Short summary
This study presents fused aerosol optical depth (AOD) from a combination of single-view and multi-angle space-borne sensors with ground-based observations across India using Universal Kriging (UK) and a novel hybrid Residual Kriging–Machine Learning (RK-ML) approach. Both methods improve aerosol representation compared to individual datasets. UK-based fused maps highlight the need for better ground coverage, addressed by the RK-ML approach under data-sparse conditions.
