cities ran furthest from their usual climate.
Every report publishes its method, its period and a CSV of the figures it quotes, so a number can be checked, reused and cited. Corrections are made in place and dated.
