Chemically active climate compounds are either primary compounds like methane (CH4),
removed by oxidation in the atmosphere, or secondary compounds like ozone (O3), sulfate …

Sulfur is an extremely motile and vital element in the Earth's biogeochemical environment,
one whose active redox chemistry maintains small reservoirs in the atmosphere and …

Climate models have continued to be developed and improved since the AR4, and many
models have been extended into Earth System models by including the representation of …

Desert dust aerosols affect Earth's global energy balance through direct interactions with
radiation, and through indirect interactions with clouds and ecosystems. But the magnitudes …

Several recent observational studies have shown organic carbon aerosols to be a significant
source of absorption of solar radiation. The absorbing part of organic aerosols is referred to …

This study presents the results of a broad intercomparison of a total of 15 global aerosol
models within the AeroCom project. Each model is compared to observations related to …

A modal aerosol module (MAM) has been developed for the Community Atmosphere Model
version 5 (CAM5), the atmospheric component of the Community Earth System Model …

This paper evaluates the current status of global modeling of the organic aerosol (OA) in the
troposphere and analyzes the differences between models as well as between models and …

We combine in situ measurements of sea salt aerosols (SS) from open ocean cruises and
ground-based stations together with aerosol optical depth (AOD) observations from MODIS …

We evaluate black carbon (BC) model predictions from the AeroCom model intercomparison
project by considering the diversity among year 2000 model simulations and comparing …
