+Enhanced weathering module based on Strefler et al. (2018) which simulates the phosphorus release and CO,,2,, consumption by weathering of basalt and forsterite mineral grains. Grains are characterized by grain size diameter and mass applied. 
+
+Therefore the following additional forcing is needed: amount (g/m2/yr) and diameter (10^6^ m) of grains of basalt and forsterite). It can be either prescribed via run.def or via spatial explicit maps (See here for details [https://forge.ipsl.jussieu.fr/orchidee/wiki/DevelopmentActivities/inputRoutine]).
