gmult: LINKAGES gmult function

In araiho/linkages_package: A Linked Forest Productivity - Soil Process Model

Description

GMULT CALCULATES DEGREE DAY, SOIL MOISTURE, AND SOIL NITROGEN MULTIPLIERS USED IN SUBROUTINES BIRTH AND GROW BASED ON ON DEGD (SUPPLIED BY TEMPE), FJ (SUPPLIED BY MOIST), AND AVAILN (SUPPLIED BY DECOMP), RESPECTIVELY.
