AB: The MLS instrument on board the Aura satellite launched on 15 July 2004 is providing daily near global upper tropospheric humidity and cloud ice profile data. MLS has observed one annual cycle of humidity and cloud ice in the tropical upper troposphere and lower stratosphere (UTLS). The new Aura MLS measurements are compared to UARS HALOE and UARS MLS humidity measurements and to a model that incorporates resolved cloud physics and parameterized convection. Model and observations are applied to determining the relative importance of convective and in situ processes in regulating the annual cycles of humidity and cloud ice in the tropical UTLS.
