AATSR - AERONET aerosol optical depth comparison
A quick comparison between the aerosol optical depth seen from the
Venise AERONET station (the platform) and that given by the ORAC AATSR
retrieval has been done for the 1/9/2004 overpass.
The results are displayed below (click for a larger version):

The plot shows the difference between the AATSR based optical depth
and that given by the station (interpolated to 0.55 microns) over the
northern Adriatic. The location of the station is indicated by the
black star.
Unfortunately most of the area directly surrounding the station has
been flagged as cloudy, however some conclusions can be drawn from
the image. It is clear that the retrieval is not to be trusted over
land, and the effect of approaching the area of sun-glint can be seen
at the right of the swath. However the values over the Adriatic itself
are certainly comparable to those seen from the AERONET site.
