-A3 dimensional hydro dynamic model with passive 
constituents (decay, sedimentation), 
- A model describing active constituents (plankton/ 
algae growth and decay, resuspension of sedimented 
matter, etc), 
- A residual current model, 
- The creation of a library of model-reconstructed 
cases, defined by their RS signature. 
Actually we are around half way the final goal. 
The hydrodynamic model is a 3D model, actually 
consisting of a coarse grid (11.445 x 5.723 km) model 
covering the entire Adriatic down to the strait of 
Otranto, and a fine grid (2.861 x 2.861 km) model 
covering solely the Northern Adriatic Sea , north of 
the line Pula-Rimini. The depth is divided in 25 
steps. The fine model derives its sea-boundery 
conditions from the coarse model. 
The initial conditions and the boundary conditions 
of the model runs will be based as far as possible on 
RS data from space, integrated with meteorological 
data and in-situ data. The model is presently 
implemented on the Amdahl mainframe. 
THE ADRIATIC MODEL CALIBRATION CAMPAIGN 
Up to now the JRC modeling effort was essentially by 
contract and and we would be glad to enlarge its 
basis to a concerted action together with several 
institutions or a shared cost action. Furthur on the 
calibration of the actual JRC model is hardly 
possible with RS data and requires extensive in-situ 
measurements, essentially of a type hardly acquired 
up to now (current). 
It is in this context that the JRC tries to organize 
a collaboration to arrive at: 
- a redifinition of the model to make it a common 
objective of more collaborating institutions 
- the organisation of a (or more) massive campaign in 
the Adriatic basin to collect all data needed for 
the calibration of the model and for a better 
understanding of the marine ambience 
The first phase is envisaged to start this fall. 
Workshops are envisaged to investigate the merits 
and drawbacks of the various modeling approaches and 
to arrive at a common modeling concept for the 
Adriatic Sea, supported by several institutions, who 
will engage in further development and 
implementation.
