Figure: SPATRAM (Spectrometer for Atmospheric TRAcers Monitoring) installed since April 2004 at the University of Evora , Portugal.
Since 1999, DTA is involved in the development of new remote-sensing equipment, in particular Uv-Vis Spectrometers (Figure), devoted to the monitoring of atmospheric compounds (specifically, gaseous compounds as Nitrogen Dioxide (NO2), Ozone (O3) in the Stratosphere and in “passive mode” (meaning that the source of radiation is the Sun). The spectrometers used in “Active Mode” (the source of radiation is artificial – i.e. Halogen Lamps) can also perform measurements of tropospheric pollutants as BTX, Sulphur Dioxide (SO2) and again NO2 and O3.
