Time Series
Time series data sets from UL Solutions can help you better understand the wind resource and energy production
potential for your wind project site. Available through the Windnavigator platform, use the wind map to select a
location and order historical time series data or virtual met mast data to help you establish long-term wind
conditions with onsite measurements, or perform analysis when onsite data is not available.
Typical Year Virtual Met Mast
Typical Year Virtual Met Mast data set is used to estimate the wind resource and energy production potential of a site when onsite measurements are not available
This data set contains a sample of 365 days scaled to our 200-meter resolution mean wind maps. The data is produced by a mesoscale model for a sample of 365 days from 15 years.The winds are scaled to our 200-meter mean wind speed maps.

Historical time series data sets are used to perform measure-correlate-predict (MCP) for the purpose of establishing long-term wind conditions with a meteorological tower or remote-sensing system. Historical time series data span periods from 10 years to over 35 years, depending on the source.
Global reanalysis data
This data is available for download from public sources including MERRA-2, and ERA5, covering anywhere in the world and spanning 1979 to the present. Download sample. Download sample.Weather Research and Forecasting data
WRF data are produced on UL Solutions high-performance computing cluster using the Weather Research and Forecasting (WRF) model initialized by ERA5. Available anywhere in the world, the user can choose to download a period of 10 or 20 years. Download Sample WRF.Data specifications
