1. JRA6: Black Sea Products

2. Objectives and expected impact: 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 Black Sea for: Improving of the data service to a wider range of users (modellers and non-specialists); Quality checks of the observation data: residual problems in data are detected by comparing with the gridded fields values; 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 foreseen 6 monthly period of updating the statistics.

4. Description of work: JRA6.1: Coordination of the activity including recommendations for improving the methodology and for operating it in routine mode with emphasis on the regional priorities; JRA6.2: Preparation and dissemination of best estimates of the annual and seasonal statistics and trends on grid points of the sea surface from co-located in-situ and satellite data transferred by regular snapshots of the interconnected transnational in-situ and satellite platforms: temperature, dynamic height/altimetry, salinity (from 2007, when a satellite salinity sensor will be available), wind and sea state, sea ice; JRA6.3: Preparation and dissemination of best estimates of the annual and seasonal statistics and trends on grid points and on the whole water column from in-situ observations: temperature, salinity, current and biochemical parameters; JRA6.4: Quality checks and harmonization with the other regional data products.

7. This study will be based on NATO Black Sea Data Base

8. Black Sea Regional Historical Interdisciplinary Database Black Sea inter-disciplinary multivariable historical database was created in the framework of the NATO TU-Black Sea project in 1994-1997. It includes all main physical, chemical and biological variables for the entire Black Sea basin. Database primarily covers the time period from 1963 (and in some cases earlier data sets) with extensive data sets for 1973-1994.
