Short summary
This paper presents a quantitative analysis of the impact of a wind farm on measurements from a nearby Doppler weather radar, based on 6 years of operational radar data. We show that radar measurements from a large area at and downrange from the wind farm as well as up to 3 km above the wind turbines were impacted. We also show that, when weather echoes give rise to higher reflectivity values than those of the wind farm, the negative impact of the wind turbines is greatly reduced.
