I am working on developing a Utah Specific dust model framework using CMAQ and WRF. After reading the paper, "Development and evaluation of a physics-based windblown
Is there a specific set of files in CMAQ that has these values or any other way to possible change this?
Hi,
You want to look into “DUST_EMIS.F” file:
The line numbers below are based on the latest release here:
!------------------------------------------------------------------------!
! The Community Multiscale Air Quality (CMAQ) system software is in !
! continuous development by various groups and is based on information !
! from these groups: Federal Government employees, contractors working !
! within a United States Government contract, and non-Federal sources !
! including research institutions. These groups give the Government !
! permission to use, prepare derivative works of, and distribute copies !
! of their work in the CMAQ system to the public and to permit others !
! to do so. The United States Environmental Protection Agency !
! therefore grants similar permission to use the CMAQ system software, !
! but users are requested to provide copies of derivative works or !
! products designed to operate in the CMAQ system to the United States !
! Government without restrictions as to use by others. Software !
! that is used with the CMAQ system but distributed under the GNU !
! General Public License or the GNU Lesser General Public License is !
! subject to their copyright restrictions. !

That was exactly what I was looking for. Thank you!
