This nested dataset provide the results from the generalized boosted modelling (GBMs) (also referred to as boosted regression tree (BRT) modelling) from Young et al. (2017). These models are designed to predict the spatial probability of fire occurrence at 4-km 2 spatial resolution and 30-yr temporal resolution in Alaskan boreal forest and tundra ecosystems. Within this nested dataset are five zip files. Together, the contents of these zip files provide the data and tools necessary to run the GBM models and recreate the results from Young et al. (2017). Further details on the specific contents in each zip file are provided in the README file for this nested dataset. Citation: Young, A.M., P. E. Higuera, P. A. Duffy, and F. S. Hu. 2017.
