This webinar consisted of four talks. The summary of these are as below:

 1. Sun and its variability by Prof. Hari Om Vats (on February 26, 2018) The Sun is the main source of energy in the solar system including our Earth. The Sun has several variations. These can be classified in two categories, namely, quasi regular and irregular. This talk described the structure of Sun and important aspects of its variability as we know them today.

2. Overview of Atmosphere by Prof. Shyam Lal (on February 27, 2018) The Earth is the only planet, known so far, to have a unique atmosphere where life can sustain.  Its distance from the Sun and its atmosphere make its environment warm and inhabitable. This talk highlighted the structure of the atmosphere and important roles of various trace gases.

3. Solar Forcing of Climate and Environment Prof. Som Kumar Sharma (on February 28, 2018) Sun is a perineal source of energy. Solar radiation varies continuously, and it modulates Earth’s climate parameters and environment. Sun-climate connections require continuous observations and modelling to investigate and characterize solar forcing of the Erath’s climate. In this talk impact of solar forcing on climate change were presented in detail.


4. Future challenges of Atmospheric Observations by Prof. Lokesh Kumar Sahu (on March 1, 2018) The Earth's atmosphere is a complex mixture of gases. At present, routine observations are incorporated in weather forecasting and climate models. There has been significant progress in both remote sensing and in-situ observations of various atmospheric parameters. The presentation highlighted the recent progress and challenges in global atmospheric observations.
