We aimed to a simple and constant parameterization of senescence, but it Resiquimod might be worthwhile to vary the dscn along the latitudinal gradient. However, in order to be able to model the dependency of dscn on latitude or meteorological factors and not only fit it to data, one would need more knowledge about what triggers the phenological events, such as senescence, of peatland vegetation ( Richardson et al., 2013). We thus decided to keep a constant dscn in the present study and set the date to 218 (6 August). This was supported by Wilson et al. (2007) since 218 was the mean in the range of peak sedge LAI dates found in their study that also utilized LAI data from Lakkasuo. When simulating the LAI of Lompolojänkkä, our model started senescence too late compared with the observations, especially in 2011 ( Fig. 5). This result was not a great surprise since the senescence start date can be expected to depend on the adaptation to local photothermal conditions ( Clevering et al., 2001) and so to be earlier in northern than in southern Finland.
