First WAPOSAL project publication is now published! The study maps Mediterranean Sea wave‑energy resources using high‑resolution Sentinel‑3A/B and CryoSat‑2 satellite altimetry validated against wave buoy observations. It identifies key high‑energy zones and seasonal variability, showing greatest wave‑power potential between the Balearic Islands and Sardinia and along select coastal regions.

How to access the .zarr files for each region:
The URL to the .zarr files are available by clicking “copy URL”.
As an example, the dataset can be accessed and loaded in Python using the following code:
python
import xarray as xr
data_url =“https://s3.waw4-1.cloudferro.com/EarthCODE/OSCAssets/waposal/AZ-CS2.zarr”
ds = xr.open_zarr(data_url, decode_times=False)
This dataset requires Zarr version 2
Using GDAL command-line tools:
bash
gdalinfo
