## Method

Use the compatible published metric temp_mean_annual_c, g11_mean_annual_temp_c, temp_annual_c, climate_avg_temp_annual_c, climate_avg_temp_c, g11_temperature_avg_c, g13_temperature_avg_c, g13_climate_temperature_annual_c, keep one machine-readable unit family with direct source URLs, and sort descending.

## Boundary

This ranking is a source-backed reference. Read the source, geographic grain and observation date before comparing rows.
