  Generated error by 1% measurement error Impact on AEP
Anemometer Δ1% wind speed measurement error
(Up to Δ6% energy, if anemometers are used to calculate the wind profile.)
Δ3% energy
Wind vane No direct linear relation, but will lead to poor wind farm design.  
Air pressure sensor Δ1% air pressure measurement error Δ1% energy
Temperature sensor 1° measurement error 0.35% energy
Air humidity sensor (at 40°C) 1% measurement error 0.05% energy
