2.5 Scientific parameters
Your Calitoo is sold calibrated. The calibration parameters are stored in the
photometer and are visible on the web site
www.calitoo.com
, in the Calibration
tab.
Be careful if you change these values, knowingly or after a new calibration or if
you notice any differences with calibration parameters online. .
To send the new values to photometer you have to edit it and to click on the
submit button.
They will be stored in the photometer even after a power off and used for
calculations of optical thicknesses of the new measurements.
Measurements made before this change will remain unchanged. If these must be
rectified, the only way is to redo the calculations with the
AOT Processing
tool
described below.
Parameters are:
•
No
: is the numerical value that give your photometer if it came out of the
Earth's atmosphere (Figure 6).
•
Rayleigh
: is a coefficient that takes into account the distribution of light
at a specific wavelength by the molecules of the clean air.
•
Ozone
: is the contribution of stratospheric ozone to the optical thickness.
It is zero for blue.
