Short summary
A long-term record of satellite observations is used to study extreme water vapor concentrations in the lower stratosphere, which are important to climate variability and change. We use a deeper layer of stratospheric observations than prior work to more comprehensively identify these events. We show that extreme water vapor concentrations are frequent, especially in the lowest layers of the stratosphere that have not been analyzed previously.
