Time Series Data

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

TY-VMM

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.

Key Features

365 days scaled to 200-meter resolution mean wind maps
Produced by mesoscale model sampling 15 years of data
Heights from 10-140m above ground

Historical Time Series

MCP Analysis Ready

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.

Available Sources

MERRA-2, ERA5, CFSR global reanalysis data
Weather Research and Forecasting (WRF) model data
Data spans 10 to 35+ years depending on source

Global Reanalysis Data

Available for download from public sources including MERRA-2 and ERA5, covering anywhere in the world and spanning 1979 to the present.

  • Global coverage with decades of historical data
  • Multiple height levels and meteorological parameters

WRF Model Data

Produced on UL Solutions high-performance computing cluster using the Weather Research and Forecasting (WRF) model initialized by ERA5.

  • High-resolution 3km or 9km grid spacing
  • Choose 10 or 20-year periods
  • Enhanced parameters including turbulence and solar data
