Short summary
We have developed quality-enhanced, gridded datasets for aerosol optical depth (AOD) and absorption AOD by assimilating highly accurate measurements from the dense network of ground-based stations, with respective satellite-retrieved datasets. The assimilated datasets demonstrate improved accuracy and reduced uncertainties as compared to respective satellite products. Thus, these assimilated products emerge as important tools to improve the accuracy of climate impact assessment of aerosols.
