Starting from WRFV3 version 3.9.1.1

Original code downloaded from:
https://www2.mmm.ucar.edu/wrf/users/downloads.html

Code provided in these directories has been modified as described
below. In WRFV3 directories, copies of modified scripts are
included with the suffix "_JHR", and of original scripts with the
suffix "_ORIG". Copies of each of the modified scripts are also
included in the directory "modified_code".

Changes have only been made for use of RRTM longwave scheme
(ra_lw_physics = 1 in namelist) and Dudhia shortwave scheme
(ra_sw_physics = 1).


Changes:

Added clear-sky longwave and shortwave tendencies (RTHRATLWC, RTHRATSWC), 
OLR (OLRC), and downward LW flux at surface (GLWC) as outputs. These
variables were already calculated by radiative transfer models, so just
needed to be passed up.

Added TC-location information to the longwave scheme in order to impose
cloud-radiation forcing as a function of radius. This TC-location
information is based on the hourly output from the Control simulation
for Maria. While this information is in the code under both WRFV3 and
WRFVR_IRCRF_maria, it is not used in the former.
