The cycling of reactive organic carbon (ROC) is central to tropospheric chemistry. We
characterize the global tropospheric ROC budget as simulated with the GEOS‐Chem model. We …

We analyze the 2019 sudden stratospheric warming event that occurred in the Southern
Hemisphere through its impact on the Antarctic ozone. Using temperature, ozone, and nitric acid …

Over the Mediterranean region, elevated tropospheric ozone (O 3 ) values are recorded,
especially in summer. We use the thermal Infrared Atmospheric Sounding Interferometer (IASI) …

The Arabian Peninsula exhibits extreme hot summers and has one of the world's largest
population growths. We use satellite observations and reanalysis as well as climate model …

Precipitation is the largest physical removal pathway of atmospheric reactive organic carbon
in the form of dissolved organic carbon (DOC). We present the first global DOC distribution …

Tropospheric ozone (O 3 ) columns in urban and rural regions as seen by the Infrared
Atmospheric Sounding Interferometer (IASI) are analyzed along with the Global Ozone Monitoring …

Sudden Stratospheric Warming events (SSW) are extreme phenomena during which
stratospheric temperature can increase by tens of degrees in a few days. They are due to the …

Satellite measurements from the thermal Infrared Atmospheric Sounding Interferometer (IASI),
aircraft data from the MOZAIC/IAGOS project, as well as observations from ground-based …

In this paper we investigate a severe pollution episode that occurred in Beijing, Tianjin, and
the Hebei province in January 2013. The episode was caused by the combination of …

This paper presents an extensive intercomparison and validation for the ozone (O 3 ) product
measured by the two Infrared Atmospheric Sounding Interferometers (IASIs) launched on …
