Sentinel-1 SAR medium resolution (approximately 20m-pixel size) reprojected and calibrated product produced by CSIRO under eReefs Phase 5 using the SNAP (Sentinel Application Platform) toolbox. This product was derived from Level 1 IW GRD (VV polarization), placed onto a regular grid using nearest neighbor resampling and radiometrically filtered using a three-pass combination of filters to reduce speckle.
-
Sentinel-3 OLCI full resolution (approximately 300m-pixel size) daily reprojected Level 2P water quality (Chl-a, CDOM, TSS) produced by CSIRO under eReefs Phase 5 using the FUB-CSIRO Coastal Water Processor (detailed description at https://doi.org/10.1016/j.rse.2021.112848). This product was derived from Level 2 geophysical quantities, and placed onto a regular grid using nearest neighbor resampling. Standard Level 1 quality flags have been applied to pre-mask and quality control the data (see file_version_quality_control). Additional algorithm input and output out-of-range flags (in_out_OR_combined_flags) are provided to further quality control the data. These flags have not been applied to pre-mask the data.

Sentinel-3 OLCI reduced resolution (approximately 1000m-pixel size) daily Level 1B true-colour quicklooks produced by CSIRO under eReefs Phase 5 delivered in GeoTIFF format.

Sentinel-3 OLCI reduced resolution (approximately 1000m-pixel size) daily reprojected Level 2P above-water spectral remote sensing reflectance produced by CSIRO under eReefs Phase 5 using the FUB-CSIRO Coastal Water Processor (detailed description at https://doi.org/10.1016/j.rse.2021.112848). This product was derived from Level 2 geophysical quantities, and placed onto a regular grid using nearest neighbor resampling. Standard Level 1 quality flags have been applied to pre-mask and quality control the data (see file_version_quality_control). Additional algorithm input and output out-of-range flags (in_out_OR_combined_flags) are provided to further quality control the data. These flags have not been applied to pre-mask the data.

**This sample dataset was decomissioned in May 2022, and is no longer available via the NCI THREDDS server. Please contact the eReefs team if you need access to this data.** This is the eReefs GBR 4 km resolution Data Assimilating (DA) hydrodynamic SHOC model data. The Ensemble Optimal Interpolation (EnOI) system assimilaties a combination of temperature data from moorings (AIMS and GBROOS/IMOS), gliders (CSIRO and IMOS) and SST (GHRSST L3S from IMOS). This product is the first version of a reanalysis undertaken for the GBR4 grid. The DS system is run with a cycle length of 2 days, and assimilates temperature data that fall within a 6 hour window either side of the analysis time. The mean forecast error ranges from 0.4 degrees C in the "dry" season to 0.7 degrees C in the "wet" season

**This sample dataset was decomissioned in May 2022, and is no longer available via the NCI THREDDS server. Please contact the eReefs team if you need access to this data.** This is the eReefs GBR 4 km resolution complete hydrodynamic Sparse Hydrodynamic Ocean Code (SHOC) model data v1.85. It is comprised of ALL the tracers that are present in the SHOC model. The output format is non-CF compliant as it is a "standard" SHOC ALL file. It is based on the Arakawa-C grid with velocities on face centres that are oriented relative to the grid while all tracer values and surface elevation values are cell centred.

Results from version 2.0 of the 4km-resolution regional-scale hydrodynamic model of the Great Barrier Reef (GBR4). This model is forced with BlueLink Ocean Modelling and Prediction System (OceanMAPS) model results on the ocean boundaries and Bureau of Meteorology ACCESS-R model for surface atmospheric data. The tide is introduced through 22 constituents derived from the global CSR tide model, and the river boundaries incorporate measured stream flow and temperature data from QLD DNRM's gauging stations for 22 rivers, and estimated flows and loads for 49 additional rivers. There are no known forcing problems. This model configuration and associated results dataset may be referred to as "GBR4_H2p0" according to the eReefs simulation naming protocol. The model runs in near-real-time mode, updating daily.

Results from version 2.0 of the 1km-resolution shelf-scale hydrodynamic model of the Great Barrier Reef (GBR1). This model is nested within version 2.0 of the 4km-resolution hydrodynamic model (GBR4) data at the ocean boundaries, uses the Bureau of Meteorology ACCESS-R model for surface atmospheric data and incorporates measured flow data from gauging stations at the river boundaries from QLD DNRM. This model configuration and associated results dataset may be referred to as "GBR1_H2p0" according to the eReefs simulation naming protocol. The model runs in near-real-time mode, updating daily.
-
Passive river tracer results derived from version 2.0 of the 4km-resolution regional-scale hydrodynamic model of the Great Barrier Reef (GBR4). This model configuration and associated results dataset may be referred to as "GBR4_H2p0_Rivers" according to the eReefs simulation naming protocol. The model runs in near-real-time mode, updating daily.
-
Results from version 3.1 of the 4km-resolution regional-scale biogeochemistry and sediments model of the Great Barrier Reef (GBR4), forced by version 2.0 of the 4km-resolution hydrodynamic model and with Furnas relationships for wet and dry tropics rivers as catchment inputs. This model configuration and associated results dataset may be referred to as "GBR4_H2p0_B3p1_Cfur_Dnrt" according to the eReefs biogeochemical simulation naming protocol. The model runs in near-real-time mode, updating daily.
