Abstract

Weather and climate are essential elements in understanding the risk of bushfire and managing the landscape to reduce risks. Spatially and temporally homogenous climate data are essential for optimising planned burning and land management strategies, and scenario planning for major fire events. This paper summarises the development of a homogeneous 41-year (1972–2012) hourly 4-km gridded climate dataset for the fire-prone state of Victoria, Australia. This dataset has been generated using a combination of mesoscale modelling, global reanalysis data, surface observations, and historic observed rainfall analyses. Outputs include surface weather variables such as hourly temperature, relative humidity, wind speed and wind direction. The output data are created using the Weather Research and Forecast (WRF) model. Outputs provide an almost limitless opportunity for hitherto unavailable analyses – such as identifying the frequency of extremes and identifying trends over the 41-year period. Furthermore, the hourly mesoscale wind fields provide a homogeneous long-period data set with which to drive fire spread models such as Phoenix. This paper describes generation of the dataset, evaluation of the outputs and highlights its use and relevance for fire management.
