SARWind Solutions:
Tailored Insights for Every Development Phase
SARWind ATLAS & ATLAS+
SARWind ATLAS and ATLAS+ provide high-resolution, long-term wind statistics derived from satellite observations, helping developers make informed site selection decisions.
Spatial planning and risk assessment in early-stage development, ensuring a reliable and data-driven approach to offshore wind farm siting.
- SARWind ATLAS delivers wind data at 10 meters above sea level, offering precise insights into surface wind conditions.
- SARWind ATLAS+ extends this analysis up to 300 meters in altitude, enabling a detailed vertical wind profile critical for turbine height optimization.
Both products support spatial planning and risk mitigation, helping offshore wind developers reduce uncertainties before committing to costly on-site measurements.
SARWind TIMESERIES
SARWind TIMESERIES offers long-term, high-frequency wind data, essential for offshore wind resource assessment studies. With wind speed, direction, and vertical shear recorded at one-hour intervals, this dataset provides reliable input for energy yield modeling and financing decisions.
Available at 10m above sea level and in altitude, SARWind TIMESERIES enhances bankability by ensuring developers have continuous, validated wind data at specific locations within lease areas.
It provides reliable wind data for informed investment and energy yield projections.

The Science Behind SARWind:
How It Works
Cutting-Edge Satellite Observations
SARWind leverages Synthetic Aperture Radar (SAR) imagery from European satellites to directly observe air-sea interactions affecting offshore wind conditions:
- Wind-related effects: convective cells, atmospheric fronts, turbine wake effects.
- Non-wind factors: rain cells, ocean currents, sea surface films (biological, pollution).
Processed by Remote Sensing Experts
Since 2003, CLS has been developing a high-level expertise to retrieve geophysical information at sea surface level from SAR imagery, including wind, wave, and current products.

Advanced Data Processing & Validation
Our methodology is backed by 20 years of remote sensing expertise and validated against:
- 10m altitude data: 63 surface anemometers, 11,050 in-situ observations (US case study).
- Up to 300m altitude: 28 LiDARs and met masts, showing 1.9% absolute bias error (vs. 3.7% for high-resolution mesoscale models).
