Earth & Space Research

Programs: National aeronautics and space administration (nasa) - -scientific leadership of nasa aquarius ocean salinity satellite: esr provided oversight for mission requirements, concept, development, launch, data processing, analysis, and validation;-production of the nasa surface current database, oscar, with development of the physics through the nasa ocean vector winds science team;-evaluation of mass loss from antarctica's floating ice shelves, and development of new tide models for the arctic ocean and greenland;-scientific studies of el nino dynamics, the ocean mixed layer, and salinity budgets. Ocean observations and analyses for the nasa spurs project. -multi-sensor improved sea-surface temperature (misst) for ioos. Misst project focuses on completing research to improve the quality of the satellite ssts from existing and new sensors, producing multi-sensor blended gap-free ssts from us and international datasets, and successfully broadening the use of these products within specifically targeted coastal applications and the integrated ocean observing system (ioos).

national science foundation (nsf) - - polar studies: relating retreat of greenland's petermann ice shelf to changes in ocean temperature; identifying ocean processes causing accelerated loss of arctic sea ice; ocean and glaciological studies of ross ice shelf, antarctica; -evaluation of effect of ocean eddies on the sea-ice area in the southern ocean;-studies of near inertial oscillations from drifting buoys;-public outreach programs to k-12 students, plus general audiences.

salidrone satellite validation project"using saildrone autonomous in situ data for satellite validation and research into upper ocean physics and ecology" which has been selected for the saildrone ocean data. " ensure the saildrone sst measurement capabilities are improved to the absolute best possible extent. Modeling of the weddell sea with fvcom - akvaplan-niva, tromso, norwaynumerical modeling of the weddell sea, including the ice shelves,using the finite-volume numerical ocean model; conducting, analyzing and documenting numerical simulations of ocean/ice interactions

optimal estimation of sea surface temperature from amsr-e, danish meteorological institute, copenhagen, denmark. The optimal estimation (oe) technique is developed within the european space agency climate change initiative (esa-cci) to retrieve subskin sea surface temperature (sst) from aqua's advanced microwave scanning radiometer--earth observing system (amsr-e). A comprehensive matchup database with drifting buoy observations is used to develop and test the oe setup. It is shown that it is essential to update the first guess atmospheric and oceanic state variables and to perform several iterations to reach an optimal retrieval.
