eCast

Probabilistic 15-Day Weather Forecast Tool

ISO's AER, provides advanced weather-prediction services for industries where weather is a factor in the decision-making process. Whether you’re evaluating energy demand over the next two weeks, purchasing an instrument to transfer your weather risk, or deciding when to deploy your claims-handling resources after an extreme-weather event, AER has a forecast tool for you.

Our flagship product, eCast, is a probabilistic 15-day weather-forecast tool that processes and statistically interprets an ensemble of more than 41,000 forecasts per city per day. Used by energy and weather derivatives traders to minimize risk, eCast provides the forecast you need along with the degree of certainty associated with the forecast.

eCast forecasts are based on physical models, with no influence from climatology. The system captures and preserves data on extreme conditions — extreme cold, extreme heat, extreme rainfall — the very types of weather that affect you the most.

AER’s easy-to-use web interface lets you immediately identify extremes and gauge their degree of certainty for your specific cities of interest, whether in the United States or Europe. You can customize the screens to display only what you want to see from a selection of forecast parameters, including:

  • daily maximum, minimum, and mean temperature
  • heat index
  • wind chill
  • rainfall rate, from trace to moderate

Whether you’re deploying adjusters or claims crews after an event or monitoring extreme conditions to position your workforce or assets before an event, eCast is the tool for you. Developed and supported by AER scientists with recognized expertise in numerical weather prediction, ensemble modeling techniques, bias correction, and statistical methods, eCast forecasts have better accuracy than forecasts from the government and other providers.
