The conversion of sulfur dioxide to sulfuric acid, which condenses rapidly in the stratosphere to form fine sulfate aerosols. A volcanic winter is a reduction in global temperatures caused by droplets of sulfuric acid obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, sulfur-rich, particularly explosive volcanic eruption.
The eruption poured over 17 million tons of the gas into the atmosphere and led to a global temperature decrease of around 0.5 degrees Celsius (0.9 degrees Fahrenheit) that lasted about a year ...
