In this directory:

modified_code: copies of the WRF code that has been changed for
the study. The modified code is also in the WRFV3 directories
where it is called by the Fortran compiler. The comment "! JHR"
appears at the end of each line of modified code.

namelists: namelist files required for both the pre-processing
(WPS) and main WRF model simulations (WRFV3).

start_data: files containing the initial and boundary
conditions necessary to run all WRF simulations.

WPS: code for running WRF pre-processing, i.e., to generate the
files located in directory start_data.

WRFV3: the code to run the Control simulations and tests with
cloud-radiation forcing removed ("NOCRF-*h").

WRFV3_IRCRF_maria: identical to "WRFV3" except the code in
phys/module_ra_rrtm.F is modified to impose cloud-radiation
forcing as a function of radius, given hourly TC location
specified therein based on the hourly TC location from the
Control simulation for Maria (this code directory is
therefore only valid specifically for this experiment).
