The BoM re-forecasts dataset is a "fixed" dataset which means that the re-forecasts are produced once from a "frozen" version of the model and are used for a number of years to calibrate real-time forecast. The BoM re-forecasts consist of a 33-member ensemble run 6 times a month (1st/6th/11th/16th/21st/26th of each month) from1981 to 2013. The S2S database contains the full BoM re-forecast dataset.
As for the other models, boM re-forecasts are archived in the S2S database with 2 date attributes:
- hdate which corresponds to the actual starting date of the re-forecast
- date which correspond tot he ModelVersionDate.Since the BoM re-forecasts are "fixed" re-forecasts this ModelVersiondate is the same for all the re-forecasts and equal to 20140101. This variable will change when a new version of the model will be implemented.
