COSPEC Correlation Spectrometer Remote Sensors
SO2 and NO2, gases selectively and characteristically absorb light from scattered solar radiation (skylight) as it passes through the
atmosphere. By correlating the resulting absorption spectrum with corresponding reference spectra etched onto a disc inside the unit, the
COSPEC measures, in real time, the integrated concentration of SO2 or NO2 along the line of sight, independently of the presence of
other potentially interfering gases.
The COSPEC, incorporating a unique proprietary mask design, has a high signal to noise ratio and is sufficiently sensitive to track plumes
over great distances under adverse weather conditions. Internal signal processing compensates for changing ambient light levels and
diurnal spectral shifts.
Over 180 COSPECs are currently in use worldwide.
