[editar] Aerosol climatologies for Thompson aerosol aware

Since WRF v3.6 there is an option to have a micro-physics scheme with awareness on aersol densities. See more details in Thompson Aerosol-aware.

One need to add at WPS - metgrid, the files with the climatologies of aerosos. These climatologies come from GCM runs where aerosols where active. There are 3 different climatologies (QNWFA_QNIFA_Monthly_AWIP/GFS/ERA), comming from the ue of 3 different re-analysis.

In case of using ERA-Interim re-analyses, on should include on the namelist.wps

&metgrid
 fg_name = 'FILE',
 io_form_metgrid = 2,
 opt_metgrid_tbl_path = './'
 constants_name = 'QNWFA_QNIFA_Monthly_ERA'
/

And then link the climatological fle (in this case the ERA-Interim) where metgrid.exe will be run

$ ln -s /share/GEOG/QNWFA_QNIFA_Monthly_ERA ./

At the namelist.input one should have

mp_physics              = 28
use_aero_icbc           = .T.
aer_opt                 = 3

• use_aero_icbc is used to specify that we want to use the QNWFA_QNIFA_Monthly_* aerosol climatologies
• aer_opt is used to specify that we want the same aerosol climatologies for microphysics and radiation scheme (oonly for RRTMG)

NOTE: Since WRFv3.9 there is a new unique file for the aerosol climatologies QNWFA_QNIFA_SIGMA_MONTHLY
