Tropospheric halogen chemistry

It should be noted that by adding unknown VOCs and OVOCs deduced from the measurements of OH reactivity in the model calculation, the calculated results of ozone formation tends to shift from the VOC-limited to NOx-limited regime. 

The overall tropospheric halogen chemistry has recently been reviewed by Saiz-Lopez and von Glasow (2012). Also, reviews on heterogeneous reactions on sea salt (Finlayson-Pitts 2003 Rossi 2003) and other specific topics of tropospheric halogen chemistry (Carpenter 2003 Sander et al. 2003 Simpson et al. 2007 von Glasow 2010 Abbatt et al. 2012 Saiz-Lopez et al. 2012) are available.

The reactions of N2O5 with sea salt has attracted interest since they are important as a loss process of N2O5 in the marine boundary layer, and also as a trigger for tropospheric halogen chemistry by forming photochemicaUy active CINO2 in the marine boundary layer in urban coasts. 

In the tropospheric halogen chemistry, CIONO2 is a quasi-stable compound formed in the chain termination reaction of CIO in the urban coastal area where NO concentration is relatively high. The reaction of CIONO2 with sea salt results in photochemically active CI2 as in the process.
