Integrated data for ICE/TURB/CB It should be clear for the user how to interpret new data. Each of ICE/TURB should be characterized by single parameter. Thresholds (light, moderate and severe) need to be determined.It should be clear for the user how to interpret new data. Each of ICE/TURB should be characterized by single parameter.

Conclusions It is desirable to get model outputs in terms of physical atmospheric properties (ex. EDR). Each of ICE/TURB should be characterized by single parameter (instead of MEAN and MAX).It is desirable to get model outputs in terms of physical atmospheric properties (ex. EDR).
