Hi Cvetan,

Concerning the weather files and its interpolation.

The GFS 1 ° are available at 00h / 06h / 12h / 18h UTC

I suppose you interpolate them and so you go a step from 06h to 03h?

If so it is wise to make a routing at 00h / 03h / 06h / 09h / 12h / 15h / 18h / 21h UTC

For France: 02h / 05h / 08h / 11h / 14h / 17h / 20h / 23h CEST?


Thanks

The GFS runs every 6 hours, but outputs data with 3-hour resolution, so the 3/9/15 etc hour forecasts are actual NOAA data, not interpolated from the 6-hour files.

That's what the game uses, and I use it too.

Routing should not change every 3 hours, because data does not change so often.

BTW there is one difference between the router and the game, and it is quite visible sometimes. The game uses some interpolation between the old and the new GFS runs for the same point in time, and I use just the new GFS output as it becomes available (because I haven't figured the exact way the game works)

As a result you can see big differences between the game and the router when the forecast is unstable and has changed a lot between two GFS runs. That lasts for about an hour around the start of the weather updates (0h/6h/12h/18h)
