Multi axis differential optical absorption spectroscopy (MAX-DOAS) of gas and aerosol distributions.
We present and demonstrate a relatively simple algorithm, which converts a set of slant column density measurements of oxygen dimers (O4) and NO2 at several different elevation angles to determine the atmospheric aerosol extinction and the absolute concentration and mixing ratio of NO2 within the atmospheric boundary layer. In addition the height of the atmospheric boundary layer can usually be...
متن کاملRetrieval of Aerosol Profiles using Multi Axis Differential Absorption Spectroscopy (MAX-DOAS)
Multi Axis Differential Absorption Spectroscopy (MAX-DOAS) is a well established measurement technique to derive atmospheric trace gas profiles by collecting scattered light spectra at different elevation angles and subsequent inverse modelling of the radiative transfer (Hönninger et al., 2004). Since aerosol particles are significantly involved in the scattering of the detected light, informat...
متن کاملMulti Axis Differential Optical Absorption Spectroscopy
Multi Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) is a novel measurement technique that represents a significant advance on the well-established zenith scattered sunlight DOAS instruments which are mainly sensitive to stratospheric absorbers. MAX-DOAS utilizes scattered sunlight received from multiple viewing direc-5 tions. The spatial distribution of various trace gases close ...
متن کاملComparison of box-air-mass-factors and radiances for Multiple-Axis Differential Optical Absorption Spectroscopy (MAX-DOAS) geometries calculated from different UV/visible radiative transfer models
The results of a comparison exercise of radiative transfer models (RTM) of various international research groups for Multiple AXis Differential Optical Absorption Spectroscopy (MAX-DOAS) viewing geometry are presented. Besides the assessment of the agreement between the different models, a second focus of the comparison was the systematic investigation of the sensitivity of the MAX-DOAS techniq...
متن کاملSpectral studies of ocean water with space-borne sensor SCIAMACHY using Differential Optical Absorption Spectroscopy (DOAS)
Methods enabling the retrieval of oceanic parameter from the space borne instrumentation Scanning Imaging Absorption Spectrometer for Atmospheric ChartographY (SCIAMACHY) using Differential Optical Absorption Spectroscopy (DOAS) are presented. SCIAMACHY onboard ENVISAT measures back scattered solar radiation at a spectral resolution (0.2 to 1.5 nm). The DOAS method was used for the first time t...
