The easy sites are behind you
Whiffle Atlas and Whiffle Wind resolve terrain, stability and wake behaviour explicitly, from long-term wind climate to site-level yield.
Flow models approximate, complex sites don't forgive that
Flow models approximate, complex sites don't forgive that
Most wind projects are shaped by terrain, roughness and atmospheric stability. In these conditions, modelling assumptions directly influence wind inputs, wake losses and yield outcomes. Whiffle Atlas and Whiffle Wind are designed to represent these effects explicitly, from early-stage screening through to yield assessment.Whiffle Atlas provides the long-term wind climate.Whiffle Wind resolves how that wind behaves at your site. Together, they provide consistent inputs for wind resource and yield assessment.
Technology trusted by industry leaders
Whiffle models the atmosphere from first principles
Whiffle Atlas
Site screening, regional wind characterisation, long-term context for yield assumptions
21 years of mesoscale wind time series at 2 km resolution. Near-zero mean wind speed bias across all terrain types. Preview site wind statistics (wind rose, Weibull distribution, vertical shear profile) instantly and for free. Download the full time series for sites that make your shortlist.
Whiffle Wind
Wind resource assessment, wake modelling, bankable yield
Atmospheric LES (Whiffle LES) at 100 m resolution (or less), driven by ERA5 and Whiffle’s own meso model. Turbines explicitly in the domain. Outputs WRGs, full hourly time series and per-turbine AEP, compatible with wind resource assessment tools like WindPRO and OpenWind.
