== Configuration Description ==
ORCA2_OFF_TRC uses the ORCA2_LIM configuration in which the tracer passive transport module TOP  has been activated in standalone using the dynamical fields that are pre calculated.

See [../ORCA2_LIM3_PISCES here] for general description of ORCA2.

In namelist_top_cfg, different passive tracers can be activated ( cfc11, cfc12, sf6, c14, age ) or my-trc, a user-defined tracer

== Input files ==
 * The dynamical fields are used as input. They are coming from a 2000 years of an ORCA2_LIM climatological run using ERA40 atmospheric forcing: [http://prodn.idris.fr/thredds/catalog/ipsl_public/reee451/NEMO/catalog.html?dataset=DatasetScanipsl_public/reee451/NEMO/INPUTS_DYNA_v3.6.tar INPUTS_DYNA_v3.6.tar] for 3.6 or ORCA2_OFF_v3.7.tar for trunk
