1. MERSEA overall objective is to facilitate the visibility, understanding and exchange of the ocean modelling data, output products for users and evaluate the strengths and weaknesses of the European Capacity for Ocean Monitoring and Forecasting. Marine Environment and Security for the European Area

2. Parameters to be considered Class 1standard products (primary products): 2D and 3D interpolated fields (regular grid) on a standard grid with horizontal resolution: 1/8° for MED and for NAT, and standard depth levels (8 levels for MED, 12 levels for NAT Class 2other model outputs, 2D higher resolution gridded interpolated fields along sections (every 10 km) and 1D tables at point locations Class 3derived quantities computed on a daily basis Class 4derived quantities computed on a weekly basis, useful to assess model performance MERSEA version v4 26 June 2003 Period of interest, July 2003 – July 2004

3. HYCOM and MERSEA  Provide class I and II products for NAT  Provide MED later when we have better vertical  MERSEA compatible NetCDF ready to go Add them to RSMAS LAS server  Problems: No time axis (aggregate via LAS) No SST or SSS (top level at 5m) No SSH in class II

4. 3D daily fields (x, y, z)T,S,U,V (best estimates) 2D daily fields (x, y) of surface boundary fields (quantities as seen by the model)  wind (  x,  y), total net heat fluxes, water flux (E-P-R) 2D daily fields (x, y)SSH, Barotropic STRMF, MLD (  and  ) 3D external fields(on the same grid as the standard model outputs) monthly Levitus and Reynaud climatology (T,S) for NAT monthly MEDatlas climatology (T,S) for MED 2D external fields2D bottom bathymetry (on the same grid as the standard model outputs) Class 1: 2D and 3D interpolated fields MERSEA version v4 26 June 2003
