We report a new method for the simultaneous in situ detection of nitryl chloride
(ClNO2) and dinitrogen pentoxide (N2O5) using chemical
ionization mass spectrometry (CIMS). The technique relies on the formation
and detection of iodide ion-molecule clusters, I(ClNO2)− and
I(N2O5)−. The novel N2O5 detection scheme is
direct. It does not suffer from high and variable chemical interferences,
which are associated with the typical method of nitrate anion detection. We

Monoterpenes play an important role in atmospheric chemistry due to their large anthropogenic and biogenic emission sources and high chemical reactivity. As a consequence, measurements are required to assess how changes in emissions of monoterpenes impact air quality. Accurate and comparable measurements of monoterpenes in indoor and outdoor environments require gaseous primary reference materials (PRMs) that are traceable to the international system of units (SI). PRMs of monoterpenes are ch...

The majority of ground-based aerosols observations are limited to fixed locations, narrowing the knowledge on their spatial variability. In order to overcome this issue, a compact Mobile Aerosol Monitoring System (MAMS) was developed to explore the aerosol vertical and spatial variability. This mobile laboratory is equipped with a micropulse lidar, a sun-photometer and an aerosol spectrometer. It is distinguished by other transportable platforms through its ability to perform on-road measurem...

During several periods since 2005 the Michelson Interferometer for Passive Atmospheric Sounding
(MIPAS) on Envisat has performed observations dedicated to the region of the upper
troposphere/lower stratosphere (UTLS). For the duration of November/December 2005 global
distributions of temperature and several trace gases from MIPAS UTLS-1 mode
measurements have been retrieved using the IMK/IAA (Institut für Meteorologie
und Klimaforschung/Instituto de Astrofísica de Andalucía)

The short-wave infrared (SWIR) spectrometer module of the Tropospheric Monitoring Instrument (TROPOMI), on board the ESA Copernicus Sentinel-5 Precursor satellite, is used to measure atmospheric CO and methane columns. For this, calibrated radiance measurements are needed in which the stray light is reduced strongly. Therefore, a method has been developed and applied in an on-ground calibration campaign to characterize stray light in detail using a monochromatic quasi-point light source. The ...
