This year’s theme is Observing Today Protecting Tomorrow

From satellites orbiting Earth, to weather balloons released into the atmosphere, to ocean buoys and ships riding the waves, to remote stations, meteorological observations underpin everything from our daily routines to multi-billion dollar decisions.

The immense and often invisible observing and prediction system coordinated by the World Meteorological Organization is the backbone of our economies. It is the central nervous system for early warnings, which have saved many millions of lives.
