HARMONIE forcing

Accumulated variables : at each time-step the previous time-step values are substracted, with the different treatment of the initial time-step value (see in the brackets for each case)
Instantaneous variables : no treatment applied

1H : 1-hourly forcing created from the forecasts starting at 0h / 6h / 12h / 18h using the time-steps 1 / 2 / 3 / 4 / 5 / 6 (no treatment for the 1st time-step value)
3Ha : 3-hourly forcing created from the forecasts starting at 0h / 12h using the time-steps 6 / 9 / 12 / 15 (from the 6th time-step value the 3rd time-step value is substracted)
3Hb : 3-hourly forcing created from the forecasts starting at 0h / 12h using the time-steps 6 / 9 / 12 / 15 (the 6th time-step value is divided by 2)
3Hc : 3-hourly forcing created from the forecasts starting at 0h / 12h using the time-steps 9 / 12 / 15 / 18 (from the 9th time-step value the 6th time-step value is substracted)
