HRRR Model 4 years 4 months ago #596

rgraulus Topic Author Offline New Member Posts: 6 Thank you received: 0	Hi, Any plans to add the HRRR model to your server? I know this model is restricted to continental US (CONUS) but the GRIB2 data is made publically available by NOAA rapidrefresh.noaa.gov/hrrr/ Regards Rik

Hi,
Next Xygrib version should be able to read HRRR files (Lambert Conformal projection) and NOAA site offers a sub-setter, maybe Xygrib could download these GRIB directly from NOAA?
Caveats:
- Sub-setter doesn't compress data.
- They change query layout from time to time.

Blend model could be interesting though, there's no sub-setter for it.

Sample in Xygrib:
Stereopolar, Lambert and Mercator GRIB.

Progress is, however, a bit slow as I need to get a thesis completed but we will get there. David

HRRR Model 4 years 3 months ago #633

rgraulus Topic Author Offline New Member Posts: 6 Thank you received: 0	Hi David, Progress is good... I have another question related to HRRR...The model does not have a field for the Aviation Flight Rules (as defined by the FAA). The flight rules ca be calculated from two parameters which are in the model i.e. ceiling and visibility. My question is if your software allows me to create a new field/parameter and add it to the GRIB2 dataset. Please advise. Regards Rik

Resources on this site will always be free and open with no commercialization. However, operating costs of the servers to pre-process and deliver GRIB files to XyGrib are not trivial.
