Abstract or Summary

Fire severity describes the immediate impact of fire on vegetation. The MODIS Fire severity product provides two classes – non-severe and severe. Non-severe fires only impacted the understorey while severe fires have impacted the tree canopy as well.

Data quality

Accuracy and quality of this product are subject to the overall accuracy of the burnt area and day of burn product along with the fire severity classification thresholds (Edwards et al, 2013 and 2015).

Validation status

Validation data was collected along transects through visual observation from a low flying helicopter. In 2015 a total of 1,750 km of transects have been covered, yielding a total of 749 fire severity validation points.

Algorithm summary

The fire severity algorithm builds on the MODIS Burnt Area and Approximate Day of Burn mapping, using the determined day of burn date to generate an intermediate product providing surface reflectances in the 7 MODIS land bands immediately pre- and post-fire. For fire severity classification thresholds are being applied to these reflectances.
