The novel HALO mini-DOAS instrument: inferring trace gas concentrations from airborne UV/visible limb spectroscopy under all skies using the scaling method
We report on a novel six-channel optical spectrometer (further on called mini-DOAS instrument) for airborne nadir and limb measurements of atmospheric trace gases, liquid and solid water, and spectral radiances in the UV/vis and NIR spectral ranges. The spectrometer was developed for measurement...

| description |
We report on a novel
six-channel optical spectrometer (further on called mini-DOAS instrument) for
airborne nadir and limb measurements of atmospheric trace gases, liquid and
solid water, and spectral radiances in the UV/vis and NIR spectral ranges.
The spectrometer was developed for measurements from aboard the German
High-Altitude and Long-Range (HALO) research aircraft during dedicated
research missions. Here we report on the relevant instrumental details and
the novel scaling method used to infer the mixing ratios of UV/vis absorbing
trace gases from their absorption measured in limb geometry. The
uncertainties of the scaling method are assessed in more detail than before
for sample measurements of NO<sub>2</sub> and BrO. Some first results are
reported along with complementary measurements and comparisons with model
predictions for a selected HALO research flight from Cape Town to Antarctica,
which was performed during the research mission ESMVal on 13 September 2012. |
