Arctic tropospheric ozone: assessment of current knowledge and model performance
As the third most important greenhouse gas (GHG) after CO 2 and methane, tropospheric
ozone (O 3) is also an air pollutant causing damage to human health and ecosystems. This …

A general framework for global retrievals of trace gases from IASI: Application to methanol, formic acid, and PAN
Retrieving concentrations of minor atmospheric trace gases from satellite observations is
challenging due to their weak spectral signature. Here we present a new version of the ANNI …

Using an inverse model to reconcile differences in simulated and observed global ethane concentrations and trends between 2008 and 2014
We use a global model, TOMCAT, and an inverse model, INVICAT, to estimate emissions of
ethane (C2H6) between 2008 and 2014 by assimilating surface flask observations. We find …
