Spatio-Temporal Analysis of No2 Concentration in Binh Duong Province, Vietnam Using Sentinel-5P Imageries and Google Earth Engine

Abstract

This study aims at using Sentinel-5P satellite data for analyzing of NO₂ concentrations in Binh Duong province, Vietnam. Google Earth Engine which is a cloud-based geospatial analysis platform has been used to collect the satellite data and extract information on NO₂ concentrations in Binh Duong in the period from 2018 to 2023. Based on the analysis over time, NO₂ dispersion is dependent on seasonal variation and spatially distribution. The average NO₂ density is ranging from 17.2 to 41.86 µmol/m² in the period from 2018 to 2023. The average NO₂ concentration in the areas with high density of industrial factories is higher than other regions in Binh Duong province. Based on the spatial analysis of NO₂ concentration in Binh Duong, NO₂ index is highest in Di An City and lowest in Phu Giao district. Results from this study is valuable for air pollution monitoring in Binh Duong as well as other industrial provinces in Viet Nam.
