Observation sites

At RADO, active remote sensing instruments (lidars) are used together with integrated column pasive remote sensing ones (sun tracking photometers) and in situ ground-level monitors (for gases and particles). Lidars provides profiles of aerosols, ozone and water vapour up to the stratosphere, so that layer altitudes can be derived. Using 7-9 wavelengths, sun photometers provide more optical parameters, but integrated in the air column. Data obtained from ground-level monitors are used as ground-truth and calibration values. This synergy of point monitor-total column and profiles supplemented by modelling tools and satellite data makes RADO an atmospheric composition distributed observatory.
