Global Re-Analysis of Vegetation

Our previous work on the remote-sensing based data assimilation framework has been extended to regional and global scales. It employs a subgrid‐scale representation of plant functional types (PFTs) and elevation classes to generate a globally applicable phenological parameter set. We are able to predict (or hindcast) a 50 year long (1960–2009) daily 1° × 1° global phenology climate data record with a mean FPAR and LAI prediction error of 0.065 (−) and 0.34 (m^2 m^−2).

The data set as well as the underlying data assimilation and prediction code with all parameters are available publicly as open source:
