3-D tomographic limb sounder retrieval techniques: irregular grids and Laplacian regularisation [PDF]
Atmospheric Measurement Techniques, 2019 Multiple limb sounder measurements of the same atmospheric region taken from different directions can be combined in a 3-D tomographic retrieval. Mathematically, this is a computationally expensive inverse modelling problem.

A comprehensive observational filter for satellite infrared limb sounding of gravity waves [PDF]
Atmospheric Measurement Techniques, 2015 This paper describes a comprehensive observational filter for satellite infrared limb sounding of gravity waves. The filter considers instrument visibility and observation geometry with a high level of accuracy.

How do microorganisms reach the stratosphere? [PDF]
, 2005 A number of studies have demonstrated that bacteria and fungi are present in the stratosphere. Since the tropopause is generally regarded as a barrier to the upward movement of particles it is difficult to see how such microorganisms can reach heights ...

Limited angle tomography of mesoscale gravity waves by the infrared limb-sounder GLORIA [PDF]
Atmospheric Measurement Techniques, 2018 Three-dimensional measurements of gravity waves are required in order to quantify their direction-resolved momentum fluxes and obtain a better understanding of their propagation characteristics.

An Ozone-Modified Refractive Index for Vertically Propagating Planetary Waves [PDF]
, 2007 [1] An ozone-modified refractive index (OMRI) is derived for vertically propagating planetary waves using a mechanistic model that couples quasigeostrophic potential vorticity and ozone volume mixing ratio. The OMRI clarifies how wave-induced heating due

Satellite observations of middle atmosphere–thermosphere vertical coupling by gravity waves [PDF]
Annales Geophysicae, 2018 Atmospheric gravity waves (GWs) are essential for the dynamics of the middle atmosphere. Recent studies have shown that these waves are also important for the thermosphere/ionosphere (T/I) system. Via vertical coupling, GWs can significantly influence

Stratospheric ozone depletion [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 1991 Solar ultraviolet radiation creates an ozone layer in the atmosphere which in turn completely absorbs the most energetic fraction of this radiation. This process both warms the air, creating the stratosphere between 15 and 50 km altitude, and protects the biological activities at the Earth's surface from this damaging radiation.

How stratospheric are deep stratospheric intrusions? LUAMI 2008 [PDF]
Atmospheric Chemistry and Physics, 2016 Abstract. A large-scale comparison of water-vapour vertical-sounding instruments took place over central Europe on 17 October 2008, during a rather homogeneous deep stratospheric intrusion event (LUAMI, Lindenberg Upper-Air Methods Intercomparison). The measurements were carried out at four observational sites: Payerne (Switzerland), Bilthoven (the ...
