1) compute_national_nitrogen_response_curves_all2.R

R-script to optimize the N distribution for different models (or the ensemble), optimization targets and crops. 

2) job description files for submitting data to PIK cluster

All *.jcf files can be used to submit the optimization jobs to the PIK cluster via the SLURM system (sbatch *.jcf)

3) results

The file 220324_all_scenarios.xlsx contains the main results for the GGCMI ensemble. It was combined by hand from the original csv files outputted by the R script.
The other *.xlsx files contain the results for individual GGCMs (name given in file name) for the sensitivity analysis.
