N2 - Eddy flux tower measurements, ground-based reflectance measurements, regionally modeled data, and data from the Moderate Resolution Imaging Spectroradiometer (MODIS) were used in this study of an ombrotrophic bog in southern Sweden. Linear regression analysis was used to investigate how the fraction of absorbed photosynthetically active radiation (FAPAR), light-use efficiency (epsiv), and gross primary productivity (GPP) are related to controlling variables. Results show that FAPAR and epsiv are not related and only weakly related to the normalized difference vegetation index (NDVI) and photochemical reflectance index (PRI), respectively. GPP is strongly related to insolation (E), absorbed photosynthetically active radiation (APAR), incoming photosynthetic photon flux density (PPFD), air temperature (Ta), regionally modeled PPFD (mPPFD), and MODIS land surface temperature (LST).
