        <gco:CharacterString>Abstract: 30-day Gross Primary Productivity (GPP) estimated across the forest of Hyytiälä, Finland.&#13;
&#13;
Methods: The GPP maps are based on an empirical model that integrates and linearly correlate the RS-based vegetation index derived from Sentinel-2 images and in situ measurements of environmental variable with in situ measurements of GPP.&#13;
&#13;
For detailed information about the methodology:&#13;

&#13;
TechnicalInfo: 15-day and 30-day maps for 2019, 2020, and 2021.</gco:CharacterString>
