As presented at the recent SEAC4RS Science Meeting (Boulder, Colorado), the newly redesigned JPL Laser Hygrometer (JLH) Mark2 measured enhanced water vapor in the stratosphere due to convective injection over the continental United States. Such convective injections have been suggested to lead to chemical perturbation and ozone depletion in the stratosphere. Enhanced water was measured on five flights of the NASA ER-2 aircraft and observed by Aura MLS (courtesy of Michael Schwartz).
