<p class="MsoNormal"><span lang="EN-GB">Stabilized Criegee intermediates (SCI) are highly reactive compounds whose potential role in atmospheric self-cleaning processes has been long discussed. However, experimental evidence for atmospheric reactions of SCI
has only recently been provided, and direct or indirect measurements of SCI in the atmosphere are almost inexistent. An instrument to measure SCI in the atmosphere has recently been developed in the Department of Atmospheric Chemistry of the MPI for Chemistry.
First results indicate a significant contribution of SCI to atmospheric oxidation processes which lead to the removal of pollutants from the atmosphere.

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span lang="EN" style="mso-fareast-language:ES">The Department for Atmospheric Chemistry plans two major measurement campaigns in Asia in 2014 and 2015 to study atmospheric self-cleaning.
A ground-based campaign in India will include measurements of a large set of atmospheric compounds in different seasons, to analyze the mix of anthropogenic as well as biogenic emissions and their evolution with the seasons. Emissions tend to accumulate during
the dry season and are effectively washed out once the Monsoon rains set in. The campaign will aim to study chemical cleansing mechanisms in the pre-Monsoon season as well as clarify the contribution of such processes during the Monsoon season.<o:p></o:p></span></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span lang="EN" style="mso-fareast-language:ES">Since the Monsoon season is characterized by strongly convective systems, i.e. thunderstorms, air is efficiently transported to higher
regions of the troposphere and into the stratosphere. The chemical processing occurring during this upward transport and after its arrival at higher will be studied during an airborne campaign in summer 2015 over the Himalayan region.<o:p></o:p></span></p>
