finn2cmaq's Introduction

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
