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.
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
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).
Journal ArticleDOI
Investigation of Policy Relevant Background (PRB) Ozone in East Asia
Yun Fat Lam,H. M. Cheung +1 more
TL;DR: In this paper, the influence of Long-range Transport (LRT) of air pollutants from North America and the effect of Stratosphere-Troposphere Transport (STT) on PRB ozone was investigated using GEOS-Chem coupled WRF-CMAQ modeling system.
Posted ContentDOI

Gerrit Kuhlmann,Yun Fat Lam,H. M. Cheung,Andreas Hartl,Jimmy Chi Hung Fung,Pak Wai Chan,Mark Wenig +6 more
TL;DR: In this paper, the authors present a survey of the literature in this area: https://www.referred.org.au/blog/blogging-and-blogging/
