> Hello Hi Marcelo, This is Jeff, we met in Tuscaloosa... > > I am contacting you to ask what would be the best way to get HRRR data > hourly through IDD/LDM. This is for a project lead by CUAHSI ( > https://www.cuahsi.org/NFIE) and NWS, in which we are planning to run > NCAR's WRF-Hydro software for the cont US. > Yes, aware of this plan :) > The parameters we need are > Incoming Short Wave Radiation (W/m2) > Incoming Long Wave Radiation (W/m2) (I UNDERSTAND THAT THIS IS NOT > AVAILABLE) > Specific Humidity (Kg/Kg) > Air Temperature (K) > Surface Pressure (Pa) > Near surface widn in the u and v components, (m/s) > Liquid water precipitation (mm/s) > Marcelo, I suspect that we can derive Long Wave by subtracting short wave from Net....double checking that net radiation at surface is a parameter, but pretty sure it is. > Also I wonder if you have MRMS precipitation data available. We will have it, NSSL (Nat'l Severe Storms Lab) has brought down the feed for a bit, we expect it to be back in time for NFIE spring/summer workshop...I will keep on that schedule and keep you up to date. > > Currently we are using THREDDS service to get the data ( > http://thredds-jumbo.unidata.ucar.edu/thredds/catalog/grib/HRRR/CONUS_3km/surface/catalog.html); > however, we understand that GSD THREDDS is an experimental system that can > change in any moment and we need an operational system to rely on. > Yes, we are getting both the "operational" HRRR (surface fields) via the IDD/LDM from NCEP AND the experimental HRRR (all levels) from NOAA ESRL/GSD...this is what is on thredds-jumbo currently. I am working on this to insure stability and consistency during the NFIE campaign, I will have more definitive info as we get into next week re the GSD HRRR and the NSSL MRMS feeds... I am in contact with the NOAA people to see if they can freeze modifications during the NFIE campaign and minimize downtime... They are currently doing a major post-processing re-do, so hopefully that will be the last big change for awhile and provide us stability for NFIE.
