Application of Normalized Difference Water Index for Vegetation Water Content Monitoring from MODIS Data

Abstract:

The needs for vegetation water content monitoring originates from forest fire assessment: Firstly, the vegetation water content affects the forest ignition point; secondly, it affects the spread rate if the forest is on fire. Based on the above reasons, the inversion of vegetation water content in Da Hinggan Ling region of China was studied, using the Normalized Difference Water Index from MODIS (Moderate resolution Imaging Spectroradiometer) data, the relationship between the water content of vegetation and forest fire risk was preliminary analyzed.
