Forecasts

Statistically driven forecasts based upon the GFS & ECMWF models

SuperPack® Subscription


Speedwell SuperPack® (Forecasts) makes available an unprecedented range of high-quality weather forecasts for a single annual fee.

As an enterprise license, all users within a company have unlimited access to our global database of forecast products.

In addition to forecasts, users have access to Speedwell web tools (Forecast Dashboard, FastCast, and the Graphical Forecast Viewer).

Product Highlights


Speedwell downscaled forecasts are location-specific forecasts based upon the ECMWF & GFS forecast models that have been post-processed to remove forecast bias. Bias correction is accomplished by comparing the forecast against observed data and then statistically correcting the forecast. The resulting forecast is generally superior to the original raw model output.

Raw forecasts

Station level forecasts that are produced through interpolation (from model grid points) and the manipulation of model slices to produce the desired temporal resolution (climate day forecasts, gas day…).

  • ECMWF operational (00Z, 12Z), 10-day forecast
  • ECMWF ensemble (00Z, 12Z), 15-day & 45-day forecast
  • GFS operational (00Z, 06Z, 12Z, 18Z), 15-day forecast
  • GFS ensemble (00Z, 06Z, 12Z, 18Z), 15-day forecast

Downscaled forecasts

Raw forecasts that have been processed to detect forecast bias (comparison with surface observations). Forecast bias is calculated continuously for each forecast product, each model run, each element, for each station, and for each day. Once understood, the detected bias is removed from the forecast to produce the downscaled forecast.

    • 3-hourly wind speed (Europe) (ECMWF only)
    • 3-hourly solar radiation (Asia, Europe) (ECMWF only)
    • Hourly temperature (Europe) (ECMWF only)

Speedwell Dashboard

A convenient, intuitive, and powerful web interface for viewing and understanding forecasts.

  • Forecasts for multiple locations viewed in a tabular format
  • Heat map display indicates the forecast departure from climatological normal
  • Box-and-whisker plots (based upon the ensemble forecast) available on a station basis
  • Detailed forecast statistics (forecast range, skewness, and extreme values)
  • Probability density function (based upon the ensemble forecast)

Speedwell FastCast

A frame-by-frame ultra-fast graphical presentation of the change in forecast. Updated as each time step of the model is released.

Graphical Forecast Viewer

Forecast analysis tool designed to provide users with an in-depth understanding of current forecasts as well as post analysis of forecast events.

  • Box-and-whisker plots (based upon the ensemble forecast) available on a station basis
  • Spaghetti plots (based upon the ensemble forecast) available on a station basis
  • Probability distribution plots (based upon the ensemble forecast) available on a station basis
  • Forecast verification

Speedwell Wind Power Production

Each Wind Power Production forecast represents a prediction of hourly energy production (MWh) for a given region (national, regional, or custom portfolio). Wind forecasts are based upon the ECMWF and GFS forecast models and converted to power production using Speedwell Wind Power Production models (the same models used to produce the Speedwell Wind Power Production Indices).

Speedwell Solar Power Production

Each Solar Power Production forecast represents a prediction of hourly energy production (MWh) for a given region (national, regional, or custom portfolio). Solar forecasts are based upon the ECMWF and GFS forecast models and converted to power production using Speedwell Solar Power Production models (the same models used to produce the Speedwell Solar Power Production Indices).

Speedwell Population Weighted Indices

Population weighted indices utilize a basket of surface weather stations to monitor the weather impacting a given population. Forecasts for individual stations are weighted and combined to produce forecasts for the relevant indices. These indices are supported by the full suite of forecast models, most variables, and the Speedwell web tools.

Speedwell Agriculture Indices

Indices used to monitor the weather impacting a given crop within a given region. These indices are based upon surface weather station forecasts that have been weighted and combined to produce daily values of temperature and precipitation. These indices are supported by the full suite of forecast models and the Speedwell web tools.
