2 Meter Minimum Temperature (EFI)
Product Overview
The Extreme Forecast Index (EFI) for the minimum forecasted temperature at a height of 2 meters, given as a number between -1 and 1.
EFI is a measurement of the deviation from the climate norm at that location, where the sign indicates the direction of deviation and the value the amount of deviation.
Absolute values greater than 0.5 indicate unusual weather, and greater than 0.8 that extreme weather is likely.
