Multi 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 کاملMAX-DOAS measurements in Ny-Ålesund
A new approach to derive tropospheric concentrations of some atmospheric trace gases from ground-based UV/vis measurements is described. The instrument, referred to as the MAX-DOAS, is based on the well-known UV/vis instruments, which use the sunlight scattered in the zenith sky as the light source and the method of Differential 5 Optical Absorption Spectroscopy (DOAS) to derive column amounts ...
متن کاملMulti 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 کاملMAX-DOAS O4 measurements: A new technique to derive information on atmospheric aerosols—Principles and information content
[1] Multi AXis Differential Optical Absorption Spectroscopy (MAX-DOAS) observations of the oxygen dimer O4 which can serve as a new method for the determination of atmospheric aerosol properties are presented. Like established methods, e.g., Sun radiometer and LIDAR measurements, MAX-DOAS O4 observations determine optical properties of aerosol under atmospheric conditions (not dried). However, ...
