NDACC Brewer spectrophotometer no. 010 total ozone column data from DWD Hohenpeissenberg station

Total Column of Ozone (TCO) measured from Brewer spectrophotometer no. 010. The Brewer spectrometer is a fully automated system. To derive total ozone columns, it measures solar irradiance at six nominal wavelengths in the UV range, from 303.2 to 320.1 nm, quasi-simultaneously. This is achieved by using a slit mask in combination with a holographic grating and a photomultiplier tube. The calculation of TCO uses measurements only at the four longest wavelengths of the six.
