■ Aerosols:---are tiny particles in the air that can be produced when we burn different types of fossil fuels — coal, petroleum, wood and biofuels — in different ways.

• They are suspended in the air. 
• They reduce visibility.

▪ Sea salt, dust, and volcanic ash are are three common types of Aerosol. 

• Natural Sources---
90% Desert dust, volatile organic compounds from vegetation, smoke from forest fires, and volcanic ash are natural sources of aerosols.

■ Anthropogenic Sources---(10%) Fossil fuel combustion produces large amounts of sulfur dioxide, which reacts with water vapor and other gases in the atmosphere to create sulfate aerosols.

• Biomass burning, a common method of clearing land and consuming farm waste, yields smoke that’s comprised mainly of organic carbon and black carbon.

■ Is there a link between aerosols and climate change ? 
• Yes. Aerosols have a profound impact on the climate because, just like greenhouse gases.

• Most aerosols have cooling effect • There is only one aerosol — soot, also known as black carbon — that contribute to global warming.

Indian music:-- Music notes - Raga  ,  also spelled rag or ragam , in the classical music of India, Bangladesh, and Pakistan. It is a melodic framework for improvisation and composition.
