1.    E- Course on Atmosphere: There were four scientific in this event. The talks were given by Prof. S. L. Jain and summary of these are as below:
Atmospheric structure and composition​ I (on 11th April​ 2018) The atmosphere is a layer of gases surrounding the mother planet Earth that is retained by Earth's gravity. The atmosphere protects life. by absorbing ultraviolet solar radiation, warming the surface by greenhouse effect, and reducing temperature extremes between day and night. In this presentation the details of its composition and structure were discussed.
Atmospheric structure and composition​ II (on 12th April​ 2018) This presentation is in continuation of part I on this topic. Here, the measurements of the minor constituents including greenhouse gases will be discussed. Also, the importance of the Green House Gases (GHG) in the atmosphere and their adverse impact on climate change such as global warming, sea rise etc will be presented.
Atmospheric ozone with special emphasis on “Ozone Hole” (on 13th April​ 2018) OZONE is one of the most important constituents in the atmosphere. Ozone acts as an umbrella and shields the mother planet Earth from the harmful UV radiation.  The anthropogenic activities depleted the ozone globally and developed ozone hole over Polar Regions. Here, present scenario along with measurements of ozone was discussed in detail. 
Studies of the atmosphere using LIDAR (on 14th April​ 2018) LIDAR is a state of art tool to explore atmosphere with very good temporal and spatial resolution. Different types of LIDARS are used for the study of vertical profiles of atmospheric temperature, density, water vapour, ozone, aerosols and many other atmospheric parameters and constituents. In this talk a world of LIDAR and its application for atmospheric exploration was presented and discussed.
