    Vegetation optical depth as a key predictor for fire risk escalation by Dinuka Kankanige, Yi Y. Liu, Ashish Sharma

    Published 2025-05-01
    “…This study investigates whether vegetation parameters can be utilized in fire risk prediction in the absence of fire weather information, and how they can be utilized to effectively reflect on the fire risk increment from a minimum point, which is the concern in bushfire occurrence. Using the McArthur Forest Fire Danger Index (FFDI) as a measure of fire danger, a clear association with the satellite-observed vegetation optical depth (VOD) was noted for segments illustrating risk increment. …”
