Abstract Sea‐level rise (SLR) will cause coastal groundwater to in many urban environments. Inundation of contaminated soils by (GWR) alter the physical, biological, and geochemical conditions that influence fate transport existing contaminants. These transformed products can be more toxic and/or mobile under future driven SLR GWR. We reviewed vulnerability sites GWR a US national database case...

One of the methods used to estimate land prices is Geographically Weighted Regression (GWR). The GWR method built based on dependent and independent variables (land prices) (the spatial proximity between object other facilities). However, this study will develop variable by adding a planning zone provide complexity price estimation. This proposes an implementation mechanism setting each type as...

In order to better understand the effects of climate change on ecosystems, the relationship between Normalized Difference Vegetation Index (NDVI) and atmospheric constituents have been explored widely by scientists using the global technique of Ordinary Least Squared (OLS) regression analysis. However, recent studies exploring such relationships at different spatial scales have revealed that lo...

The epidemic of lung cancer in Xuanwei City, China, remains serious despite the reduction of the risk of indoor air pollution through citywide stove improvement. The main objective of this study was to characterize the influences of topography on the spatiotemporal variations of lung cancer mortality in Xuanwei during 1990-2013. Using the spatially empirical Bayes method, the smoothed mortality...

African Americans in the U.S. often live in poverty and segregated urban neighborhoods, many of which have dense industrial facilities resulting in high exposure to harmful air toxics. This study aims to explore the relationship between racial composition and cancer risks from air toxics exposure in Memphis/Shelby County, Tennessee, U.S.A. Air toxics data were obtained from 2005 National Air To...
