TL;DR: The impact of black carbon (BC) aerosols on the global radiation balance is not well constrained as mentioned in this paper, and at least 20% of the present uncertainty in modeled BC direct radiative forcing (RF) is due to diversity in the simulated vertical profile of BC mass.

TL;DR: Ozone is an air quality problem today for much of the world's population as discussed by the authors, and it is estimated that ozone pollution can exceed the ozone air quality standards (AQS) through a combination of local emissions, meteorology favoring pollution episodes and the clean-air baseline levels of ozone upon which pollution builds.

TL;DR: The effects of unified aerosol sources on global aerosol fields simulated by different models are examined in this article, where the authors compare results from two AeroCom experiments, one with different (ExpA) and one with unified emissions, injection heights, and particle sizes at the source (ExpB).
Journal ArticleDOI
Comparing the climate effect of emissions of short- and long-lived climate agents
TL;DR: In this paper, the authors examined the suitability of the time-dependent global temperature change potential (GTP) metric in the context of climate policy and found that the weighting of emissions using the GTP is significantly dependent on the scenarios of future emissions and the sensitivity of the climate system.
Journal ArticleDOI
A global model of the coupled sulfur/oxidant chemistry in the troposphere: The sulfur cycle
TL;DR: In this paper, the year 1996 is chosen as the standard, and a model run with 1996 meteorology and emissions is compared with 1996 observations, and the results agree well with observations overall, although the model tends to overestimate SO2 and underestimate sulfate in Northern Hemisphere winter owing to an oxidation limitation.
