Title A Large-Volume, Coolable Spectroscopic Cell for Aerosol Studies
Abstract A coolable spectroscopic cell for characterising the physical and chemical properties of simulated atmospheric aerosol particles has been constructed. The cell is designed for experiments in which the refractive indices, freezing temperatures, phase and chemical composition of a wide range of aerosol types are measured. The relatively large volume (0.075 m<sup>3</sup>) of the cell reduces wall-aerosol interactions and allows the aerosol residence time to exceed 2 hours. The cell has been optically interfaced to Fourier transform spectrometers for recording broadband infrared, visible, and ultraviolet extinction spectra of aerosol particles and gas-phase components over a range of temperatures (180 - 300 K). The data generated using the cell have applications in remote sensing, radiative transfer models, heterogeneous atmospheric chemistry, and pollution studies.
