- NIVAR : number of the variable to be perturbed at reading in input PREP file.
- NVAR : number of control variables.
- CVAR_M : names of control variables.
- CPREFIX_M : The prefix of the control variables (in PREP.txt file). Used only with VARASSIM.
- XSIGMA_M : covariances of background errors if B is fixed.
- XTPRT_M : The perturbation amplitudes.
- NNCV : selects the control variables to be used: if 1, used, if 0, not used.
- XSCALE_Q : scaling factor of Q matrix w.r.t. the initial B.
- XSCALE_QLAI : scaling factor of Q matrix w.r.t. the initial B, for LAI variable.
- CBIO : Name of Biomass variable
- CPREFIX_BIO : The prefix of the Biomass variable Used only in VARASSIM, useless in SODA/EKF.
- XALPH : coefficient for BIO_PASS, by patch.
