Quantifying the Impact of Dust Sources on Urban Physical Growth and Vegetation Status: A Case Study of Saudi Arabia

Recently, dust has created many problems, including negative effects on health, and environmental economic costs, for people who live both near to far from sources of dust. The aim this study is evaluate quantify the impact located inside Saudi Arabia physical growth vegetation status cities. In order do so, satellite data sets, simulated surface data, soil 2000 2021 were used. first step, a map area was generated using multi-criteria decision analysis. Land temperature (LST), cover, moisture, precipitation, air humidity, wind speed, erodibility factors considered as effective criteria in identifying sources. second built-up land maps major cities at different distances years based spectral indicators. Then, spatiaotemporal change extracted. Finally, impacts urban quantified. importance degrees erodibility, LST, precipitation identify 0.22, 0.20, 0.16, 0.15, 0.14, 0.07, 0.05, respectively. Thirteen (with least 8 repetition) identified overlap criteria. had about 300 days with Aerosol Optical Depth (AOD) values greater than 0.85, which indicates that these are active. location nine corresponds previous studies. rates <400 km or >400 source (DMDS) 46.2% 95.4%, reduction average annual normalized difference index (NDVI) sub-regions 0.006 0.002, rate intensity cover sub-region close three times higher farther coefficients determination (R2) between DMDS NDVI 0.52 0.73, respectively, have significant their status.
