Multi-temporal analysis of MODIS Land Products over the Amazon region

In a global warming scenario there is an increase interest in examining climate trends at specific biomes such as the tropical rainforest biome. The Amazonian region is the largest carbon sink, so changes in this area are expected to have a direct impact over the climate change. In this work we analyse the temporal evolution (trends and anomalies) of different land parameters from 2001 to 2010 over the Amazonian forest. For this purpose, we used Moderate Resolution Imaging Spectroradiometer (MODIS) Land Products at 0.05° latitude/longitude Climate Modeling Grid (CMG), namely, combined Terra/Aqua 16-day Albedo (MCD43C3), Terra monthly Land Surface Temperature & Emissivity (MOD11C3), Terra monthly Vegetation Indices (MOD13C2), and combined Terra/Aqua yearly Land Cover product (MCD12C1. Results show an anomalous widespread warming over the study area, and also a decadal decrease in vegetation indices (EVI and NDVI). Mean value of surface albedo do not provide a significant trend, but some regions show an anomalous increase.
