Dorian (August 2019)

Dorian by Sentinel-1A

In the case of Dorian, three images from European Sentinel satellites coincided perfectly with the hurricane trajectory, making it possible to estimate maximum ocean surface sustained wind speeds above 60 m/s on August 30th before Dorian reached the Bahamas. In addition, Canadian satellite RadarSat-2 imagery was made available on September 1st, with support from public funds* received in the framework of the VIGISAT project managed by “Groupement Bretagne Télédétection” (GIS BreTel – Brittany Remote Sensing). On September 1st, maximum ocean surface sustained wind speeds reached more than 80m/s as Dorian approached the Bahamas.

Sentinel-1A image acquired over Dorian on 30/08/19 at 22:46 UTC with SAR image and ocean sea surface wind speed map estimated from the SAR product. The algorithm used is described in Mouche et al., 2019.
