In this study we investigate the quality of the selection process of an open access (OA) journal, taking as an example the journal Atmospheric Chemistry and Physics (ACP). ACP is working with a new system of public peer review. We examined the predictive validity of the ACP peer review system – namely, whether the process selects the best of the manuscripts submitted. We have data for 1111 manu...

Nitrous acid (HONO) is of particular importance in atmospheric chemistry; its photolysis significantly enhances photooxidation processes early in the morning or during wintertime, through the rapid production of OH radicals in the presence of long wavelength radiation, and in urban areas with low O3 levels. Previous studies reveal that neither direct HONO emissions from combustion sources nor h...

A number of key problems in atmospheric chemistry are shaped by the strength and character of the various mechanisms acting to move and mix air in the upper troposphere. These transport processes are examined from a mechanistic perspective, with primary emphasis on the tropopause andmiddle-troposphere regions in the extratropics. The roles of vertical and horizontal transport “barriers” are exp...
