Contents0. This file 'README'

1. Emission profiles for ash and SO2 (in pickle and txt format).   1.1 Files 'ash_2d_emission_profiles' [Mt/sec] and 'ash_2d_emission_profiles.txt' [Mt/(m sec)]   1.2 Files 'so2_2d_emission_profiles' [Mt/sec] and 'so2_2d_emission_profiles.txt' [Mt/(m sec)]

2. python script 'draw_supplementary_profiles.py' plots inverted emission profiles    (in pickle format) and their time integrated variants.

3. WRF-Chem output file 'wrfout_d01_1991-06-16_00:00:00' in netcdf format contains    3-D fields of ash, sulfate, and SO2 concentrations at 0000 UTC on 16 of June.    Instructions on how to process WRF-Chem output are available at the Appendix of [2].

4. WRF-Chem domain grid description in the file 'wrf_small_grid.txt'. This file can be   used for conservative interpolation of 3-D fields to another grid, for example    using 'cdo remapcon'.

There are two options: 1. Use inverted ash and SO2 emission profiles (see p.1 and p.2)2. Use ash, sulfate, and SO2 concentrations from WRF-Chem output file (see p.3 and p.4)   as initial conditions for another run.
