The study of macroevolution, here defined simply as evolution above the species level, has seen a growing appreciation of the role of physical factors in shaping large-scale evolutionary patterns. Many of the major biotic turnovers, extinctions, and radiations that had once been attributed to direct competitive replacements or adaptive breakthroughs are now seen as physically mediated. Asteroid...

The paper describes the evaluation of organic species concentrations as simulated by an atmospheric chemistry general circulation model. Overall it is a nice paper that deserves publication in ACP although there is a need for more detailed discussions at some places as further discussed in the following. Also in some cases, the rationales for choosing (or omitting) some sensitivity simulations ...

Atmospheric free radicals are low concentration, relatively fast reacting species whose influence is felt throughout the atmosphere. Reactive radicals have a key role in maintaining a balanced atmospheric composition through their central function in controlling the oxidative capacity of the atmosphere. In this tutorial review, the chemistry of three main groups of atmospheric radicals HO(x), N...

Collecting rain for trace elemental analyses can be a difficult task. In Australia, most sampling of atmospheric deposition so far has been concerned with gauging the major element chemistry of atmospheric deposition to the Australian continent. Very little work has been conducted on the trace element chemistry of atmospheric deposition in the Australian landscape and, therefore, collector desi...

This paper presents a summary of a new laser-induced fluorescence instrument for airborne measurements of formaldehyde. As mentioned in the paper, accurate and precise measurements of formaldehyde are needed as they can provide an important constraint to test current models of atmospheric chemistry as well as provide retrieval validation for satellite measurements. The paper provides a detailed...
