Abstract. Trace gases play a key role in the chemistry of urban atmospheres. Therefore, knowledge about their spatial distribution is needed to fully characterize the air quality in urban areas. Using a new Multi-AXis Differential Optical Absorption Spectroscopy (MAXDOAS)-2D instrument, along with inversion algorithms, we report for the first time two-dimensional maps of NO2 concentrations in the city of Madrid, Spain. We found good agreement between the MAXDOAS-2D mesoscale observations and the in-situ measurements provided by Madrid´s air quality monitoring stations. In addition to vertical profiles, we studied the horizontal gradients of NO2 in the surface layer by applying the different horizontal light path lengths in the two spectral regions included in the NO2 spectral analysis: ultraviolet (UV, at 360 nm) and visible (VIS, 477 nm). Finally, we also investigate the sensitivity of the instrument to infer vertically-distributed information on aerosol extinction coefficients and discuss possible future ways to improve the retrievals.
