Meteorological Influence on Space-time Distribution of Tomé-Açu (Eastern Amazon) Vegetation Cover using MODIS Products
The objective of this study was to analyze the seasonal behavior of vegetation cover and its response to the variation of meteorological elements in the microregion of Tomé-Açu, Eastern Amazon. The study area refers to the microregion of Tomé-Açu, Pará. MODIS sensor images were processed and analyzed on Google Earth Engine and QGIS 3.18.1 software to apply the NDVI, EVI and LAI vegetation indices. Results showed that the vegetation cover of the Microregion of Tomé-Açu has well-defined seasonality, with evident variation in vegetation indices throughout the year. The three indexes showed higher values in the dry season period and lower values in the rainy period of the year. Seasonality of vegetation cover showed a positive correlation with rainfall in the region, with higher values associated with rainfall occurring between 4 and 5 months prior to the observation.
