CONCURRENT LINKING OF SMOS SOIL MOISTURE AND SEA SURFACE SALINITY PRODUCTS TO THE GLOBAL WATER CYCLE

摘要

The potential of the SMOS salinity (SSS) and surfacernsoil moisture (SSM) datasets to contribute torncharacterise the vertical water mass exchange at therninterface between the atmospheric and the terrestrialrn(including land and ocean) water reservoirs wasrnanalysed using state-of-the-art satellite-basedrnacquisitions of E and P. The geographical patterns ofrnthe medians of SSS and I = E – P closely corresponded.rnThe SSS and I analyses over time depicted distinctivernregions of high correlation along the Inter-TropicalrnConvergence Zone (ITCZ) zone. Over land, significantrncorrelations between SSM and I were found over timernover the transitional zones between wet and dryrnclimates. These findings agree with the prior studies ofrnmodelled I, SSS and SSM and therefore advocate thernrole of the SMOS observations of SSS and SSM in thernglobal water cycle studies.
