The code used for data processing was written with Python programming language version 3.8 (https://www.python.org/)

1. WRF-meteorology.py -> Fig. 2 Upper Panel: Wind speed differences (horizontal winds) in WRF forecasts (“w” – “w/o” Aeolus assimilation) at different isobaric levels.
2. WRF_cross_sections_along_the_plume.py -> Fig. 2 Lower Panel: Vertical cross-section of wind speed differences (“w” – “w/o” Aeolus assimilation) at different isobaric levels from Etna towards the Middle East.
3. plot_WRF_IFS_UV.py -> Fig. 3: Horizontal wind speed differences at different isobaric levels (WRF-IFS "w" (upper panel) and "w/o" (lower panel) assimilated Aeolus wind fields.
4. FLEXPART-MAPS.py -> Fig. 4 (upper panel) 2D total transport.
5. FLEX_vertical_cross_section_AEOLUS.py -> Fig. 4 (lower panel) vertical dimension over the 2D footprints.
6. FLEXPART-MAPS.py -> Fig. 5 FLEXPART simulations of the volcanic ash dispersion.
7. station_height_timeseries_aeolus.ncl -> Fig.6 (middle) time-height cross-section of FLEXPART volcanic ash concentrations over PANGEA observatory in Antikythera, Greece.
8. plot_EARLINET_elic_all_month_mod2022_02_21_Etna_Aeolus.py -> Fig. 7 Vertical distributions.
