TL;DR: In this paper, the first results of the measurements of trace gases and aerosols at three surface sites in and outside Beijing before and during the 2008 Olympics were presented, which indicated the success of the government's efforts in reducing emissions of SO2, CO, and VOCs in Beijing, but increased regional emissions during 2005-2008.
Journal ArticleDOI
Impact of Urbanization on Meteorology and Air Quality in Chengdu, a Basin City of Southwestern China
TL;DR: In this paper , the authors analyzed the changes of meteorological phenomenon and evolution of air pollutants induced by urbanization and found that the urban expansion area (i.e., land use transition from natural to urban surfaces between 2000 and 2017, UEA) has a significant increase in nocturnal 2m temperature with maximum values reaching 3 and 4°C in summer and winter, respectively.

Journal ArticleDOI
Identification of a wetland ecological network for urban heat island effect mitigation in Changchun, China
TL;DR: Wang et al. as discussed by the authors used morphological spatial pattern analysis and landscape connectivity index combined with the wetland cooling index to identify ecological sources with high cooling capacity, and an ecological resistance surface was constructed with surface temperature as the main factor.
Journal ArticleDOI
Impacts of land use and land cover changes on local meteorology and PM2.5 concentrations in Changchun, Northeast China
TL;DR: Based on the WRF-CMAQ model, the LULC2017 and LULC2001 (LULC data in 2001) scenarios were simulated for January and July 2017, respectively, to assess the impact of LULC changes on meteorology and fine particulate matter (PM2.5) concentrations in Changchun as discussed by the authors .
