Retrieval of Forest Fire History in Far East Asia by Remote Sensing and Its Analysis with Biomass Burning Simulation and Climate Anomalies

چکیده
This paper describes the creation of a forest fire history database for part of the Far East region of Asia using remotely sensed data, Advanced Very High Resolution Radiometer (AVHRR). The algorithm for burnt scar mapping utilizes an active fire detection technique together with detection of abrupt vegetation damage depicted by time series of the Normalized Difference Vegetation Index (NDVI). The forest fire database is stored in Geographic Information System (GIS) format, which permits easy utilization for further research. We used the forest fire database for three purposes: a) for simulating biomass burning, b) for estimating biophysical variables, and c) for correlating weather anomalies with the fire’s occurrence.

Forest Fire Potential Modeling and Simulation of its Extension Using Remote Sensing Data and GIS: (A Protected Area of Arasbaran)
Forest fire models are generally used in different aspects of fire management and are helpful in understanding and prediction of fire behavior. Forest fires cause a significant damage for public property by destroying a large tract of forest. This helps fire fighters to focus on an area with greater risk and to develop better substructure for fire fighter training and ultimately to plan fire-f...

Climate change has increased the area affected by forest fires each year in boreal North America1,2. Increases in burned area and fire frequency are expected to stimulate boreal carbon losses3–5. However, the impact of wildfires on carbon emissions is also affected by the severity of burning. How climate change influences the severity of biomass burning has proved difficult to assess. Here, we ...
