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.
Journal ArticleDOI
Observations of SO 2 and NO 2 by mobile DOAS in the Guangzhou eastern area during the Asian Games 2010
F. C. Wu,Pinhua Xie,Ang Li,K. L. Chan,K. L. Chan,Andreas Hartl,Yang Wang,Fu Qi Si,Y. Zeng,Min Qin,Jin Xu,Jianguo Liu,Wenqing Liu,Mark Wenig +13 more
TL;DR: In this paper, mobile passive differential optical absorption spectroscopy measurements of SO2 and NO2 were performed in the Guangzhou eastern area (GEA) during the 2010 Asian Games from November 2010 to December 2010.
Journal ArticleDOI
Development of a custom OMI NO 2 data product for evaluating biases in a regional chemistry transport model
Gerrit Kuhlmann,Gerrit Kuhlmann,Yun Fat Lam,H. M. Cheung,Andreas Hartl,Jimmy Chi Hung Fung,Pak Wai Chan,Mark Wenig +7 more
TL;DR: In this paper, the authors presented the custom Hong Kong NO2 retrieval for the Ozone Monitoring Instrument (OMI) on board the Aura satellite which was used to evaluate a high-resolution chemistry transport model (CTM) (3 km × 3 km spatial resolution).
Journal ArticleDOI
NO 2 measurements in Hong Kong using LED based long path differential optical absorption spectroscopy
TL;DR: In this article, the authors presented the first long term measurements of atmospheric nitrogen dioxide (NO2) using a LED based Long Path Differential Optical Absorption Spectroscopy (LP-DOAS) instrument.
Journal ArticleDOI
A novel gridding algorithm to create regional trace gas maps from satellite observations
TL;DR: In this article, a new gridding algorithm was developed to map measurements from the instrument's frame of reference (level 2) onto a longitude-latitude grid (level 3).
