Fine particulate matter (PM2. 5) exposure is a leading mortality risk factor in India and the
surrounding region of South Asia. This study evaluates the contribution of emission sectors …

Atmospheric chemistry models are a central tool to study the impact of chemical constituents
on the environment, vegetation and human health. These models are numerically intense …

As urban areas expand globally, human activities are leading to a sustained increase in non-
methane volatile organic compound (NMVOC) emissions, escalating both environmental …

Due to the rapid development of industrialization and a substantial economy, China has
become one of the global hotspots of nitrogen (N) and sulfur (S) deposition following Europe …

Top‐down estimates using satellite data provide important information on the sources of air
pollutants. We develop a sector‐based 4D‐Var framework based on the GEOS‐Chem …

We present a full-year online global simulation of tropospheric chemistry (158 coupled
species) at cubed-sphere c720 (∼ 12.5× 12.5 km2) resolution in the NASA Goddard Earth …

We describe new publicly available, multi‐year formaldehyde (HCHO) data records from the
Ozone Map** and Profiler Suite (OMPS) nadir mapper (NM) instruments on the Suomi …

As carbon-free fuel, ammonia has been proposed as an alternative fuel to facilitate maritime
decarbonization. Deployment of ammonia-powered ships is proposed as soon as 2024 …

Abstract Model intercomparison studies often report a large spread in simulation results, but
quantifying the causes of these differences is hindered by the fact that several processes …

The nonlinear dependence of the dust saltation process on wind speed poses a challenge
for models of varying resolutions. This challenge is of particular relevance for the next …
