A new generation of satellite mission for the estimation of ‘all weather' sea surface temperature. The requirements of the user community for Sea Surface Temperature (SST) are very demanding in terms of accuracy, spatial resolution and revisiting time. A 10km spatial resolution, with an accuracy of 0.3K globally, under clear and cloudy conditions is desired. Infrared observations satisfy these requirements under clear sky, but are hampered by cloud cover. To provide 'all-weather' accurate estimations of the SST at high spatial resolution, satellite missions are being designed, based on passive microwave radiometry, with real aperture or synthetic interferometric antennas. A preliminary analysis of the mission characteristics has been conducted within an ESA study (http://www.microwat.org/) and has provided the main instrument parameters (frequencies, noise, scanning geometry...). Developments are needed to optimize these parameters, to simulate the instrument and to provide a realistic estimate of its performances in terms of SST retrieval. This work involves radiative transfer simulations in the microwave, information content analysis, and development of retrieval methods. Evaluation of the methodology will be tested on existing satellite observations. The work will be performed in close relationship with the engineers involved in the instrument development. Synergy with other satellite observations (essentially from scatterometers and altimeters) will be carefully examined. Applications are invited for a post-doc position on this subject at the Paris Observatory, in collaboration with IFREMER, CMS/ Météo-France, and LOCEAN. Interested candidates are invited to submit a CV and to contact Catherine Prigent (+33 1 40 51 20 18 Catherine.email@example.com <mailto:Catherine.firstname.lastname@example.org>). Deadline: 15 March 2013.
