- Are the t=0 forecast fields the same as the analysis fields?
- How are data interpolated/transformed to a lower resolution grid?
- How are Large Scale precipitation, Convective Precipitation and Snowfall defined in the ECMWF model?
- How are low, medium and high cloud cover defined?
- How can evaporation have both positive and negative values?
- How can the Geopotential height in metres be calculated?
- How to access the archived forecast data of the 06z and 18z HRES/ENS known as the High Frequency Products?
