Objectives (1)

• Preparation and dissemination of regional
  statistical products like mean, seasonal and
  monthly climatological fields and trends from all
  available historical and recent data collected
  over the North Seas for
• Improving of the data service to a wider range of
  users
• Quality checks of the observation data
• Residual problems in data are detected by
  comparing with the gridded fields values

4
Objectives (2)

• Preparation and dissemination of regional
  statistical products like mean, seasonal and
  monthly climatological fields and trends from all
  available historical and recent data collected
  over the North Seas for
• Check of coherence between climatologies and
  statistics computed in the different regions
• Check the technical performances of the
  SEADATANET system when extracting snapshots of
  quality checked observation data from TAs with a
  forseen 6 monthly period of updating the
  statistics

Description of work (1)

• The products will be specified and validated
  form existing pratices, in cooperation with all
  the regional experts of the countries involved in
  Arctric and North Seas reserach with special
  attention to guidelines and requirements provided
  by ongoing programmes.
• To ensure the best possible quality of these
  data products, all the available in-situ and
  remote sensing data (at the ocean surface) will
  be used for the computations and the results will
  be validated in cooperation with all the regional
  experts.
• In return, feedback will be given on the quality
  of data processed.
• The communication and harmonization aspects with
  other regions will be taken charge of by JRC
  (P20), CLS (P14) and ICES (P19).

Description of work (2)

• JRA8.1 Coordination of the activity including
  recommendations for improving the methodology
  and for operating it in routine mode with
  emphasis on the regional priorities
• JRA8.2 Preparation and dissemination of the
  estimates of the annual seasonal statistics and
  trends on grid points of the sea surface from
  co-located in-situ and satellite data
  transfered by regular snapshots of the
  interconnected transnational in-situ and
  satellite platforms
• Temperature, dynamic height/altimetry, salinity
  (from 2007, when a satellite salinity sensore
  will be available), wind and sea state, sea ice

7
Description of work (3)

• JRA8.3 Preparation and dissemination of the
  best estimates of the annual and seasonal
  statistics and trends on grid points and on the
  whole water coloumn from in-situ observations
• Temperature, salinity, current and biological
  parameters
• JRA8.4 Quality checks and harmonization with
  the other regional data products

8
Milestones

• M11 First test results presented to the Annual
  Workshop
• M23 Regional workshops cross checks of the
  observed data versus gridded data
• coherency checks between different
  regional products
• M35 Results and inter-comparisons to be
  presented at the Annual Workshop
• M47 Results to be presented at the International
  Conference
• M53 Products production on operational mode
