Sensor functionalities
Students point a sun photometer at the sun, and record the highest voltage reading that they obtain on a digital voltmeter connected to the photometer.
Measure the aerosol optical thickness of the atmosphere (how much of the sun’s light is scattered or absorbed by particles suspended in the air).
The values of AOT are calculated automatically when data are entered through GLOBE data entry page.
