        An aerosol is the suspension of small solid particles or liquid droplets in the atmosphere.
        https://en.m.wikipedia.org/wiki/Aerosol
        Wind is the displacement of the air due to pressure differences.
        So you can have a strong wind with a small aerosol content or a high content of aerosol with a light wind. Consequently there is no connection between wind and aerosol.

            Why are winds ( vectors moving on the screen) in the option Aerosols , quite different from vectors in Winds or others options, at the same time in forecast ?

            PM2.5 or NOx , for instance, have the same winds and vectors on the screen

            THANK YOU

              Hmm! maybe is a bug here!
              Developers must see that ...
              at the same forecast time (e.g. Tue 16/09Z)
              For "wind": particles animation show a circular motion
              over location A (Fethyie) and Northerly winds over B (Rodos)
              while for "aerosol" the circular motion is located over B.

                It seems that the wind direction in Aerosol layer is similar to the wind direction at 850hPa (~1500m).
                The Ozone layer shows also a wind different from the wind at surface. It seems similar to the wind direction at 150hPa (~13500m).
                I have not checked everywhere and I don’t know why there are such particularities.
