Description: Das Projekt "The Atmospheric Side of the Freshwater Budget" wird vom Umweltbundesamt gefördert und von Universität Hamburg, Fachbereich Erdsystemwissenschaften, Meteorologisches Institut durchgeführt. The focus of this project is to analyse the observed surface freshwater fluxes through improved estimates of evaporation and precipitation and their individual error characteristics in the HOAPS climatology and its ground validation in climate-related hotspots of the Atlantic Ocean. To enable that in a consistent manner we propose to establish an error characterization of the HOAPS evaporation data by triple collocations with ship and buoy measurements and between individual satellites and to improve the error characterization of the HOAPS precipitation by analysing available shipboard disdrometer data using point to area statistics. After these improvements, an analysis of the spatio-temporal variability of the surface fresh water balance E-P over the Atlantic Ocean is planned, especially with respect to the Hadley circulation and the hotspot regions of interest to related WPs. Also the atmospheric water transport shall be analysed in order to find the source or target region of local fresh water imbalances. And finally, a consistent inter-comparison of the upcoming global ocean surface salinity fields from SMOS with freshwater fluxes from the HOAPS climatology is proposed.
