All simulations from 2017 onwards have the following naming structure:
GBRg – Model grid with g = approximate grid resolution in kilometres.
Hhhh – Hydrodynamic model, hhh = model version.
Bbbb – Biogeochemical model, bbb = model version.
Cccc – Catchment model, ccc = load specification.
Dddd – Model deployment.
H1p85 – Hydrodynamic run for SIEF report: contained salinity errors in 2015 – grid contains only 22 rivers.
H2p0 – No known forcing problems. 70 rivers included as boundaries, but only 22 have flows and loads. Fixed a rainfall forcing issue.
B1p0 – This is the original biogeochemical model. The simulations for the SIEF report in Jan 2016, and which have been referred to previously as v926, used this version.
B1p9 – More accurate optical calculations; Normanby – particulate and dissolved loads corrected; Sediment tracer “Dust” added; Oxygen mass conservation part of diagnostics.
B2p0 – Added deep seagrass species, seagrass mortality enhanced by bottom shear stress and nutrient uptake by seagrass leaves; spectral light forcing benthic microalgae; carbon chemistry calculations in sediment and using time-varying atmospheric pCO2; distinguish carbonate and non-carbonate fine sediments; in-line calculation of simulated satellite products; VIIRS satellite comparison; implement ecological processes on boundary cells; dynamic porosity in ecological process calculations; calculation of turbidity using optical model.
B2p1 – Added new coral bleaching processes.
GBR4_H1p85_B1p0_Cbas_Dhnd – The simulation run for the 2016 SIEF report that was the first publicly-available long run of the full coupled hydrodynamic – biogeochemical model (formally known as gbr926).
GBR4_H2p0_B2p0_Chyd_Dhnd – Second publicly-release (mid 2017) long run being used for GBRF resilience and NESP TWQ Hub projects.
GBR4_H2p0_B1p9_Chyd_Dran – First application of BGC data assimilation that is being used for GBR report card 7.
