Make Better Decisions About Climate Variability

Primary Uses

  • Efficient and easy resource prospecting
  • Setting customer expectations
  • Performing red flag analysis
  • Prioritizing leads and potential sites

Whether you are performing a long-term energy assessment for a single wind project or an entire wind project portfolio, the 3TIER Wind Time Series and Prospecting Tools provide access to multiple long-term reference points for any project location at a flat low price. Understanding the uncertainty of your long-term correction is critical when evaluating project locations. To help in this analysis, the Wind Time Series Tools enable you to visualize NNRP, ERA-I, and MERRA reanalysis datasets side-by-side, and then download one or more of the full hourly time series into your own analysis tools. In performing our long-term energy assessments, 3TIER routinely compares how the long-term corrections of the major reanalysis datasets agree or disagree. The 3TIER Wind Time Series Tools now give you the power to easily access this same information from your browser. The Wind Prospecting Tools help identify the best wind development areas for closer evaluation. These tools offer unlimited access to detailed resource information from our 5 km global wind dataset.

Fast Access to Wind Resource Data

The Wind Time Series and Prospecting Tools save you time and improve your analysis so you have a more complete understanding of wind potential at your next site. They allow you to quickly explore wind resources worldwide without having to do visit sites. The basic subscription level gets you access to 1,000 downloads of time series data and unlimited access to the Prospecting Tools for one flat price.

Long-Term Context For Your Site

Featuring a user-friendly point and click interface, the Wind Time Series Tools offer fast access to detailed resource information from multiple reanalyses datasets. Browse the available wind speed map for your location then use the timeseries viewer to see how the different reanalyses datasets differ over the last couple years or whole decades. When you've decided on a particular location you can download one or more time series with just the click of a button. The hourly time series data will be delivered to your account within hours and there's no limit on how many you can order at one time.

Easy Site Analysis and Comparison

3TIER's Wind Prospecting Tools offer a highly customizable Dashboard interface that makes analyzing and comparing sites, both side-by-side and at multiple hub heights, intuitive and simple. With a more robust set of information, prioritizing leads and potential sites has never been easier. Obtain any site's annual and monthly mean wind speed values and view wind speed distribution with the click of your mouse. Understanding seasonal variability is essential in determining initial site suitability because it helps evaluate how wind resources will perform throughout the year. The Wind Prospecting Tools also include an annual mean wind rose to show you a site's prevailing wind direction. This helps aid in early stage planning about met tower and turbine orientation.

Product Highlights

Access to 3TIER Dashboard tools

Tailor the way you see information to the specific needs and demands of your work all within a seamless, drag and drop interface featuring page layout options, maximize and scale tools, and multiple page views.

Wide Geographic Availability

Select the region you want to explore from the entire globe. With worldwide coverage, these global datasets have few constraints. If you want to develop there, we can provide you the tools to get started. The Prospecting Tools have global coverage between 60 degrees North and 60 degrees South. ERA-I and MERRA time series data are available from pole-to-pole. The NNRP-D data is available for much of the world but not all locations, regions available include the United States, South America, Europe, North and South Africa, the Middle East, Central and East Asia, and Australia.

Delivery Method

Time Series and Prospecting tools are made available via a client-specific dashboard interface. Time series data selected for download will be delivered to client's secure Downloads page on the 3TIER website.


Wind Time Series Tools:

3TIER has made it easier to compare multiple reanalyses datasets by processing the various datasets so they are all temporally interpolated to an hourly resolution, all at the same 100m hub height and they are horizontally interpolated to be point specific. The hourly values of each long-term data set have been scaled to match the long-term mean of 3TIER's Prospecting Tools dataset, which covers the globe at a resolution of 5km and from the time period from 1997 to 2006.

Datasets Available

  • NNRP-D: Downscaled NCEP/NCAR Global Reanalysis Product
  • ERA-I: ERA-Interim Reanalysis Product from the European Centre for Medium-Range Weather Forecasts
  • MERRA: NASA Global Reanalysis Product

Wind Prospecting Tools:

The Wind Prospecting Tools are made possible by the most comprehensive and geographically complete wind dataset available. Founded on the latest science, the dataset was created through the application of advanced NWP (Numerical Weather Prediction) models and incorporates publicly available observations from meteorological towers worldwide. 3TIER's methodology is based on proven, state-of-the-art methods supported by a large scientific and research community and the result was over a decade of simulations for wind resource data.

Technical Highlights
  • Spatial resolution of 2 arc minutes (approximately 5 km)
  • Validated by 4000 NCEP-ADP network stations worldwide
  • Mesoscale 10-year WRF (Weather Research and Forecasting) model run
  • Model constrained by high-quality inputs from the NCAR/NCEP reanalysis, which incorporates real observational data.
  • Validation Results: The difference between annual mean wind speed data provided by the Wind Prospecting tools and actual on-site measurements from NCAR/NCEP reanalysis is less than 0.5 m/s at 50% of the observational stations and less than 1 m/s at 78% of the stations. The overall bias is +0.05 m/s relative to NCEP-ADP observations, and the RMSE (Root Mean Square Error) is 0.93 m/s.
