EOOffshore: Sentinel-1 Wind Data for the Irish Continental Shelf Region

O'Callaghan, Derek; McBreen, Sheila

EOOffshore is a Sustainable Energy Authority of Ireland (SEAI) funded project, which commenced in June 2020 in the School of Physics in University College Dublin (UCD). It presents a case study that demonstrates the utility of the Pangeo software ecosystem in the development of offshore wind speed and power density estimates, increasing wind measurement coverage of offshore renewable energy assessment areas in the Irish Continental Shelf (ICS) region. It has involved the creation of a new wind data catalog for this region, consisting of a collection of analysis-ready, cloud-optimized (ARCO) datasets featuring up to 21 years of available in situ, reanalysis, and satellite observation wind data products.

The European Union Copernicus Earth Observation (EO) programme and services are based on data collected from EO satellites, in particular, the Sentinel satellite missions. This includes the Sentinel-1 mission, which consists of C-band Synthetic Aperture Radar (SAR) imaging satellites in polar orbit. One of its main objectives is the provision of ocean monitoring services, where its Level-2 Ocean (OCN) products include an Ocean WInd field (OWI) component. This provides gridded estimates of wind speed and direction at 10 m above the surface, with a typical spatial resolution of 1 km. This particular catalog data set (eooffshore_ics_level3_sentinel1_ocn.zarr.tar.gz) contains 2015-2021 OCN wind products for the ICS region, which were retrieved from the Copernicus Open Access Hub (COAH) and the Alaska Satellite Facility (ASF). The data set was used in the EOOffshore project outputs presented (Scalable Offshore Wind Analysis With Pangeo) at the Meeting Exascale Computing Challenges with Compression and Pangeo 2022 EGU General Assembly session.
