Spatial distribution characteristics of PM2.5 and PM10 in Xi'an City predicted by land use regression models.
TL;DR: This study is the first to apply land use regression models to the Fenwei Plain, a heavily polluted area in China, and provides a scientific foundation for urban planning, land use regulation, air pollution control, and public health policy making.
Journal ArticleDOI
Urban ventilation of typical residential streets and impact of building form variation
TL;DR: In this paper, the authors investigated the ventilation of residential streets bounded by buildings of different forms and provided suggestions for the design of environmentally sustainable urban streets in residential areas in Nanjing, located in the Yangtze River Delta region in China.
Journal ArticleDOI
An improved pollution forecasting model with meteorological impact using multiple imputation and fine-tuning approach
TL;DR: A deep learning-based Convolutional LSTM-SDAE (CLS) model is presented to forecast the particulate matter level, revealing the correlation between particulates matter and meteorological factors and indicates that the model can improve forecasting accuracy and outperforms the other state of art and baseline models.

Association between exposure to fine particulate matter and obesity in children: A national representative cross-sectional study in China
Qian Guo,Tao Xue,Chunrong Jia,Beibei Wang,Suzhen Cao,Xiuge Zhao,Qian Zhang,Liyun Zhao,Junfeng Jim Zhang,Xiaoli Duan +9 more
TL;DR: Exposure to PM2.5 in the ambient air was significantly associated with childhood obesity, and the findings suggest the need for further research to uncover the roles of PM 2.5 exposure in childhood obesity development.
Journal ArticleDOI
Comparing impact of multi-factor planning layouts in residential areas on summer thermal comfort based on orthogonal design of experiments (ODOE)
TL;DR: Zhang et al. as mentioned in this paper analyzed simulated results based on Physiological Equivalent Temperature (PET) to explain the internal mechanism and found that the layout significance ranking affecting thermal comfort in summer is: buildings, vegetation, pavement.

Air pollution removal by urban trees and shrubs in the United States
TL;DR: A modeling study using hourly meteorological and pollution concentration data from across the coterminous United States demonstrates that urban trees remove large amounts of air pollution that consequently improve urban air quality.
Journal ArticleDOI
Quantifying Spatiotemporal Patterns of Urban Land-use Change in Four Cities of China with Time Series Landscape Metrics
Karen C. Seto,Michail Fragkias +1 more
TL;DR: In this article, the authors provide a dynamic inter-and intra-city analysis of spatial and temporal patterns of urban land-use change, using ten classified Landsat Thematic Mapper images acquired from 1988 to 1999.
Journal ArticleDOI
A global comparative analysis of urban form: Applying spatial metrics and remote sensing
TL;DR: In this article, the authors utilized satellite images of 77 metropolitan areas in Asia, US, Europe, Latin America and Australia to calculate seven spatial metrics that capture five distinct dimensions of urban form.

Almut Arneth,Sandy P. Harrison,Sandy P. Harrison,Sönke Zaehle,Kostas Tsigaridis,Kostas Tsigaridis,Surabi Menon,Patrick J. Bartlein,Johann Feichter,Atte Korhola,Markku Kulmala,D. O'Donnell,Guy Schurgers,Sanna Sorvari,Timo Vesala +14 more
TL;DR: The terrestrial biosphere is a key regulator of atmospheric chemistry and climate, and the overall magnitude of the biogeochemical feedback could potentially be similar to that of feedbacks in the physical climate system, but there are large uncertainties in the magnitude of individual estimates and in accounting for synergies between these effects as mentioned in this paper.

Improving the wind environment in high-density cities by understanding urban morphology and surface roughness: A study in Hong Kong
TL;DR: The study establishes that the simpler two-dimensional ground coverage ratio (GCR), which is readily available in the planning circle, can be used to predict the area's average pedestrian level urban ventilation performance of the city.
