As global air pollution aggravates, it urges us to investigate the evolution of atmospheric related emissions. Recently oxidation flow reactor (OFR) has been widely used to simulate the aging of atmospheric related emissions as its excellent performa

Growing evidence indicates that organic aerosol (OA) is a significant absorber of solar radiation. Such absorptive OA is known as "brown carbon" (BrC). However, a formal analytical method for BrC is currently lacking although several methods have bee

We report the development of a static magnetic field Faraday rotation spectrometer for NO detection. A 5.33 µm continuous-wave quantum cascade laser was used as the probing laser. Line absorption at 1875.81 cm−1 (2Π3/2Q(3/2), υ=1←0) was chosen

Secondary organic aerosol (SOA) can influence the radiative balance of the atmosphere via its optical properties. The single-scattering albedo (SSA) and complex refractive index (RI) are the basic optical parameters of the aerosol particles. Toluene

The n-propyl peroxy radical (n-C3H7O2) is the key intermediate during atmospheric oxidation of propane (C3H8) which plays an important role in the carbon and nitrogen cycles in the troposphere. In this paper, a comprehensive theoretical study on the

The total OH reactivity (kOH′) is an important parameter for quantitative assessment of the atmospheric oxidation capacity. Although laboratory measurement of kOH′ has been achieved 20 years ago, the instruments required are often costly and comp

As an important group of green leaf volatiles (GLVs), C6 hexenyl esters, are found to be widely emitted into the atmosphere by plants and vegetation, especially when they suffer mechanical damage. It is indispensable to understand their atmospheric f
