UV / VIS / NIR ground-based remote sensing
A series of major trace constitutes in the atmosphere (e.g. ozone, nitrogen dioxide, formaldehyde, aerosols) interact with incoming solar radiation attributed to extinction processes in the UV (ultra violet), VIS (visible) and NIR (near infrared) spectral region. We quantify these processes applying differential optical absorption spectroscopy (DOAS) on direct and scattered solar radiation caught by ground-based sensors. This approach allows to retrieve column and profile information of trace gases as well as aerosol and cloud properties. Our goal at ACInn is both to refine common approaches and to invent new concepts for measuring and retrieving trace constitutes from the ground.
