cup anemometer

[′kəp an·ə′mäm·əd·ər]

The Galion also exhibited higher wind speeds than the mast-mounted cup anemometers likely due to the spatial sampling, which meant it was not as strongly impacted by the presence of wind turbines upstream (see the section below that discusses a wake study).
Wind data collected conventionally using cup anemometers mounted on a wind mast is susceptible to distortion from the sensors and the mast itself, which is typically around 80m high.
