Summary

This study validated the daily Terra-MODIS level 2 combined dark target (DT) and deep blue (DB) aerosol optical depth (AOD) retrievals against ground-based AERONET AOD data in Qena, Egypt, in 2019, to evaluate air pollution and the impact of meteorological variables. The validation showed a high correlation (R=0.7118) between MODIS and AERONET AOD, with improved accuracy through data quality filtering and spatial/temporal collocation. The MODIS AOD tended to overestimate AERONET AOD values in all seasons, potentially due to errors in surface reflectance estimation or aerosol transport from other regions.
