! Input parameters for NUM model generalists !
! ======================================================================!
! This file contains the input parameters for the NUM Model. !
! The parameters are read in in the different initialization !
! routines with a call to read_namelist(). The file contains several !
! different namelists initialized by !
! &input_namelist !
!and ended by !
! / !
! Comments can be added with an exclamation mark (!) !
! A descrition of each parameter is provided alongside the parameter !
! along with the units in square brackets ([unit]). A glossary is found !
! at the end of the file where standard values for each parameter is !
! given in curly brackets ({standard value}). !

! kBasal = Factor for basal metabolism {0.006}. This value represents basal metabolism at
! starvation. Following Kiørboe (1985) the starvation metabolism is approximatly
! 0.2*0.18=0.036 times the maximum metabolism (kSDA). Increased to 0.01 to avoid
! too long transients.
! kSDA = Factor for SDA metabolism (Serra-Pompei 2020) {0.16}. This value assumes that the
! data in Kiørboe and Hirst (2014) are for fully fed copepods.
