Note that the layers are counted bottom-up. The file Topography/ROMStopoSVIM.nc4 contains the bottom topography (variable 'h') and other spec.s of the model set-up. The file Topography/ROMSlevels.nc4 contains specifications of the vertical position of layer interfaces (variable 'z_interface') and the layer center level (variable 'z_center'), valid if the surface elevation is 0. =========== DESCRIPTION =========== The model experiment was initialized on 1958-01-01. Hence, results provided here also includes the spin-up phase of the model system. Results, particularly for the earliest years, should be treated accordingly. Atmospheric forcing from a regional downscaling of the ECMWF reanalysis was applied. These forcing fields are not publicly available. River fluxes were derived from climatology, but the run-off amplitudes were scaled by the temporal variabilty of the regional precipitation over land, without any delay in the run-off anomalies. Surface salinity was restored towards climatology, with an e-folding time scale of 180 days. Tidal motion was included, but the tidal signal is barely present given the present time resolution (daily, monthly means). Lateral boundary conditions were derived from the Simple Ocean Data Assimilation (SODA) project at the Department of Atmospheric and Oceanic Science, University of Maryland (http://www.atmos.umd.edu/~ocean/). Further, SODA fields for January 1958 served as initial conditions for our model simulations. We are grateful for having this reanalysis available for our use. ======= CONTACT ======= Questions or comments may be sent to arne dot melsom at met dot no Oslo, 2013-02-14 Updated on 2015-05-05
