TL;DR: In this article, the authors compare the nitric oxide measurements in the mesosphere and lower thermosphere (60 to 150 km) from four instruments: the Atmospheric Chemistry Experiment-Fourier Transform Spectrometer (ACE-FTS), the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS), the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY), and the Sub-Millimetre Radiometer (SMR).

TL;DR: In this paper, the authors presented a reanalysis of the atmospheric chemical composition from the upper troposphere to the lower mesosphere from August-2004 to December-2017 using the Belgian Assimilation System for Chemical ObsErvations (BASCOE) constrained by the chemical observations from the Microwave Limb Sounder (MLS) on board the Aura satellite.

TL;DR: The first three Canadian Arctic ACE validation campaigns were held during polar sunrise at Eureka, Nunavut, Canada (80° N, 86° W) from 2004 to 2006 in support of validation of the ACE (Atmospheric Chemistry Experiment) satellite mission as discussed by the authors.

TL;DR: In this article, the authors present measurements of a long-range smoke transport event recorded on 20-21 July 2011 over Halifax, Nova Scotia, Canada, during the Quantifying the impact of BOReal forest fires on Tropospheric oxidants over the Atlantic using Aircraft and Satellites (BORTAS-B) campaign.

TL;DR: In this article, the authors compared the performance of four Level-2 MIPAS data processing algorithms using the same Level-1b data provided by ESA, but their retrieval schemes differ, including the choice of microwindows, the regularization approach, the treatment of negative retrieved values, and the cloud detection threshold.
