The Hunga Tonga volcano released a relatively small amount of sulfur dioxide for a cooling effect, with estimates ranging from 0.42 million tonnes to 1.5 million tonnes (0.42 to 1.5 Tg) injected into the stratosphere. While this was much less than previous volcanic eruptions like Mount Pinatubo, it still caused a temporary cooling effect primarily … Read more
Sulfur is in the atmosphere today, primarily as sulfur dioxide (๐๐2) from both natural sources like volcanoes and human activities like burning fossil fuels. While it’s a trace gas on Earth with concentrations around 15 parts per billion (ppb), it’s a major component of other planets’ atmospheres and has significant effects on Earth’s air quality … Read more
Today, the stratosphere is the second-lowest layer of Earth’s atmosphere, extending from about 6 to 31 miles (10 to 50 km) above the surface, and it is characterized by stable, horizontally moving air and the presence of the protective ozone layer. Temperatures increase with altitude in this layer due to the absorption of the sun’s … Read more
Due to the water cycle, the amount of water in the air is constantly changing. The lower troposphere can contain up to 4% water vapor (H2O) in areas near the tropics, while the poles contain only trace amounts of water vapor. The concentration of water vapor decreases drastically with altitude. The upper troposphere has less … Read more
