I want to run the premegan4cmaq.growthform.inp and other .inp files and in this file we have the following:
&windowdefs
x0 = 1,
I’m just wondering what are x0, y0, ncolsin and nrowsin mean? Do I need to change them based on my domain?
Thanks@willison.jeff

These parameters are adopted from the MCIP in CMAQ, with the aim of cutting model grids. Thus, these values should be consistent with your MCIP run script. You can refer to the example below, which is for CMAQ benchmark data.

# 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. #
