| description | <p>This study describes the design of the Manchester Aerosol Chamber (MAC), initially developed in 2005 and presents for the first time its comprehensive characterisation. The MAC is designed to investigate multi-phase chemistry and the evolution of aerosol physico-chemical properties from the real-world emissions (e.g. diesel engine, plants) or of secondary organic aerosol (SOA) produced from pure volatile organic compounds (VOCs). Additionally, the generated aerosol particles in the MAC can be transferred to the Manchester Ice Cloud Chamber (MICC), which enables investigation of cloud formation in warm, mixed-phase, and fully glaciated conditions (with temperature, <span class="inline-formula"><i>T</i></span>, as low as <span class="inline-formula">−55</span> <span class="inline-formula"><sup>∘</sup>C</span>). The MAC is an 18 <span class="inline-formula">m<sup>3</sup></span> fluorinated ethylene propylene (FEP) Teflon chamber with the potential to conduct experiments at controlled temperature (15–35 <span class="inline-formula"><sup>∘</sup>C</span>) and relative humidity (RH; 25 %–80 %) under simulated solar radiation or dark conditions. Detailed characterisations were conducted at common experimental conditions (25 <span class="inline-formula"><sup>∘</sup>C</span>, 50 % RH) for actinometry and determination of background contamination, wall losses of gases (<span class="inline-formula">NO<sub>2</sub></span>, <span class="inline-formula">O<sub>3</sub></span>, and selected VOCs), aerosol particles at different sizes, chamber wall reactivity, and aerosol formation. In addition, the influences of chamber contamination on the wall loss rate of gases and particles and the photolysis of <span class="inline-formula">NO<sub>2</sub></span> were estimated.</p> |
