NOMADS grib file naming

Question

I am looking to run

example on wave model data. It refers to downloading grib files from

When I browse into a current date subfolder, what is the naming convention?

I see

multi_1.ak_10m.t00z.f000.grib2

I assume it must be something like

multi_1.<LOCATION>_??m.t??z.f<FORECAST_IN_HOURS>.grib2

LOCATION I see ak - Alaska? , ep - East Pacific? , glo - Global?

What are the others?

Taking your example:

<LOCATION>_??m : the resolution of the model in (arc)minutes

.t??z : the time of the model run at which it was started

.f??? : the number of hours after the model was started

The locations with corresponding notation can be found here

THanks! When I get data from the Nomads server that has a time tag 11-Oct-2019 03:33, when was it created? Is this UTC / PST time? nomads.ncep.noaa.gov/pub/data/nccf/com/wave/prod/… – El Dude Oct 11 '19 at 18:20

Honestly I'm not sure. Looking at the time stamps I'm inclined to believe it would be UTC but I cannot tell you for certain. Sorry! – thesunnyscientist Oct 11 '19 at 23:13
