Air Quality and Climate Change: Role of Trace Gases
Dr Manish Naja
This is a second part of the talk, covering trace gases in the troposphere and stratosphere. The first part was on some of the basic things. Here, a discussion will be made on the stratospheric ozone and several trace gases in the troposphere. Briefly, observational methods will also be discussed. Both the talks are planned for graduate and postgraduate students.

Air Quality and Climate Change: Introduction
Dr Manish Naja
About the Talk:
This is an introductory talk, discussing some of the basic things related to atmospheric science with more focus on air quality and climate change. Chemical composition of the earth’s atmosphere, greenhouse effect, the role of meteorology and cloud will be discussed. The second part of the talk will cover trace gases in the troposphere and stratosphere. Both these talks are planned for graduate and postgraduate students.
Monitoring the Earth's Atmosphere: Opportunities and Challenges
Dr Narendra Singh
About the Talk:
This talk deals with the basics of atmosphere, its monitoring, research opportunities and challenges. The atmosphere surrounding the earth is a protective gaseous envelope created naturally that sustains the survival of all living beings. This envelope is characterized by various layers within it and having their own importance. Nearly all extreme weather phenomena, global warming and climate change issues take place in the lowermost part of the atmosphere. Observations and precise forecasting of atmospheric phenomena such as extreme rains and floods, thunderstorms, lightning strikes, monsoon, cloud bursts in the Himalayas, etc. are some of the challenges. A brief overview on the atmospheric research facilities at ARIES will also be provided here.
Energetic Explosions in the Universe
Dr Kuntal Misra
About the Talk:
In this talk, she will discuss the end stages and death of stars. This leads to different kinds of explosions releasing a huge amount of energy and resulting in a variety of cosmic sources such as Supernovae and Gamma-Ray Bursts. Such objects are of transient nature and can be short or long-lived. She will give an overview of such energetic cosmic transients and how they serve as useful probes in studying the Universe
