Abstract
Impact of the long duration noontime annular solar eclipse on 15 January 2010 on the vertical distribution of aerosols and mixing layer height (HM) in a well-developed convective atmospheric boundary layer (ABL) has been investigated using continuous Lidar observations over a tropical coastal station, Thumba (8.5°N, 76.9°E). This study shows that HM has decreased from its peak value of ∼1800 m at 12:00 h to ∼1000 m following the annular phase of the eclipse (13:17 h), while the corresponding decrease in the total aerosol abundance of ABL is ∼29%. The post-eclipse increase of HM is rapid compared to that during forenoon.
