A precise definition

Live does not mean instantaneous.

Climate measurements are checked, calibrated and sometimes revised. Here, “live” means the latest defensible observation is maintained as its scientific source publishes it—and its age is never hidden.

Read the methodology
Measured
Direct observations from instruments, usually aggregated and quality-controlled.
Estimate
A scientific analysis that combines observations, corrections or spatial modelling.
Forecast
A value about the future. This site does not present forecasts as current measurements.
Freshness
The source update date is shown separately from the observation period.
