EVI MAIAC over the Amazon Forests filtered by Fourier Transform

Inter-annual monthly mean values of the enhanced vegetation index (EVI) over the Amazon forest obtained by the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor, on board the Terra and Aqua satellites (EOS AM, NASA); processed with multiangle implementation of atmospheric correction algorithm (MAIAC) and filtered using the Fourier Transform (FT) to keep only the annual and bis-annual frequencies that compose the EVI signal.<div>The image is a .tif with 12 bands corresponding to the month of the year (first is january)</div

Spatial pattern of climate controls on leaf growing season initiation in South American tropical forests.

<p>Locations of the sites with monthly litterfall productivity measurements are indicated by blue numbers.</p

Description of the study sites for litterfall measurements, adapted from [25].

<p>For each site, reference of the articles, country, full site name and geographical coordinates (longitude and latitude in decimal degrees) are reported. The next columns reports the type of measurements, only leaf fall (YES) or total litterfall (NO), the number of traps, the trap size, the total area sampled, the mean litterfall productivity in Mg.ha⁻¹.year⁻¹ and the duration.</p

Seasonal leaf production (EVI increase) and associated litterfall productivity in 16 tropical forest sites.
