From: Aeolus winds impact on volcanic ash early warning systems for aviation
Wind speed differences in WRF 18 h forecasts (“w”–“w/o” Aeolus assimilation). (Upper panel) horizontal winds at 300 hPa (~ 9.6 km); the solid black line indicates the Aeolus orbit path (overpass on 12th of March 2021, 05:01 UTC); (Lower panel) vertical cross-section over the dashed red line denoted in the upper panel (from Etna towards the Middle East); the arrows in both panels are horizontal wind speed components with green denoting “w” Aeolus and black denoting “w/o” Aeolus; the color shading in both panels illustrates the differences in wind speeds between the two WRF runs.
