Regarding running new AiGFS, AIGEFS and HGEFS using WRF

Hello,

In the upcoming conference we want to publish a paper regarding new AIGFS, AIGFS and HGEFS model. For that we want to use WRF to downscale the data. We downloaded the GRIB file of that three model. But after running geogrid and for ungrib we Vtable for that 3 model. Is there any Vtable file for that. We tried to run using GFS table but its does not work. Also, is there any way to downscale that please inform us.

Thank you.

Thank you.
might have to be developed by ncar
 
We have created Vtable file for AiGFS and HEGFS. But the problem is that these two input data is missing important variable that need to be available to run WRF. If it hase complete variable I think we can ran WRF for these two input data.

There is another solution is that merge the AIGF or HEGFS data with GFS data for complete variable list.

Which variable? Have you dump the files headers to see if it's just a different label?

We've ran into a similar situation with ecmwf
 

Key Finding: AIGFS Has Limited Variables​


After inspecting the actual AIGFS GRIB files, I found that AIGFS is a very stripped-down dataset compared to GFS:


What AIGFS Provides:​


VariableLevels
Temperature (TT)Pressure levels + 2m
U/V Wind (UU, VV)Pressure levels + 10m
Specific Humidity (SPECHUMD)Pressure levels only
Geopotential Height (HGT)Pressure levels
Vertical Velocity (OMEGA)Pressure levels
Mean Sea Level Pressure (PMSL)Surface
Total PrecipitationForecast hours

Pressure levels: 1000, 925, 850, 700, 600, 500, 400, 300, 250, 200, 150, 100, 50 hPa


Critical Variables MISSING from AIGFS:​


  • Surface Pressure (PSFC) - only MSLP available
  • Soil Moisture (all 4 layers)
  • Soil Temperature (all 4 layers)
  • Land/Sea Mask
  • Sea Ice
  • Terrain Height from source analysis
  • Skin Temperature
  • Snow

    As you can see, these are the situation for the AIGFS DATA.
