Time Series Data

The Weather Research and Forecasting (WRF) model has been the model of choice at UL Solutions to generate meteorological time series. Time series spanning 10 or 20 years are often used to adjust short-term onsite measurements to the long-term wind climate (often with Measure-Correlate-Predict), to create a typical meteorological year time series, to estimate the wind speed fluctuations from year to year, i.e., inter-annual variability (IAV), to provide necessary meteorological inputs to icing modeling, time series energy modeling, etc.

• High-resolution 3km grid spacing
• Choose 10 or 20-year periods
• Temporal resolution of 1 hour, 15-minute or 10-minute
• Enhanced parameters including turbulence and solar data
• Up to 10 points within a single WRF order

Two reanalysis datasets providing historical meteorological time series going back to 1979 or 1980 are offered, namely NASA’s second version of the Modern Era Retrospective-Analysis for Research and Applications (MERRA-2) and ECMWF’s fifth generation atmospheric reanalysis (ERA5). Reanalysis datasets are primarily used for long-term wind climate adjustment together with short-term (> 1 year) wind observations at a site.

• Global coverage with decades of historical data
• Multiple meteorological parameters
