TL;DR: In this paper, a new inversion algorithm (PriAM) is implemented to retrieve profiles of the trace gases and aerosol extinction from the UV spectra of scattered sunlight recorded by the MAX-DOAS instrument.
Journal ArticleDOI
Validation of OMI, GOME-2A and GOME-2B tropospheric NO 2 , SO 2 and HCHO products using MAX-DOAS observations from 2011 to 2014 in Wuxi, China: investigation of the effects of priori profiles and aerosols on the satellite products

TL;DR: In this article, a comparison between satellite and MAX-DOAS VCDs is performed using a sensitivity study using different spatial and temporal averaging conditions, and the results indicate that the discrepancies between satellite VCD results increase with increasing effective cloud fraction and are dominated by the effects of clouds on the satellite products.
Journal ArticleDOI
Observations of tropospheric NO2 using ground based MAX-DOAS and OMI measurements during the Shanghai World Expo 2010

TL;DR: In this paper, the authors measured NO2 using four identical MAX-DOAS instruments in Shanghai from April 2009 to November 2010 and found that the overall NO2 reduction was mainly achieved by emission control policies on transportation sources in the city rather than the controls from nearby provinces.

TL;DR: In this paper, a latitudinal cross-section and vertical profiles of iodine monoxide (IO) were reported from the marine boundary layer of the Western Pacific using multi-axis differential optical absorption spectroscopy (MAX-DOAS) during the TransBrom cruise of the German research vessel Sonne, which led from Tomakomai, Japan (42° N, 141° E) through the western Pacific to Townsville, Australia (19° S, 146° E).
Journal ArticleDOI
Parameterizing the instrumental spectral response function and its changes by a super-Gaussian and its derivatives
TL;DR: In this paper, a super-Gaussian is proposed to describe the ISRF of various DOAS instruments, including the satellite instruments GOME-2, OMI, and TROPOMI.
