Climate Change on Titan

Titan's atmosphere has the same principal constituent as the Earth, molecular nitrogen, but with a few percent of methane as the next most abundant molecule. The cloud cover, with a global, high-altitude haze of organic material produced by photosynthesis and patchy, lower-level methane clouds, is reminiscent in structure and total N2 content (if not overall composition), of that of Venus. Methane is the principal greenhouse gas and, allowing also for contributions by the pressure-induced bands...

The Major Role of Clouds and Precipitation in the Earths Energy Budget

Earth Energy Budget Diagram

Clouds play a major role in energizing the climate system they reflect much of the solar radiation back to space and so modulate the global temperature. Nearly half of the remaining radiation that reaches the surface is consumed for evaporation only when the reverse to evaporation occurs, i.e., precipitation, the latent heat in the vapor is released, warms the air and drives the global winds and weather systems. Here we will briefly review the key role of cloud-aerosol-precipitation...

Top panel Schematic representation of the formation and growth of aerosol particles by neutral nucleation of sulfuric acid and water and by ion-induced nucleation via negative ions. Bottom panel Schematic representation of the cumulative change in Gibbs free energy as a function of cluster radius. Nucleation barriers (AG*) and radius of the critical cluster (r*) for the neutral and ion-induced nucleation pathway are indicated. Figure 1. Top panel Schematic representation of the...
