Cloud detection and classification based on MAX-DOAS observations [PDF]
Atmospheric Measurement Techniques, 2014 Multi-axis differential optical absorption spectroscopy (MAX-DOAS) observations of aerosols and trace gases can be strongly influenced by clouds. Thus, it is important to identify clouds and characterise their properties. In this study we investigate the

Enhancing MAX-DOAS atmospheric remote sensing by multispectral polarimetry [PDF]
, 2021 Multi-AXis Differential Optical Absorption Spectroscopy (MAX-DOAS) is a well-established remote sensing technique for the detection of atmospheric aerosol and trace gases. Ultra-violet and visible radiation spectra of skylight are analysed to obtain information on different atmospheric parameters.

Estimation of NOx emissions from Delhi using Car MAX-DOAS observations and comparison with OMI satellite data [PDF]
Atmospheric Chemistry and Physics, 2011 We present the first Multi-Axis-(MAX-) DOAS observations in India performed during April 2010 and January 2011 in Delhi and nearby regions. The MAX-DOAS instrument was mounted on a car roof, which allowed us to perform measurements along individual ...

MAX-DOAS detection of glyoxal during ICARTT 2004 [PDF]
Atmospheric Chemistry and Physics, 2006 Abstract. The direct detection of glyoxal (CHOCHO), the smallest α-dicarbonyl, in the open atmosphere by active differential optical absorption spectroscopy (DOAS) has recently been demonstrated (Volkamer et al., 2005a) and triggered the very recent successful detection of CHOCHO from space (Kurosu et al., 2005; Wittrock et al., 2006; Beirle et al ...
