DOI: 10.1002/2017jd026482
Abstract: Transport in the tropical lower stratosphere plays a major role in determining the composition of the entire stratosphere. Previous studies that quantified the relative role of transport processes have generally assumed âĂIJwell mixedâĂI tropics and… read more here.

DOI: 10.1002/qj.3801
Abstract: Stratospheric water vapour (SWV), in spite of its low concentration in the stratosphere as compared to the troposphere, contributes significantly to the surface energy budget and can have an influence on the surface climate. This… read more here.
