I've stopped the grib download process because the game is stuck on Friday 18Z.

ok. This is related to topic "NOMADS maintenance tomorrow" i guess?

Probably. The maintenance broke some of the data access services. I'm using plain https access and can still get the data, but it's useless right now.

Is any difference between all.grib and gfs or other models or which are same? What model is takes into account in the game?
Does the all grib contens waves forecast? Does the game take currents into account?
Does the game take waves into account?

I dont want to start new topic - so I put them here

Thanks
Tom

GRIB is just a data format. Like .jpg or .zip

all.grib is GFS. As is the game. It's the only global model available for free (ECMWF is like $100000/year, winds only)

10m wind only. as is the game. There was an attempt to add tides/currents years ago, but it did not work very well.

I compare all grip and gfs(10m) and there were differenciess +- even 3 to 5 deg and +- 4 kn wind. All.grib was more acurate to the game.... Do you know why?

There should not be any differences between all.grib and the corresponding GFS grib files from the same model/offset.

Game applies additional conversion/rounding.

all.grib is just concatenation of all the individual grib files. Which are the original GFS data, converted to grib v1.
