3.6 AOT processing
3.6.1 Principle
The processing of AOT data retrieves old measurements and re-calculate the
optical thickness based on new calibration coefficients.
This will usually happen after a new calibration of the photometer. It can also be
carried out on an experimental basis.
3.6.2 Re-calculation with software
After loading the data you want to work with, into the computer, click the tool icon
AOT Processing
.
The software displays the original AOT curves (dotted) and the curves recalculated
from current coefficients in solid lines.
Here's what can be achieved on the screen :
3.6.3 Change settings
The role of the parameters is quickly and easily readable: the curves are redrawn
every variation of parameters.

The coefficients of Rayleigh and ozone only with an editor.
Visualization of curves
However, for a re-calculation of AOT, you do not have a setting to change and they
have already been updated with the new calibration.
