Forecasting the Arrival of ICMEs at 1 AU:
The Drag-Based Model


Full description about the calculation method you can find here. PDF

CME take-off date:
CME take-off time: h min
R0 - starting radial distance of CME (Rs)
v0 - speed of CME at R0 (km/s)
γ - drag parameter (10-7 km-1)
w - asymptotic solar wind speed (km/s)
