Re: HRRR surface data only available to 18h?


Thanks again for your time and your explanation. All sounds good.

Greetings Ian,

It looks like the data only go out 18 hours. For example, the time variable associated with Geopotential_height_surface goes out to 1080 Minute since 2017-11-27T18:00:00Z :

This looks to be somewhat variable between runs, and likely reflects the experimental nature of the HRRR grids coming from GSD. From my understanding, as new features or GRID outputs are added, it is possible that the run takes more than the allotted time (something less than an hour), and if the processes are not finished, everything is canceled so the next run can begin. I believe this (working out the timing of the run) is part of the normal process and has to be worked out before new stuff goes to NCEP.

Hi Sean,

We are happily downloading HRRR pressure-level data and some surface data, but I am unable to download subsetted surface data past the 18 hour forecast period.

If I put this URL in a browser:


this is returned:

Requested time 2017-11-28T15:00:00Z does not intersect actual time range 2017-11-27T18:00:00Z - 2017-11-28T12:00:00Z

Is there a way to get the surface data beyond the 18hr forecast (ideally out to 36hr) and expand the âactual time rangeâ?

thanks again for your help!
