The southern part of South America and the Antarctic peninsula are known as the world's
strongest hotspot region of stratospheric gravity wave (GW) activity. Large tropospheric …

Ozone trends in the upper troposphere and lower stratosphere (UTLS) remain highly
uncertain because of sharp spatial gradients and high variability caused by competing …

The radiative energy budget in the Arctic undergoes a rapid transformation compared with
global mean changes. Understanding the role of cirrus clouds in this system is vital, as they …

Bromine released from the decomposition of short-lived brominated source gases
contributes as a sink of ozone in the lower stratosphere. The two major contributors are CH 2 …

During winter 2015/2016, the Arctic stratosphere was characterized by extraordinarily low
temperatures in connection with a very strong polar vortex and with the occurrence of …

In this study, we present simultaneous airborne measurements of peroxyacetyl nitrate (PAN),
ethane (C 2 H 6), formic acid (HCOOH), methanol (CH 3 OH), and ethylene (C 2 H 4) above …

Abstract The Mission Support System (MSS) is an open source software package that has
been used for planning flight tracks of scientific aircraft in multiple measurement campaigns …

Chlorinated very short‐lived substances (Cl‐VSLS) are ubiquitous in the troposphere and
can contribute to the stratospheric chlorine budget. In this study, we present measurements …

A new, combined, lidar system has been developed that is able to simultaneously measure
profiles of ozone and water vapor onboard aircraft. The concurrent measurement of these …

The composition of the extratropical transition layer (ExTL), which is the transition zone
between the stratosphere and the troposphere in the midlatitudes, largely depends on …
