Description
Context
Sea-ice impacts the amount of PAR that reaches the surface of the ocean. Because the sea-ice concentration in a grid cell represents the average of the sea-ice extent over that grid cell, a specific treatment should be embedded in biogeochemical models.
Analysis
The current scheme in PISCES uses the average PAR that is computed in the sea-ice model. As a consequence, it assumes that PAR is identical in the sea-ice covered part of the grid-cell and in the ice-free ocean within the same grid cell. Currently, PISCES computes PP from the mean PAR over the grid cell which is different (larger) than the average of the PP over the grid cell (see Long et al., 2015).
Fix
See attached routines.
