Stations

Every station, what it measures and where it sits.

What a station measures

Element	Instrument	Why it matters
Rainfall	Tipping bucket rain gauge	Flood and drought assessment; the core climate record
Temperature	Shielded thermometer or probe	Heat guidance, aviation, climate trend
Wind	Anemometer and vane	Marine and aviation forecasts, warning thresholds
Pressure	Barometer	Tracking systems and confirming model analysis
Humidity	Hygrometer	Shower potential, heat stress, aviation

Siting matters as much as the instrument

A station's readings are only comparable with others if it is sited to World Meteorological Organization standards — clear of buildings and trees, at standard instrument height, with proper shielding from direct sun.

A well-sited cheap sensor beats a badly-sited expensive one. Most bad weather data is a siting problem, not an instrument problem.
