The POM (Princeton Ocean Model)
coastal water quality model

For details of the model operation, assumption, coefficients etc., please consult the POM description on the ECOSIM web pages.

In the Athens Demonstrator, POM is implemented with the following features and constraints:

• the model is implemented for a domain of 100 by 100 kilometers with a 2 km grid (50 by 50 cells of 2 by 2 km);

• dwimeteorological and oceanographical conditions are limited to a set of predefined monthly scenarios;

• the model runs are limited to a set of predefined length, ranging from 1 to 28 days;

• only a conservative tracer is suported;

• there is an option to relocate sources, but they have to be predefined in TEMPLATES (or scenario examples) since the interface does NOT allow to add a new source.

Please note that all static input data that are NOT edited by the POM interface, see below, are provided at the server side; this includes initial and boundary conditions of the model, and any dynamic forcing applied.

POM can be implemented as a remote server or as a local executable, with the same client-server protocol, which requires the installation of a local www server (httpd), see: ECOSIM Installation Guide.

The corresponding server URL is specified in the default file ./defaults/neco in the Athens Demonstrator version:

*.cliser.sernames.n:          3
*.cliser.sernames.name.1:     Athens MEMO
*.cliser.sernames.node.1:     aix.meng.auth.gr/cgi-bin/memo
*.cliser.sernames.name.2:     MP1 POM
*.cliser.sernames.node.2:     mp1:8080/cgi-bin/sarpom
*.cliser.sernames.name.3:     Athens GW
*.cliser.sernames.node.3:     aix.meng.auth.gr/cgi-bin/mt3d

To modify the list of servers and potential alternates and backups, modeify the node name in the deafult file; when adding a server, please make sure to also update *.cliser.sernames.n accordingly.

POM functionality

• editing and submitting new simulation requests;
• display and analysis of a simulation scenario result (same as for REGOZON).
