Operational Probabilistic Fog Prediction Based on Ensemble Forecast System: A Decision Support System for Fog Open
One of the well-known challenges of fog forecasting is the high spatio-temporal variability of fog. An ensemble forecast aims to capture this variability by representing the uncertainty in the initial/lateral boundary conditions (ICs/BCs) …

Fog nowcasting over the IGI airport, New Delhi, India using decision tree Open
In the modeling framework, forecasting fog onset and its dissipation time is challenging work, which typically becomes a threshold problem in very dense fog (50m <Vis < 0m) cases. In addition, poor/inaccurate fog forecasts may create dange…
