Every day's rainfall on Earth, 1981–2025, in one free map
New Zealand startup see1m just put 45 years of global daily rainfall behind a free interactive atlas. The World Rain Player is the firm's first public demo of its persistent data framework: instead of flattening 5 km cells into a single statistic, it preserves every day from 1981 to 2025. That means you can watch seasons move, compare years, and read each cell against its own long-term mean.
