Fire weather potential

Weather has a significant influence on fire behaviour. Wind, ambient temperature, humidity, precipitation and derived values from these are key parameters for calculating fire rate of spread, available fuel load and consumable fuel.

Hot, windy, dry days as well as extended dry periods have the potential to significantly amplify fire rate of spread and Fireline intensity.

Data

Weather is defined by both a historical weather reanalysis dataset (ERA5, baseline scenario) drawing on hourly concurrent data and a climate biased future weather dataset (based on 6 Global Climate Models and 2 Representative Concentrations Pathways from CMIP5, projected scenarios).
