Aerosol-Precipitation Interactions over India: Review and Future Perspectives

Table 2

Correlation coefficient between aerosol optical depth (AOD), rainfall, absorbing aerosol index (AAI), cloud effective radius (CER), and cloud optical thickness (COT) over the Arabian Sea, all India, and the Bay of Bengal in July between 2001 and 2010. Correlation coefficient (𝑅²) values ≥0.5 are highlighted in bold.
