Satellite Oceanic Observatory Atlas Part II: Near Real Time data The goal of project AOOS - " Atlas Observatoire Océanique Satellites",is to animate of an exchange network for the development of oceanographical satellite data consultation and visualization tools as well as results from models and in- situ measurements, in particular from a Web-based interface. Its aim is to ease the use and integration of remote sensing products in scientific projects and studies. The expected results are: - An exhaustive review of sources of satellite information in oceanography, with an expertise on available products (adequacy, resolution, quality, access, processing); - An easier acces to digital data available from providers, for pre-defined areas, of various bio-geophysics parameters, space-time resolutions, with two level of data : historical (Delayed Time : DT) (see Poster Part1 ) and Near real Time (NRT) ; - A WEB application for data browsing and simultaneous viewing of Quick-Look (QL) images representation and downloading of binary data files. - An access to elaborated ''indices'' resulting from the Units Research teams (for upwelling areas), allowing synthetic representations of space-time environemental dynamics - Development of collaborations with scientific teams, (analysis, modeling, validation,..) and use for developping countries and the promotion of capacity buildings in remote sensing. It is a tool developped by IRD and supported by the ''SPIRALS'' project : Support for Scientific Computing projects for Scientific teams, of IRD/DSI (Delegation des Systèmes d'Information).IRD In the AOOS project frame, from January 2007, we produce daily spatial extraction of «Near Real Time» (i.e. access at day-1/-2) satellite products : Our NRT application provides an operational survey of main oceanic parameters at high spatial and temporal resolution for target areas in developing countries, for the three oceans, mainly for research requirement. From the daily downloaded files from providers, each with its own distributing formats, we develop a uniform access from a “standardized” extraction file and a WEB access for available parameters. This is a attempt to promote remote sensed ocean measurement into operational products data for end-user communities (physics, ecosystem approach, fisheries), where the potential of these information has not been fully reached. Available parameters are level 3 distribution from main operational or scientific agencies and programs : - SST(s) global coverage from Thermal Infra-Red sensor by polar orbiter and geosynchronous platform, but with high cloud cover restrictions. - MSG/SEVIRI : 1/10 deg – 12H synthesis ( Day/Night) - AVHRR/METOP 1/20 deg from EUMETSAT/SAF-OI and MEDSPIRATION projects ( IFREMER/CERSAT distribution); from Micro-wave measurement give an “all weather” information but at low resolution and outside of coastal areas; - TMI/AMSRE ¼ deg daily and 3 days composite from Remote Sensing System (RSS); Recently, level 4 products combine several complementary satellite and in situ together with deliver integrated “merged” SST by optimal interpolation ( GHRSST-PP : 1/10 deg ) - Chlorophyll - and simultaneous SST - from EOS/ACQUA/MODIS (4km) by daily swath or 3 days composites ( “NASA Ocean Color” ); - Wind from ‘Quick Scat” (1/4 deg) NRT 3 days composites and ASCending/Descending daily Orbit ( RSS ).
