Description
Summary:From January 2016 until August 2018, an automated Long-Path Differential Optical Absorption Spectroscopy (LP-DOAS) instrument was operated at the German research station Neumayer III (NMIII) in coastal Antarctica to measure trace gas mixing ratios in the boundary layer close to the ground (average altitude above the snow surface: 4m). Two different atmospheric light paths with total lengths of 3100 m and 5900m were used depending on visibility.The DOAS evaluation of NO2 was performed between 352.5 and 386.5 nm as well as in a second spectral window (for subsequent measurements in two different instrumental setups). Here a fit between 424.3 and 451.3 nm was used for data until February 15th, 2017 when another grating was used. After February 15th, 2017, the evaluation was performed between 411 and 438 m. Fits with residual optical density RMS (root mean square) values larger than 3.5e-4 and 5.0e-4 (later 2.8e-4) respectively were discarded. The resulting mean residual RMS are 2.2e-4 and 3.2e-4 (1.8e-4 later) ...
