15-day and 30-day Gross Primary Productivity (GPP) estimated across the wetlands of the Doñana National Park, Spain.

The GPP maps are based on an empirical model integrates and linearly correlate the Red-Edge Index (CLr) derived from Sentinel-2 images and in situ measurements of precipitation with in situ measurements of GPP.
