TL;DR: In this article, column measurements of stratospheric nitrogen dioxide and OClO made near the arctic vortex were used to study ozone depletion effects in the artic region by looking for atmospheric signatures of gases which contribute to catalyzing ozone depletion and denitrification.

TL;DR: It is shown that the structures, which originate from a Fabry-Pérot etalon, may be removed by tilting the emitter, which at the same time increases the radiant flux coupled into the subsequent optical system.

TL;DR: The successful launch in early 2002 of the SCanning ImAging spectroMeter for Atmospheric CHartographY (SCIAMACHY) instrument on the ESA ENVISAT satellite opened the second phase of a substantial European effort to study trace substances and pollutants in the troposphere with measurements from space as mentioned in this paper.

TL;DR: In this paper, three different remote sensing instruments (a sub-millimeter radiometer, a differential optical absorption spectrometer in the UV-visible spectral range, and a lidar) were deployed aboard DLR's meteorological research aircraft Falcon 20 to validate a large number of SCIAMACHY level 2 and off-line data products such as O3, NO2, N2O, BrO, OClO, H2O and clouds.

TL;DR: With the return of sunlight in the polar spring, the snowpack serves as an effective source of molecular halogens to the Arctic boundary layer as mentioned in this paper, and reactive bromine production and associated ozone depletion is reduced.
