This data set contains QUINCY simulation data and observational data for the manuscript "Evaluating the carbon and nitrogen cycles of the QUINCY terrestrial biosphere model using space-born optical remotely-sensed data", submitted to the Biogeosciences journal. The observation data includes in-situ observations of fraction of absorbed photosynthetically active radiation (fAPAR) for the Sodankylä site, and post-processed remote sensing leaf chlorophyll content data for the PLUMBER2 and GLOBAL sites. The post-processed remote sensing leaf chlorophyll data is based on the global leaf chlorophyll product by Dr. H. Croft (See Croft et al., 2020), and the product is derived from the MERIS satellite data.

The data set includes QUINCY simulation data for the PLUMBER2 and GLOBAL sites. Depending on the site, the simulated data covers years 1989-2018. The in-situ fAPAR for the Sodankylä site is for years 2021--2024. The post-processed remote sensing chlorophyll is for years 2003-2011, depending on the site.
