Canadian weather radar visibility maps

Executive summary

Environment and Climate Change Canada (ECCC) manages a network of radars across Canada that gives us important weather services. Our radars help meteorologists predict daily weather and track severe weather events such as thunderstorms, hurricanes, floods, and tornadoes.

However, wind turbines near the radars disturb the important weather information we normally get from them. Since the wind energy sector has grown so quickly, we are asking wind farm developers to contact us early in their plans.

Our goal is to support the progress of renewable energy and at the same time to deliver quality weather services. Below you will find a series of maps that show where wind turbines would likely be seen by the weather radars and thus possibly cause interference. Wind farm developers may use these maps to help find locations where wind turbines are less likely to disturb weather radar data.

Canadian weather radar visibility maps

ECCC should be consulted through radarsmeteo-weatherradars@ec.gc.ca on all wind farm proposals in Canada as early as possible in the project planning phase. ECCC will conduct a preliminary radar impact assessment of the project and will confirm if mitigation measures will be required.

The map below shows the locations in Canada where wind turbines could be visible to ECCC’s 32 operational weather radars. Turbines that are visible to our radars could potentially cause radar interference and therefore impact ECCC’s ability to provide quality weather forecasts and warnings to Canadians. The information shown in the following maps may assist industry in identifying potentially suitable locations for siting turbines. The data shown on the maps will be made available for download in GeoJSON format in the near future. This webpage will be updated with a hyperlink to download once the data is published.

It is important to note that the radar visibility layers shown in the maps were generated using a simple viewshed tool and does not indicate the degree of visibility to the radars. Therefore, the results may not be completely accurate due to limitations in the data and/or tool. There could be cases where turbines may or may not be visible to ECCC’s radars despite being outside or within these visibility layers. Wind farm developers should contact ECCC regardless of where in Canada their project is taking place. For any questions or feedback regarding the maps, please contact us at radarsmeteo-weatherradars@ec.gc.ca.

How to interpret the maps

The radar site locations are marked with a black dot. The hatch-filled red circles around each radar represent a 10 kilometre (km) radius “definite impact zone”, where significant impacts to the radar are more likely to occur and therefore turbines should not be built within this zone. The dashed circles around each radar represent a 10-60 km radius “moderate impact zone”, where moderate-to-significant impacts to the radar are more likely to occur if turbines are built within this zone.

The colour display surrounding the radars represents the locations where wind turbines could be visible to the radars. The radar visibility maps have been created for turbine models with total heights (i.e. tower base to blade tip) of 150, 200 and 250 metres above ground level (mAGL). If any part of a turbine is visible to a weather radar, some radar interference is expected.

Any region not covered by the colour display indicates that a wind turbine with a total height less than or equal 250 mAGL should likely not be visible to the radars. However, a turbine with a total height greater than 250 mAGL may be visible to a radar in those areas and therefore further analysis is required.

Light orange areas indicate locations where 200 m tall turbines are likely to be visible to the radars. Yellow areas indicate locations where 250 m tall turbines are likely to be visible to the radars. Turbine heights are measured from tower base to blade tip and expressed in metres above ground level. Hatch-filled red circles around each radar represent a 10 kilometre (km) radius “definite impact zone”, where significant impacts to the radar are more likely to occur and therefore turbines should not be built within this zone. Dashed circles around each radar represent a 10-60 km radius “moderate impact zone”, where moderate-to-significant impacts to the radar are more likely to occur if turbines are built within this zone.
Holyrood radar visibility map

Newfoundland

Long description

Map is centered on the radar station near Holyrood, Newfoundland and Labrador. Legend: The black dot indicates where the weather radar is located. Dark orange areas indicate locations where 150 metre (m) tall turbines are likely to be visible to the radars. Light orange areas indicate locations where 200 m tall turbines are likely to be visible to the radars. Yellow areas indicate locations where 250 m tall turbines are likely to be visible to the radars. Turbine heights are measured from tower base to blade tip and expressed in metres above ground level. Hatch-filled red circles around each radar represent a 10 kilometre (km) radius “definite impact zone”, where significant impacts to the radar are more likely to occur and therefore turbines should not be built within this zone. Dashed circles around each radar represent a 10-60 km radius “moderate impact zone”, where moderate-to-significant impacts to the radar are more likely to occur if turbines are built within this zone.
