Matching WRF and MPAS physics

[ArashC]

Hello,

Sorry for the basic question but I was a bit confused by MPAS manual. Is it possible to exactly match the physics options for WRF and MPAS? I already have a WRF namelist and I want to use the same physics schemes for my MPAS run. Thanks so much.

Best,

Hi,
Many of the same physics that are available for WRF are also available for MPAS, but not all. See this page, which describes supported physics suites, but if you scroll down further, information on the individual available physics options for MPAS are listed.

The physics suite "Mesoscale_reference" corresponds to the suite "Tropical" in WRF. However, some other options should also be set to make the physics consistent between the two models. Below is a detailed list:
config_o3climatology = True (MPAS) and O3input = 2 (WRF)
config_microp_re = True (MPAS) and use_mp_re = 1 (WRF)
config_gwdo_scheme = off (MPAS) and gwd_opt = 0 (WRF)
sfc_snowalbedo = true(MPAS) and rdmaxalb=true (WRF)
Please let me know if you ahve more questions. Thanks.

Thank you so much. Is there a way to also make "convection_permitting" in MPAS equal to physics in WRF?

 

[Ming Chen]

"convection_permitting" in MPAS is equivalent to 'CONUS' in WRF.

Thanks so much. Do I need to implement the following as well?

config_o3climatology = True (MPAS) and O3input = 2 (WRF)
config_microp_re = True (MPAS) and use_mp_re = 1 (WRF)
config_gwdo_scheme = off (MPAS) and gwd_opt = 0 (WRF)
sfc_snowalbedo = true(MPAS) and rdmaxalb=true (WRF)

Yes you need to specify these options, no matter what suites you use.
