  skos:definition """A AIRBOURNE TRACKING SUNPHOTOMETER measures the atmospheric
aerosol optical depth. The six separate detectors view the Sun
simultaneously at six independent wavelengths. The FOV of each
detector is set by the entrance aperture to 4 degrees. The
inside surfaces of the aperture assembly are anodized a dull
black to reduce internal reflections; direct sun and sky
radiances are acquired as well."""@en ;
