Wind Shear Exponent Values for Offshore Locations in Algeria

Algeria's offshore wind energy potential is assessed using a multi-source workflow. The dataset contains derived atmospheric parameters, including shear exponent values, for candidate offshore zones, using multi-year ERA5 reanalysis data from 2019-2021. It was created by Said Khoudiri and published on figshare under a CC-BY-4.0 license.

Use Cases

• Ranking potential offshore wind farm sites based on derived shear exponent and Weibull statistics.
• Estimating turbine-level performance metrics like Net Annual Energy Production (Net AEP) and capacity factor using rotor equivalent wind speed (REWS).
• Screening candidate zones using bathymetry constraints and coastal wave height data for turbine hub height selection.

Strengths

• Derived from multi-year ERA5 reanalysis data, suggesting a consistent source.
• Includes key atmospheric parameters like shear exponent, Weibull statistics, and air density for site assessment.
• Results identify a favorable zone with a reported mean net annual energy production of 10.397 GWh/yr and a net capacity factor of 39.56%.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 5.5 KB, indicating limited scope.
