GBR 4km BioGeoChemical (BGC) model: Pre-Industrial scenario

The GBR4 BioGeoChemical (BGC) model builds on the GBR4 hydrodynamic model by modelling the water quality (nutrients and suspended sediment) and key ecological processes (coral, seagrass, plankton) that drive the water chemistry. This model allows us to better understand how water quality is affected by land runoff.

Files

The files for this model are grouped by time-steps.

NOTE: The variables from the original model were split into two files. The sediment variables can be found in the file with the -sed suffix, while the other variables are found in the file without the -sed suffix.

File description
ID Time range of the time dimension Time range of the file Description
daily-monthly 1 day 1 month This folder contains one file per month. The time dimension contains one value for each day of the month, each day represents an aggregation of the data for that day.
monthly-monthly 1 month 1 month This folder contains one file per month. The time dimension contains a single value per file, which represents an aggregation of all the data for the given month.
annual-annual 1 year 1 year This folder contains one file per year. The time dimension contains a single value per file, which represents an aggregation of all the data for the given year.
all-one All time All time This folder contains a single file. The time dimension contains a single value, which represents an aggregation of all the data that was produced for this model.
