Retrieval of profile information from airborne multiaxis UV-visible skylight absorption measurements

NO2 Profile retrieval using airborne multi axis UV-visible skylight absorption measurements over central Europe

A recent development in ground-based remote sensing of atmospheric constituents by UV/visible absorption measurements of scattered light is the simultaneous use of several directions with small elevation angles in addition to the traditional zenith-sky pointing. The different light paths through the atmosphere enable the vertical distribution of some atmospheric absorbers such as NO2, BrO or O3...

Resin bead micro-UV-visible absorption spectroscopy.

The construction and design of a microscope coupled with a miniature UV-vis spectrometer is described. This was applied to the study of dyes linked to solid supports and displayed good correlation in spectral shape and lambda(max) values when compared to the dyes in solution, as well as showing a linear relationship between dye loading and UV-vis absorbance. The spectral profiles of these dyes ...

The UV-visible absorption cross-sections of IONO2

The UV-visible absorption spectrum of gaseous IONO2 has been measured over the wavelength range 245– 415 nm using the technique of laser photolysis with timeresolved UV-visible absorption spectroscopy. IONO2 was produced in situ in the gas phase by laser flash photolysis of NO2/CF3I/N2 mixtures. Post flash spectra were deconvolved to remove contributions to the observed absorption from other re...
