The Indian subcontinent usually stands out when scanning the satellite images and ground-based AERONET observations this time of year. The relatively new IIT Delhi AERONET site reported an extremely high AOD of 2.47 yesterday.

Lewotobi Laki-Laki continues to erupt in Indonesia. So far, observations indicate that very little ash or volcanic gas reached the stratosphere. This means that the volcano's impact on climate will be limited and regional.
