We use the ultra-violet (UV) spectra in the range 230–300 nm
from the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY
(SCIAMACHY) to retrieve
the nitric oxide (NO) number densities from atmospheric emissions in the gamma-bands
in the mesosphere and lower thermosphere.
Using 3-D ray tracing, a 2-D retrieval grid, and regularisation
with respect to altitude and latitude, we retrieve a whole
semi-orbit simultaneously for the altitude range from 60 to 160 km.
We present details of the retrieval algorithm, first results,
and initial comparisons to data
from the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS).
Our results agree on average well with MIPAS data and are in line with
previously published measurements from other instruments.
For the time of available measurements in 2008–2011, we achieve a vertical
resolution of 5–10 km in the altitude range 70–140 km and a horizontal
resolution of about 9° from 60° S–60° N.
With this we have independent measurements of the NO densities in the
mesosphere and lower thermosphere with approximately global coverage.
This data can be further used to validate climate models or as input for
them. |
