GPP at FLUXNET Tier 1 sites from P-model

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.

The CSV files contain simulated GPP values from different model setups conducted with the P-model and used for the publication Stocker et al. Geosci. Mod. Dev. (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 setup.

The data differs slightly for each file:

Daily gpp_pmodel_fluxnet2015_stocker19gmd_daily.csv:

sitename: A character specifying the site ID following the naming given by FLUXNET 2015.

date: 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),

gpp: Simulated gross primary production, in units of g C m-2 d-1

setup: A character specifying the model setup name used in Stocker et al. (2019). See also below.

8-daily gpp_pmodel_fluxnet2015_stocker19gmd_8daily.csv:
