ECMWF from Saildocs versus Expedition.
ECMWF 0.25, 6 day fetch from Saildocs optimize/produces a routing solution fine over my route.
Same route and start time. EC HRES 0.25, 6 day fetch from Expedition. Optimize errors with "Unable to continue".
What am I missing?
Cheers

Re: ECMWF from Saildocs versus Expedition.
If you get that message, in this case it is probably because you don't have as many hours in the forecast.
Saildocs only gets the 00 and 12z runs. Exp also gets the 06 and 18z runs, but they don't go as far.
You can also get the previous run from the Exp grib server.
It is worthwhile reading the Expedition weather web page.

Re: ECMWF from Saildocs versus Expedition.
Understood and yes I've reviewed the weather pages. Sure enough, my EC download only went out to H90 which was short for the routing solution.
If I am understanding correctly, a GRIB download requesting X number of days will not throw an error at me if Expedition is unable to download the entire requested time period. Expedition will just download the interval that is available. I do need to pay closer attention to the hours checkbox list.
How exactly does one request download for an older GRIB?

In the Exp 12 there is a check box in the new weather download dialog.

Re: ECMWF from Saildocs versus Expedition.
Obviously all the data may not have arrived yet too. The Run times button is your friend for that.
