Coastal waves monitoring supported by Sentinel 3
Assimilation of Sentinel-3A SAR
SWH (NRT Data)
• Very good but higher at large Hs
• Flagged certain issues and
reported back to the cal/val team
• When updated data set available,
they will assess their impact

Brussels, 29 June 2017
Updated wave data set will be availbles
from COPERNICUS:
• Sentinel 3 (altimetry) - June 2017
• Sentinel 1 (SAR) - December 2017
Coastal winds monitoring supported by Sentinel 1 SAR
• L2 OCN products (MED):
generated routinely over the
Catalan Sea
• At present, L2 OCN
products are not available
over the Adriatic and North
Sea
• CEASELESS will push
for such product
generation in the
pilot areas

Validation of Sentinel 1 SAR Coastal wind Speeds agains in-
situ observations
SAR wind retrievals give reliable wind
speed measurements as close as 1 km
to the shore

Conclusions
Brussels, 29 June 2017
• Synthetic Aperture Radar (SAR) is the only satellite borne sensor that has enough
resolution to resolve wind speeds closer than 10 km to shore but the Geophysical Model
Functions(GMF) used for Sentinel 1 SAR wind retrieval are not fully validated as yet.
• Sentinel 2 ocean colors products offers the advantage of high spatial resolution (20
m), making it possible to observe narrow bays and estuaries where shellfish farms are
usually located.
• Wave dates from Sentinel 1/3 will be availables soon. Very interesting for validation
and assimilations in coupling models in order to resolved the inner shelf dynamics
properly.
What is currently available at the
Sentinel 1/2/3 side for Copernicus
coastal zone monitoring?
