#### Description

The underlying dataset for this Enhanced Vegetation Index (EVI)
product is MODIS BRDF-corrected imagery (MCD43B4), which was gap-filled
using the approach outlined in Weiss et al. (2014) to eliminate missing
data caused by factors such as cloud cover. After gap-filling the data was clipped to thresholds of \[0, 1\] to ensure valid values.

The gap-filled 8-daily \~1km outputs are then aggregated temporally to produce monthly and annual products.
