Datasets > Moana hydrodynamic hindcast version 1.9

Description:

The Moana backbone hindcast version 1.9 dataset is a 25 year hydrodynamic hindcast of New Zealands water generated the Meteorological Service of New Zealand as part of the NZ MBIE funded Moana project. The dataset was generated using the hydrodynamical model ROMS and forced using CFSR atmospheric data and Glorys current data. ![](static/images/uploads/moana_sst.png) The Moana backbone hindcast datasets comes in the form of 4 sources of data stored in 4 subfolders on the thredds server <http://thredds.moanaproject.org:8080/thredds/catalog/moana/ocean/NZB/v1.9/catalog.xml>: **raw_3D**: This folder contains the raw ROMS outputs (3D and 2D fields). All the fields are laid on their original curvilinear grids. Main variables are: * Free-surface height (zeta) in metres * Eastward vertically integrated momentum component (ubar_eastward) in metres per second * Northward vertically integrated momentum component (vbar_eastward) in metres per second * Eastward momentum component (u_eastward) in metres per second * Northward momentum component (v_eastward) in metres per second * Potential temperature (temp) in degrees Celcius * Salinity (salt) _cat*url* = <http://thredds.moanaproject.org:8080/thredds/catalog/moana/ocean/NZB/v1.9/raw_3D/catalog.xml> _base_dods*url* = <http://thredds.moanaproject.org:8080/thredds/dodsC/moana/ocean/NZB/v1.9/raw_3D/> **monthly_avg**: This folder contains monthly averages of the raw ROMS outputs (3D and 2D fields). Main variables are: * Time-averaged free-surface height (zeta) in metres * Time-averaged eastward vertically integrated momentum component (ubar_eastward) in metres per second * Time-averaged northward vertically integrated momentum component (vbar_eastward) in metres per second * Time-averaged eastward momentum component (u_eastward) in metres per second * Time-averaged northward momentum component (v_eastward) in metres per second * Time-averaged potential temperature (temp) in degrees Celcius * Time-averaged salinity (salt) _cat*url* = <http://thredds.moanaproject.org:8080/thredds/catalog/moana/ocean/NZB/v1.9/monthly_avg/catalog.xml> _base_dods*url* = <http://thredds.moanaproject.org:8080/thredds/dodsC/moana/ocean/NZB/v1.9/monthly_avg/> **processed_sfc**: This folder contains 2D variables only (surface, depth-averaged, bathymetry) interpolated to a rectilinear longitude/latitude grid. Main variables are: * Sea surface height above geoid (ssh) in metres * Sea surface temperature (sst) in degrees Celcius * Surface Eastward sea water velocity (us) in metres per second * Surface Northward sea water velocity (vs) in metres per second * Depth-averaged Eastward sea water velocity (um) in metres per second * Depth-averaged Northward sea water velocity (vm) in metres per second * Sea floor depth below mean sea level (dep) in metres _cat*url* = <http://thredds.moanaproject.org:8080/thredds/catalog/moana/ocean/NZB/v1.9/processed_sfc/catalog.xml> _base_dods*url* = <http://thredds.moanaproject.org:8080/thredds/dodsC/moana/ocean/NZB/v1.9/processed_sfc/> **processed_3D**: This folder contains the 3D fields interpolated on a rectilinear longitude/latitude/level 3D grids. Main variables are: * Sea water temperature (temp) in degrees Celcius * Sea water absolute salinity (salt) in 1e-3 * Eastward sea water velocity (u) in metres per second * Northward sea water velocity (v) in meters per second _cat*url* = <http://thredds.moanaproject.org:8080/thredds/catalog/moana/ocean/NZB/v1.9/processed_3D/catalog.xml> _base_dods*url* = <http://thredds.moanaproject.org:8080/thredds/dodsC/moana/ocean/NZB/v1.9/processed_3D/>
