The dimensions for each of these STASH items is 2D global in longitude and latitude but there is also a third dimension containing 6 pseudo levels for the 6 monochromatic AODs stored by the model.
The standard settings for these are to store AOD at 0.38, 0.44, 0.55, 0.67, 0.87, 1.02 micron wavelengths although any wavelength can be set by modifying the values set in the RADAER fortran code.
