Slot: Wind Speed Measurement Height (Metres) (wind_speed_measurement_height_m)

For WBGT and UTCI inputs, the wind-speed measurement height in metres. The ISO 7243 standard is 2 m, but reanalysis products often supply 10 m -- the height affects the WBGT value.

Tier: recommended

Why this slot matters

ISO 7243 assumes wind measured at 2 m, but reanalysis products usually supply 10 m wind; wind is slower near the ground, so an uncorrected 10 m input systematically shifts the resulting WBGT.

In plain terms

Wind blows faster the higher above the ground you measure it, so a "wind speed" is only meaningful together with the height it was taken at — this field records that height.
