The spectrograph covers a wavelength range of roughly 290–447 nm, operating at a stable detector temperature lower than the air temperature. The operating detector temperatures in Lhasa were set as −10 °C in winter and 0 °C in other seasons. At a specific operating temperature, the ...
It should be noted that each measured spectrum was corrected for dark current and electronic offset and the Fraunhofer reference spectrum was spectrally calibrated by using a highly resolved solar spectrum [52]. Figure 2 shows examples of the spectral retrievals for O3, NO2, BrO, and OClO, ...
