Observations of volcanic SO2 from MLS on Aura
Summary: Volcanic eruptions can be violent enough to inject sulfur dioxide into the stratosphere: the layer of the atmosphere which contains the ozone layer. Sulfur dioxide is a gas, but once it is in the stratosphere various chemical reactions convert it into tiny particles. These particles can alter the Earth's climate by reflecting sunlight. In this paper we describe how we used a satellite instrument called the Microwave Limb Sounder to observe volcanic sulfur dioxide in the stratosphere.

Global investigation of the Mg atom and ion layers using SCIAMACHY/Envisat observations between 70 and 150 km altitude and WACCM-Mg model results
Summary: Global concentration fields of Mg and Mg+ in the Earth's upper mesosphere and lower thermosphere (70-150km) are presented. These are retrieved from SCIAMACHY/Envisat satellite grating spectrometer measurements in limb viewing geometry between 2008 and 2012. These were compared with WACCM-Mg model results and a large fraction of the available measurement results for these species, and an interpretation of the results is done. The variation of these species during NLC presence is discussed.

Atomic oxygen retrievals in the MLT region from SCIAMACHY nightglow limb measurements
Summary: This paper deals with the retrieval of atomic oxygen concentration profiles in the Earth's upper mesosphere/lower thermosphere region from SCIAMACHY observations of oxygen green line airglow emissions. Atomic oxygen is one of the most important chemical constituents of this atmospheric region, and long-term satellite data sets are rare. The paper includes a detailed description of the retrieval algorithm, an error budget, validation results and some first scientific analyses.

Gauss–Seidel limb scattering (GSLS) radiative transfer model development in support of the Ozone Mapping and Profiler Suite (OMPS) limb profiler mission
Summary: The Gauss--Seidel limb scattering (GSLS) radiative transfer model simulates the transfer of solar radiation through the atmosphere. Several recent changes have been added that improve the accuracy and flexibility of the GSLS radiance calculations. The single-scattered radiance errors have been reduced from 4% in earlier studies to 0.3%, while total radiance errors generally decline from 10% to 1-3%. In all cases, the tangent height dependence of the GSLS radiance error is greatly reduced.

GOMOS bright limb ozone data set
Summary: A novel daytime ozone profile data set was created from the measurements of the Global Ozone Monitoring by Occultation of Stars (GOMOS) instrument on board the Envisat satellite. These stratospheric ozone profiles cover the years 2002-2012 with good accuracy, vertical resolution, and global coverage.

Relative drifts and biases between six ozone limb satellite measurements from the last decade
Summary: The analyses among six satellite instruments measuring ozone reveals that the relative drift between the sensors is not significant in the stratosphere and we conclude that merging of data from these instruments is possible. The merged ozone profiles can then be ingested in global climate models for long-term forecasts of ozone and climate change in the atmosphere. The added drift uncertainty is estimated at about 3% per decade (1 sigma) and should be applied in the calculation of ozone trends.
