Source Distribution Layout
--------------------------
 The top level of the source code distribution contains the following 
 subdirectories:

   bin    	-- Scripts for maintenance, execution, compilation.
   src    	-- Source.
   aux_src	-- Auxiliary codes. 
   extra	-- Convert emiss for WRF and some dataset.
 

This is the main directory for the PREP-CHEM-SRC source code release
--------------------------------------------------------------------

V1.8.3 Release Notes:
--------------------

- AeM_emission_factors.f90 contains updated emission factors based on studies conducted only in South America.
  AeM_emission_factors_Global.f90 contains updated emission factors based on studies conducted over the world.

- CITES_MOBILE_URBAN_EMISSIONS_FILE. TThis new parameter, avaiable in version 1.8.3 allows to choose the .asc file for Urban emissions, 
  eg: SA_citiesMobileUrbanEmissions.asc, SA_citiesMobileUrbanEmissionsUserDefined.asc, and so on. Before version 1.8.3 the file name was
  fixed as SA_citiesMobileUrbanEmissions.asc

- STREETS_INVENTORY_REGION. During the Olympic Games in Rio de Janeiro in 2016, the "Streets Inventory" functionality was implemented, 
  which allows the use of parameterization of emission-generating streets for  the city of Rio de Janeiro. However, to enable such functionality, 
  you had to enable the parameter in the code. In order to be able to change the parameter without the need to recompile the code, the parameter 
  "streets_inventory_region" was created. Until the current version it may receive the values "RJ" or "NONE". The value "RJ "enables 
  functionality for Rio de Janeiro, and the value" NONE "keeps the functionality disabled. As it was implemented, the parameter allows to 
  implement other configurations of cities, which can be determined in the parameter.

Third Party Software Requirements
---------------------------------


 1. ZLIB 1.2.5(libz.a) or later  distribution.  You may download the software
    from the http://www.zlib.net/ site.
    
 2. HDF5-1.8.8(libhdf5_fortran.a, libhdf5hl_fortran.a) or later  distribution.  You may download the software
    from http://www.hdfgroup.org/HDF5/release/obtain5.html.
    
 3. NetCDF 4.1.1 (libnetcdf.a).  You may download the software
    from http://www.unidata.ucar.edu/downloads/netcdf/netcdf-4_0_1/index.jsp
    

Configuring/Installing HDF 5
------------------------------

When compiling PREP-CHEM-SRC codes on a Linux system using the PGI (Intel)
compiler, make sure the netCDF and HDF* library has been installed using the same PGI (Intel) compiler.

FC=pgf90 CC=pgcc CXX=pgc++ ./configure  \
	--prefix=/path_libs/hdf5-1.8.8 \
	--with-zlib=/path_libs/zlib-1.2.5  \
	--disable-shared \
	--enable-fortran

make
make check
make install
make check-install


INSTALL ZLIB

FC=pgf90 CC=pgcc ./configure --prefix=/path-zlib-1.2.5

make
make check
make install

INSTALL NETCDF

FC=pgf90 CC=pgcc CXX=pgc++ ./configure --prefix=/path-netcdf-4.1.1

make
make check
make install

Configuring/Installing PREP-CHEM-SRC 
------------------------------

Copy files from extra/UserData to your user_data_dir sets into prep_chem_src.inp

cd bin/build
make OPT=opt.pgi CHEM=RACM

Using PREP-CHEM-SRC-1.4 with WRF-Chem V3.4.1
------------------------------

For additional information please consult the WRF-Chem Version 3.4 User's Guide, available at:
http://ruc.noaa.gov/wrf/WG11/Users_guide.pdf

PREP-CHEM-SRC-1.4 partitions anthropogenic and biomass burning NOx emissions into NO and NO2 as follows:

Anthropogenic (EDGAR, RETRO):
NO=0.7*NOx, NO2=0.3*NOx (by mass)
Biomass burning (3BEM, GFEDv2)
NO=0.4*NOx, NO2=0.6*NOx (by mass)

These ratios are based on tests for South America, and you may want to modify them depending on your local emissions profile.

(1) Compiling PREP-CHEM-SRC-1.4 for WRF-Chem (RADM/GOCART speciation)

cd bin/build

make OPT=gfortran.wrf CHEM=RADM_WRF_FIM
or
make OPT=intel.wrf CHEM=RADM_WRF_FIM
or
make OPT=pgi.wrf CHEM=RADM_WRF_FIM


(2) Running PREP-CHEM-SRC-1.4

Edit the input file: prep_chem_sources.inp. The following options should correspond to the Lambert map projection settings in namelist.wps: NINEST=i_parent_start, NJNEST=j_parent_start, POLELAT=ref_lat, POLELON=ref_lon, STDLAT1=truelat1 and STDLAT2=truelat2. CENTLAT and CENTLON are not used for WRF.
Run PREP-CHEM-SRC-1.4 for each day to produce the anthropogenic+biogenic (-ab.bin), biomass burning (-bb.bin), and optional GOCART (-gocartBG.bin) emissions:
./prep_chem_sources_RADM_WRF_FIM.exe

(3) Convert emissions for use in WRF-Chem

For WRFV3.3 only:
The standard WRFV3.3 release reads RADM emissions of only NO, not NO2, and will not work as-is with PREP-CHEM-SRC-1.4. To use PREP-CHEM-SRC-1.4 emissions in WRF-Chem V3.3, please do the following:
(a.1) Place the included files (./extra/WRFChemNO2) into the WRFV3.3/chem directory: module_plumerise1.F, module_add_emiss_burn.F, convert_emiss.F. Also, place the included registry.chem into the Registry directory. 
(a.2) For WRFV3.4.1 don't need copy WRFChemNO2 folder.

(b) In the WRFV3.4.1 directory, compile WRF-Chem and convert_emiss.exe:
./compile em_real
./compile emi_conv

For each day ($year-$mo-$day-00): 
Run real.exe with chem_opt=0 and start and end time set to $year-$mo-$day-00 to generate a wrfinput_d01 file with timestamp for that day.
./real.exe

Link PREP-CHEM-SRC-1.4 emissions to WRF run directory:
ln -sf PREP-CHEM-SRC-1.4/bin/WRF-$year-$mo-$day-000000-g1-gocartBG.bin wrf_gocart_backg
ln -sf PREP-CHEM-SRC-1.4/bin/WRF-$year-$mo-$day-000000-g1-ab.bin emissopt3_d01
ln -sf PREP-CHEM-SRC-1.4/bin/WRF-$year-$mo-$day-000000-g1-bb.bin emissfire_d01

Run convert_emiss:
../chem/convert_emiss.exe

Rename output to include the date:
wrfchemi_d01 wrfchemi_d01_{$year}-$mo-${da}_00:00:00
mv wrffirechemi_d01 wrffirechemi_d01_{$year}-$mo-${da}_00:00:00
mv wrfchemi_gocart_bg_d01 wrfchemi_gocart_bg_d01_{$year}-$mo-${da}_00:00:00

To generate emissions for more than one domain, repeat the above steps for each domain as if it were domain 1 (eg., change nx, ny, dx, dy in the d01 column in namelist.input to those for the subdomain), and rename the output files to include the domain number:
mv wrfchemi_d01 wrfchemi_d<domain>_{$year}-$mo-${da}_00:00:00
mv wrffirechemi_d01 wrffirechemi_d<domain>_{$year}-$mo-${da}_00:00:00
mv wrfchemi_gocart_bg_d01 wrfchemi_gocart_bg_d<domain>_{$year}-$mo-${da}_00:00:00

(4) Running WRF-Chem
Run real.exe to generate wrfinput_d<domain> and wrfbdy_d01 with chemistry.

First, double-check your namelist settings:

&time_control
