- Abstract:
- The proposal is to construct a broadband cavity ringdown spectrometer for measurements of atmospheric NO3 and N2O5, and for laboratory studies of the H20 continuum. Measurements of NO3 are generally made using long path absorption methods. In most urban conditions structure is expected to be present on smaller spatial scales, with night time chemistry active at plume boundaries. The proposed instrument will allow detailed investigation of this effect, including characterisation of its oxidant potential. A two channel instrument is proposed, to measure both NO3 and N2O5. The H2O continuum absorption is poorly understood in the near IR and visible. Broadband CRDS will allow the simultaneous determination of H2O monomer concentrations and any continuum absorption. A series of studies are proposed, using a dedicated temperature and pressure controlled sample cell.
