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.
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
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.
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
India's Participation to Thirty Meter Telescope Project
The Thirty Meter Telescope (TMT) is one of the extremely large telescopes that will allow us to see deeper into space and observe cosmic objects with unprecedented sensitivity. The TMT will have three times bigger aperture than the currently existing largest visible-light telescopes in the world. The new cutting-edge technology and adaptive optics technique enable TMT to provide unparalleled spatial resolution with images more than 12 times sharper than those from the Hubble Space Telescope. It will provide new observational opportunities in the field of astronomy and astrophysics with various instruments from ultraviolet to mid-infrared. This unique facility will allow astronomers to address fundamental questions in astronomy ranging from understanding planets and star formation to unravelling the history of galaxies and large-scale structure in the Universe. In this presentation, I also briefly touch upon India's contribution towards this mega-project as a 10% partner.
