28 28 (% style="font-weight: normal;" %)We are at the early stages of work developing a ML-based vegetation model which uses outputs of the Bureau's seasonal prediction ACCESS-S.The purpose of this work is twofold:

30 -(% style="font-weight: normal;" %) -Investigate the possibility of making predictions of vegetation ​characteristics in the coming weeks and seasons using model outputs as predictors. Forecasts of vegetation could have potential use for a number of sectors including fire agencies and agriculture

32 -(% style="font-weight: normal;" %) -Attempt to use the vegetation model we develop to periodically update the vegetation ancillary file used in model runs. Currently ACCESS-S1 uses a static vegetation file. We plan to investigate what possible skill gains could be got from a more dynamic representation of vegetation, and then to try updating the vegetation ancillary of the model every N timesteps by passing it through our vegetation model, along with the latest model parameters.

34 34 (% style="font-weight: normal;" %)We intend to start by trying an LSTM Neural Network for the vegetation model, potentially also including some convolutional layers. We will however be investigating what is most effective as we go. Initially we will be training using the ACCESS-S1 hindcast, however if a larger training set is needed we may investigate using a larger set to train, followed by transfer learning techniques to update the model to ACCESS-S.
