Time series of microwave derived products: Looking for disturbances in argentine Chaco Forest region

The objective of this article is to compare the trends of two vegetation indices (MODIS EVI (optical) and AMSR-E/ LPRM VOD (microwave)) using BFAST (Breaks For Additive Seasonal and Trend) method to monitor vegetation dynamics during the period 2002-2011. The comparison was carried out on a dry fore...

BFAST EVI VOD The objective of this article is to compare the trends of two vegetation indices (MODIS EVI (optical) and AMSR-E/ LPRM VOD (microwave)) using BFAST (Breaks For Additive Seasonal and Trend) method to monitor vegetation dynamics during the period 2002-2011. The comparison was carried out on a dry forest area in Argentina, Dry Chaco Forest, where deforestation is common. We show that BFAST detects several classes of changes in the analyzed timeframe (related to major phenological changes), accounting for abrupt disturbances and gradual trends. Differences between the classes of the major trend changes were found in the two time series analyzed. These results show the potential to combine optical and passive microwave indices to identify different classes of disturb. © 2015 IEEE.
