From the earliest observations of ozone in the lower atmosphere in the 19th century, both
measurement methods and the portion of the globe observed have evolved and changed …

The Tropospheric Ozone Assessment Report (TOAR) is an activity of the International Global
Atmospheric Chemistry Project. This paper is a component of the report, focusing on the …

We show that a fire plume injected into the lower stratosphere at high northern latitudes
during the Canadian wildfire event in August 2017 partly reached the tropics. The transport …

This paper assesses the quality of IASI (Infrared Atmospheric Sounding
Interferometer)/Metop-A (IASI-A) and IASI/Metop-B (IASI-B) ozone (O 3) products (total and …

The characteristics and seasonal variability of the tropical tropospheric distributions of ozone
(O 3) and carbon monoxide (CO) were analysed based on in situ measurements provided …

Three scientific ozone products from the Infrared Atmospheric Sounding Interferometer (IASI)
aboard MetOp-A, retrieved in three different research teams (LA, LATMOS/ULB, LISA) with …

We have analyzed near-global stratospheric data (and mesospheric data as well for H 2 O)
in terms of absolute abundances, variability, and trends for O 3, H 2 O, HCl, N 2 O, and HNO …

The European research infrastructure IAGOS (In-service Aircraft for a Global Observing
System) equips commercial aircraft with a system for measuring atmospheric composition. A …

Using state-of-the-art satellite ozone profile products, and a chemical transport model, we
provide an updated estimate of the tropospheric ozone radiative effect (TO 3 RE) and …

East Asia has experienced rapid development with increasing carbon monoxide (CO)
emission in the past decades. Therefore, uplifting CO from the boundary layer to the free …
