Generic User parameters, NUSER values are expected.

From roms.in we have the following:

• NUSER is the number (integer) of user parameters to consider. USER is a vector containing NUSER user parameters (real array).
  NUSER = 0
  USER = 0.d0
  This array is primarily used with the SANITY_CHECK to test the correctness of the tangent linear adjoint models. It contains the model variable and grid point to perturb:
  ! INT(user(1)): tangent state variable to perturb
  ! INT(user(2)): adjoint state variable to perturb
  ! [ isFsur = 1 ] free-surface
  ! [ isUbar = 2 ] 2D U-momentum
  ! [ isVbar = 3 ] 2D V-momentum
  ! [ isUvel = 4 ] 3D U-momentum
  ! [ isVvel = 5 ] 3D V-momentum
  ! [ isTvar = 6 ] First tracer (temperature)
  ! [ ... ] ...
  ! [ isTvar = ? ] Last tracer
  !
  ! INT(user(3)): I-index of tangent variable to perturb
  ! INT(user(4)): I-index of adjoint variable to perturb
  ! INT(user(5)): J-index of tangent variable to perturb
  ! INT(user(6)): J-index of adjoint variable to perturb
  ! INT(user(7)): K-index of tangent variable to perturb, if 3D
  ! INT(user(8)): K-index of adjoint variable to perturb, if 3D
  Set tangent and adjoint parameters to the same values if perturbing and reporting the same variable.

• This parameter could also be used to adjust constants in analytical functions at run time.
