AATSR & SLSTR

AATSR Processor Update AATSR operational processor will be updated later this year –Current estimate is mid-September 2010 Will provide updates to –Alignment of forward and nadir views –Visible channel calibration –SST retrieval coefficients New SSES will be provided in updated L2P

L2P NRT Processing NRT Operational from 1 st December 2008 Performance excellent when NRT data available See graph Improved performance downloading files from Rolling Archive No AOD or SST Analysis in the product. Still using ECMWF data via BADC and not direct link.

L2P NRT Performance May Acquisition to L2P generation.

L2P Offline Processing ATSR-1, ATSR-2 provided by NEODC. Aligned ESA with NEODC AATSR. All data to 31/12/2008 provided by NEODC AATSR and 2010 data responsibility of ESA to generate at UK-MM-PAF 2009 and 2010 completed at UK-MM-PAF. No gaps. Nominal Offline L2 Processing switched on. All L2P on FTP server. LTO to be distributed to Cat1 users (LTSRF - Ken Casey). Announcement to be made on Earthnet web page.

ERS Envisat 2006 ERS Envisat operations should end in 2010, but Member States have agreed to fund a 3-year extension Envisat mission extension 1 st Tandem 2 nd Tandem ERS SAR Tandem 3 rd Tandem New orbital parameters The Envisat 3-years extension requests a modification of the orbital parameters in 2010 to be able to operate the satellite with minimum hydrazine.  Envisat satellite is in good health and with an expected reasonable evolution.  Efficient consumption of on-board hydrazine allows operating nominally Envisat until 2010 (nominal lifetime ended in Feb. 2007). But most of hydrazine will be consumed by 2010.

Envisat Envisat mission extension The new orbital parameters allow: 1.to keep current nominal mission until October 2010, 2.to extend the mission until end 2013, 3.to allow operations of all instruments with small or no degradation of their measurements, and minor impact on data quality, excepted for SAR interferometry 4.to commit with the satellite disposal rules. End-October 2010: Altitude change: km Repeat cycle: 30 days / 431 orbits Orbit control: altitude control with inclination drift Mean Local Solar Time variation: +/- 10 min. Detailed information will be provided during ESA Living Planet Symposium (28 June 2010)

Sentinel–3 Overview The Sentinel 3 Mission is part of the Global Monitoring for Environment and Security (GMES) initiative Sentinel- 3 is an operational mission in high-inclination, low earth orbit Full performance achieved with 2 satellites in orbit Sentinel-3 implements 3 core missions to deliver continuity to existing ones: Sea and land colour data, at least at the level of quality of the Medium Resolution Imaging Spectrometer (MERIS) instrument Sea and Land surface temperature, at least at the level of quality of the Advanced Along-Track Scanning Radiometer (AATSR) instrument Sea surface topography data at least at the level of quality of the Envisat Radar Altimeter (RA) system In addition, the optical payload design will allow data continuity of the Vegetation instrument (on SPOT4/5), enhanced fire monitoring capabilities.

Sentinel-3 Instrument swath overlay Ground track spacing (with 1 Satellite) after 1 day = 2810 km 3 days = 1450 km 4 days = 750 km 27 days = 104 km SLSTR Nadir swath is ~1375 km Inclined swath is ~700 km See presentation of Craig Donlon on Thursday (16:40)

Medspiration 2

 New objectives Continue to deliver quality and improved products Support and enable development of advanced services based on SST  Deliver routinely data or information tailored to reach large audience, e.g. TV channels or internet Support specific user needs  Implement and deliver routinely on-demand custom products for specific scientific projects or applications, e.g. ESA/BioDiversity (Galapagos/Coco Islands), SMOS (Amazon basin and Tropical Atlantic),...

Products  L4 :Ultra-high resolution (2km), daily, gap free, multi-sensor merged maps of SST in support to projects Mediterranean Sea Complete time series will be produced over the full Medspiration era ( ) Amazon basin In support to SMOS salinity mission North-East Australia In support to Great Barrier Reef monitoring South-Africa In support to dynamic characterization from multiple sensor (SAR, SST, Ocean color)

Media and public outreach

Odyssea processing chain  Major improvements have been undertaken in the last year in order to deliver a sustained quality product, cope with lack of data, cross sensor intercalibration, interpolation, regional properties  Processing chain now being integrated and tested in operational environment  These products will be available routinely starting from September 2010 (24h delay after satellite acquisition)  Main changes :  Taking into account history : Odyssea uses the previous analysis (or Climatology after several days without any data) as background and updates with data increments  daily intercalibration by estimating daily large scale bias fields (~synoptic weather scales) for each single source. New reference = daily global large scale SST field constructed with observations from all the sources (to avoid relying on a single sensor, even if very good quality like AATSR, and ensure continuous and sustained quality)  Regional properties for interpolation local correlation scales estimated at each grid point variograms estimated locally, taking into account regional differences and anisotropy

-Assimilation? -Validation? MFCs needs?

MyOcean SST validation Quality control (QC) activities produce flags in Real time :green yellow red Validation activities are performed in delayed mode and aim to provide detailed information on the accuracy of the products. Both inputs (L2P) and outputs (L3) to the production centre are subject to QC and validation For QC and validation the reference datasets are SST climatology, drifting buoy measurements and the AATSR derived SST fields All Myocean SST products will be validated against AATSR L3C
