Frequently asked questions
- What is Windnavigator, and how does it support wind energy development?
Windnavigator is a wind resource data platform that provides high-resolution wind maps, historical climate datasets, and GIS-ready wind data for site selection and feasibility studies. It enables wind developers to assess wind energy potential with accuracy and confidence before making investment decisions.
- What is mesoscale modeling, and why is it important for wind assessments?
Mesoscale modeling simulates atmospheric conditions at a regional scale (1-100 km resolution). It captures wind behavior over large areas and accounts for synoptic weather patterns, making it essential for long-term wind resource assessments and climate modeling.
- What is microscale modeling, and how does it refine wind predictions?
Microscale modeling focuses on localized wind flow (less than 1 km resolution), capturing fine-scale effects such as terrain roughness, vegetation and buildings. It improves wind speed accuracy at specific turbine locations, reducing uncertainty in energy yield estimates.
- What is a Wind Resource Grid (WRG), and how is it used?
A WRG is a dataset that provides wind speed, Weibull parameters and power density at various hub heights. Developers use WRGs for early-stage site assessments, met tower siting and wind farm design validation.
- How does ULTRUS Windnavigator improve wind prospecting?
Windnavigator delivers 200 m-resolution wind maps, long-term reanalysis datasets (MERRA-2, ERA5, WRF), and GIS-compatible export formats for easy integration into wind modeling software.
- What is the Weibull distribution, and why is it important?
The Weibull distribution is a statistical model that describes wind speed variability at a given location. The two parameters, Weibull A (scale) and Weibull k (shape), help predict energy production potential and turbine efficiency.
- Can I export wind resource data for use in GIS and wind modeling software?
Yes, Windnavigator supports export formats such as GeoTIFF, shapefile (.shp), Google Earth (KMZ), CSV and JSON, making it easy to use in GIS platforms and energy modeling software.
