TL;DR: Schellnhuber et al. as mentioned in this paper present Earth System Analysis for Sustainability, a broadest examination of the factors shaping sustainability yet undertaken and makes a significant contribution to our understanding of global systems.

TL;DR: In this paper, the chemistry of ethane and propane was studied using a global two-dimensional 'zonally averaged' height and latitude-dependent tropospheric model, where the authors derived theoretical estimates of the seasonal and latitudinal distributions of a variety of intermediate organic compounds formed by the photochemical oxidation of C2H6 and C3H8.

TL;DR: In this paper, the photochemical box model was used to estimate the aerosol pH as a function of particle size and phase partitioning and thermodynamic properties of HCl, and a new version of the MOCCA model was proposed to simulate multiple aerosol size bins.

TL;DR: In this paper, the effects of stratiform clouds on the evolution and diurnal cycle of halogen species are widespread; they are not restricted to cloud layers, but they are found to be generally more important than H2O2 or O3 in the oxidation of S(IV) in sea salt aerosols in the cloud-free MBL.

TL;DR: In this article, a simple photochemical model has been used to simulate the formation of sulfuric and nitric acid during long-range transport through the atmosphere, which has been shown to have a significant influence on the rate of formation of H 2 SO 4 : a higher emission of NOx tends to reduce the levels of OH and H 2 O 2 close to the source area.
