Constituents:Nutrient Sub Module (NSM) Constituents, Project Cards

From Gsshawiki
Jump to: navigation, search

There are many project card that affect the running, reading, and writing of the NSM constituents. Much of the initialization of states is done through the NSM mapping tables, both the grid and stream mapping tables. The GSSHA/NSM linkage resides in research versions of the code only. NSM does not work with any GSSHA release version.
