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

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

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

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
