- Abstract
The article presents a study that aims to develop a simple, fast, and automated ecosystem disturbance detection algorithm for global application. The algorithm was developed using Moderate Resolution Imaging Spectroradiometer (MODIS)/Aqua Land Surface Temperature (LST) and Terra/MODIS Enhanced Vegetation Index (EVI) data from 2003 to 2004. Using the annual maximum composite LST data, changes in land-surface energy partitioning were observed. The potential disturbance events from the algorithm were then verified by demonstration of close association with historical wildfire events. The findings suggest that the algorithm developed is capable of detecting the location and spatial extent of wildfire.
