AB: HALOE, POAM, ATMOS, and SAGE have all reported measurements of H2O (and in several cases, H2O isotopologues) from orbit by solar occultation. I will discuss recent measurements pertaining to trends in stratospheric and upper tropospheric H2O as well as describe the use of isotopic analysis to constrain the mechanisms that control the humidity of this region of the atmosphere.
