eReefs AIMS-CSIRO Aggregations of hydrodynamic model outputs

This generated data set contains summaries (daily, monthly, annual) of the eReefs CSIRO hydrodynamic model v2.0 ( outputs at both 1km and 4km resolution, generated by the AIMS eReefs Platform ( These summaries are derived from the original hourly model outputs available via the National Computing Infrastructure (NCI) (, and have been re-gridded from the original curvilinear grid used by the eReefs model into a regular grid so that the data files can be easily loaded into standard GIS software. These summaries are updated in near-real time (daily) and are made available via a THREDDS server (http://thredds.ereefs.aims.g...alog.html) in NetCDF format. For more information about the eReefs hydrodynamic modelling see Method: A description of the processing, especially aggregation and regridding, is available in the "Technical Guide to Derived Products from CSIRO eReefs Models" document ( Data Dictionary: The following variables are available: - eta: Surface elevation (sea surface height above sea level) (metres) - salt: Salinity (PSU) - temp: Temperature (degrees C) - wspeed_u: Eastward wind (ms-1) - wspeed_v: Northward wind (ms-1) - u: Eastward sea water velocity (second half of the current vector) (ms-1) - v: Northward sea water velocity (half of the current vector) (ms-1) - mean_wspeed: Mean Wind speed magnitude (ms-1) - mean_cur: Mean sea water velocity (current) magnitude (ms-1) Depths: This data set contains a subset of the depths available in the source data sets, which differ slightly between the 1km and 4km models. Depths at 1km resolution: -0.5, -2.35, -5.35, -9.0, -13.0, -18.0, -24.0, -31.0, -39.5, -49.0, -60.0, -73.0, -88.0, -103.0, -120.0, -140.0, Depths are 4km resolution:-0.5, -1.5, -3.0, -5.55, -8.8, -12.75, -17.75, -23.75, -31.0, -39.5, -49.0, -60.0, -73.0, -88.0, -103.0, -120.0, -145.0. Limitations: The wind data is originally from the BOM Access-R weather models. These models capture synoptic winds and some of the features of cyclones, however they do not represent the high speed winds near the eye of cyclones well. For this reason the maximum wind speed aggregations do not capture the peak winds of cyclones. The GBR1 yearly summaries of salinity and temperature have a known problem where the data is WRONG with a sharp boundary appearing at edge of the GBR. Do not use this data. We will investigate and resolve the issue with this data. This dataset is based on a spatial and temporal model and as such is an estimate of the environmental conditions. It is not based on in-water measurements, and thus will have a spatially varying level of error in the modelled values. It is important to consider if the model results are fit for the intended purpose.
