context
Before you play
Robert FitzRoy published his first public forecast in The Times using weather reports. The U.S. Signal Office began publishing maps with observations from different cities. Later, the World Meteorological Organization formalised international cooperation; TIROS-1 supplied cloud images from space, and ECMWF began producing operational medium-range forecasts.
significance
Why this collection matters
These five rounds separate distinct steps: communicating a forecast, gathering observations on maps, coordinating data across countries, observing clouds from space and producing operational forecasts several days ahead.

questions
Before you start
1Was WMO established in the same year it became a UN agency?
No. The WMO Convention entered into force and the organization was established in one year; its designation as a UN specialized agency came the following year.
2Why was TIROS-1 launched?
The mission tested whether satellite cameras could provide cloud images useful for observing weather from space.
