FINN Emissions

The executable finn2cmaq, is a fortran program that grids FINN fire emissions to the required input formats and grids for CMAQ model.

Dependencies

• Fortran GNU compiler.
• NetCDF library.

Get FINN data

Emissions files are produced by Christine Wiedinmyer and are available from NCAR ACOM FINN webpage

A shell script for automated downloading this data is included in this repository: > ./get_finn_data.sh

Build

Edit the Makefile to set the compiler and path to NetCDF lib and include files. Check your nc-config --libdir and nc-config --includedir.

> make

If the compilation is successful, the executable finn2cmaq.exe should be created.

Run

Edit the 'example.inp' that contains the following variables:

&control

start_date="2019-01-01",                        !%Y-%m-%d (YYYY-MM-DD)
  end_date="2019-01-01",                        !%Y-%m-%d (YYYY-MM-DD)

finn_data_directory = './finn_data/'            !path to directory with data

griddesc_file="./GRIDDESC",                     !path to GRIDDESC
gridname= "LCC_TAN_TEST",!"LCC_SEC_TEST", !'MERC_TEST',!

chemistry="GEOSchem",                           !"GEOSchem" / "MOZ4" / "SAPRC99"

diurnal_cycle=0.0043,0.0043,0.0043,0.0043,0.0043,0.0043,0.0043,0.0043,0.0043,0.0300,0.0600,0.1000,0.1400,0.1700,0.1400,0.1200,0.0900,0.0600,0.0300,0.0043,0.0043,0.0043,0.0043,0.0043
/

Note that the variables must be adjusted to match the appropriate values for your system.

Then execute finn2cmaq:

> finn2cmaq.exe < example.inp
