Effects of volcanoes in the atmosphere

Effects of volcanoes in the atmosphere

Volcanoes affect atmospheric processes in various ways:

Effects of volcanoes in the atmosphere

While strong explosive eruptions may influence climate for years (The influence of large volcanic eruptions on stratospheric circulation and trace gas concentration), quasi permanent degassing and small eruptions are an important factor for atmospheric chemistry.
