The analysis

The claim states that Kriging provides the 'optimal' spatiotemporal interpolation for AOD data. While older or hybrid studies successfully employ Kriging as an optimal spatial interpolation tool, a significant body of contemporary literature highlights machine learning, deep learning, and advanced tree-based models (such as ConvLSTM and LightGBM) as superior alternatives for spatiotemporal interpolation and gap-filling. Therefore, the claim is contested rather than universally supported as the current consensus.
