Quantifying the importance of galactic cosmic rays in cloud microphysical processes
TLDR
In this article, five different models developed independently have been coupled to investigate the quantitative effects of charged aerosol-cloud interactions, and the results showed that charging of aerosols increase the scavenging of particles in the size range 0.1 µm to 1 µm.About:

Dynamical evidence for causality between galactic cosmic rays and interannual variation in global temperature
Anastasios A. Tsonis,Ethan R. Deyle,Robert M. May,George Sugihara,Kyle L. Swanson,Joshua D. Verbeten,Geli Wang +6 more
TL;DR: An analysis based on convergent cross mapping uses observational time series data to directly examine the causal link between CR and year-to-year changes in global temperature and finds a significant, although modest, causal effect of CR on short-term, year- to-year variability in GT.

TL;DR: In this paper, the formation rate of 5 nm particles ranged from 3.5 to 13.9 cm(-3) s(-1) and growth rates of both positive and negative ions were greater than those of neutral particles.

Indian summer monsoon rainfall: Dancing with the tunes of the sun
TL;DR: In this article, coupled cloud hydrodynamic equations were used to derive an equation for the rate of precipitation that is similar to the equation of a forced harmonic oscillator, with cloud and rain water mixing ratios as forcing variables.

TL;DR: First results from the CLOUD experiment at CERN are presented, finding that atmospherically relevant ammonia mixing ratios of 100 parts per trillion by volume, or less, increase the nucleation rate of sulphuric acid particles more than 100–1,000-fold and ion-induced binary nucleation of H2SO4–H2O can occur in the mid-troposphere but is negligible in the boundary layer.

TL;DR: In this paper, the development of this review article has evolved from work carried out by an international team of the International Space Science Institute (ISSI), Bern, Switzerland, and from work performed under the auspices of Scientific Committee on Solar Terrestrial Physics (SCOSTEP) regarding climate and weather of the Sun-Earth System (CAWSES).
