GPP at FLUXNET Tier 1 sites from P-model

<p>Gross primary production, simulated by the P-model for each FLUXNET 2015 Tier 1 site. The model was driven by site-specific meteorological forcing and MODIS FPAR, extracted for the pixel corresponding to the site location.</p> <p>The CSV files contain simulated GPP values from different model setups conducted with the P-model and used for the publication Stocker et al.&nbsp;<em>Geosci. Mod. Dev. </em>(in review). One file is given for each temporal aggregation level (daily, 8-daily, annual, spatial [= mean annual value by site], and mean seasonal cycle [= mean per day-of-year]. Each file contains output from all model setups presented in Stocker et al. (2019), as given by column <em>setup</em>.</p> <p>The data differs slightly for each file:</p> <p><strong>Daily</strong>&nbsp;gpp_pmodel_fluxnet2015_stocker19gmd_daily.csv:</p> <ul> <li><em>sitename</em>: A character specifying the site ID following the naming given by FLUXNET 2015.</li> <li><em>date:&nbsp;</em>YYYY-MM-DD), date_start (in _8daily, YYYY-MM-DD specifying the first day of the respective 8-day period), year (in _annual, YYYY), doy (in __meanseason, specifying the day-of-year),</li> <li><em>gpp</em>: Simulated gross primary production, in units of g C m^-2 d^-1</li> <li><em>setup</em>: A character specifying the model setup name used in Stocker et al.
