Atmospheric Chemistry and Physics (ACP) is a not-for-profit international scientific journal dedicated to the publication and public discussion of high-quality studies investigating the Earth's atmosphere and the underlying chemical and physical processes. It covers the altitude range from the land and ocean surface up to the turbopause, including the troposphere, stratosphere, and mesosphere.
The main subject areas comprise atmospheric modelling, field measurements, remote sensing, and laboratory studies of gases, aerosols, clouds and precipitation, isotopes, radiation, dynamics, biosphere interactions, and hydrosphere interactions (for details see journal subject areas). The journal scope is focused on studies with important implications for our understanding of the state and behaviour of the atmosphere.
Transparent peer review for 20 years: for 20 years, Atmospheric Chemistry and Physics has been a pioneer in transparent peer review. Submitted preprints, reviews, and author replies are posted and permanently archived on the journal website. This unique approach ensures the highest levels of scientific transparency and integrity, as well as fair peer review for authors.
After 21 years as executive editors of ACP, Uli Pöschl and Thomas Koop have stepped down from day-to-day leadership of the journal and will take up positions on the journal's advisory board. Ken Carslaw and Barbara Ervens will continue as co-chief executive editors. Ken was one of the co-founding editors in 2001, and Barbara joined the executive committee in 2019 following nine years as a regular editor. Read more.

We review the capability of satellite observations of atmospheric methane to quantify methane emissions on all scales. We cover retrieval methods, precision requirements, inverse methods for inferring emissions, source detection thresholds, and observations of system completeness. We show that current instruments already enable quantification of regional and national emissions including contributions from large point sources. Coverage and resolution will increase significantly in coming years.
The Earth's water cycle contains the common H2O molecule but also the less abundant, heavier HDO. We use their different physical properties to study tropical ice clouds in model simulations of the West African monsoon. Isotope signals reveal different processes through which ice clouds form and decay in deep-convective and widespread cirrus. Previously observed variations in upper-tropospheric vapour isotopes are explained by microphysical processes in convective updraughts and downdraughts.

Using the COVID-19 lockdown periods as an example, we show how Sentinel-5P/TROPOMI trace gas data (NO2, SO2, CO, HCHO and CHOCHO) can be used to understand impacts on air quality for regions and cities around the globe. We also provide information for both experienced and inexperienced users about how we created the data using state-of-the-art algorithms, where to get the data, methods taking meteorological and seasonal variability into consideration, and insights for future studies.
Stable water isotopes in marine boundary layer vapour are strongly influenced by the strength of air–sea fluxes. Here, we investigate a distinct vapour isotope signal observed in the warm sector of Southern Ocean cyclones. Single-process air parcel models are used together with high-resolution isotope-enabled simulations with the weather prediction model COSMOiso to improve our understanding of the importance of air–sea fluxes for the moisture cycling in the context of extratropical cyclones.
We quantify global ammonia (NH3) emissions over the period from 2008 to 2018 using an improved fast top-down method that incorporates Infrared Atmospheric
Sounding Interferometer (IASI) satellite observations and GEOS-Chem atmospheric chemical simulations. The top-down analysis finds a global total NH3 emission that is 30 % higher than the bottom-up estimate, largely reconciling a large discrepancy of more than a factor of 2 found in previous top-down studies using the same satellite data.

Short summary
We take advantage of this unexpected low new particle formation frequency in Greece and use a dual atmospheric simulation chamber system with starting point ambient air in an effort to gain insights about the chemical species that is limiting nucleation in this area. A potential nucleation precursor, ammonia, was added in one of the chambers while the other one was used as a reference. The addition of ammonia assisted in new particle formation in almost 50 % of the conducted experiments.

This article investigates the complex precipitation microphysics associated with super typhoon Lekima (2019) using a host of in situ and remote sensing observations, including rain gauge and disdrometer data, and polarimetric radar observations. The impacts of precipitation microphysics on multi-source data consistency and radar precipitation estimation are quantified. It is concluded that the dynamical precipitation microphysical processes must be considered in radar precipitation estimation.

Notice on current restrictions
To show our support for Ukraine and in accordance with current European sanctions, we have introduced a range of measures relevant to our open-access publications process.
All fees for papers from authors (first, corresponding, or contact authors) affiliated to Ukrainian institutions are automatically waived, regardless of if these papers are co-authored by scientists affiliated to Russian and/or Belarusian institutions. The only exception to the waiver for Ukrainian authors will be if the corresponding or contact authors are from a Russian and/or Belarusian institution, in that case the APCs are not waived.
Due to restrictions for authors from Russian and Belarusian institutions that are necessary to comply with European sanctions, we recommend any authors from institutions in these countries to contact us on editorial@copernicus.org for more information.
