18) Tehcnical news for the assimilation part SODA (C. Albergel, S. Munier).
These changes include:
- the names of the observation fields can be given in the namelist (new entry COBS_M in NAM_OBS).
- The EKF scheme can run with ISBA-DF, and can have WG1, WG2... WG8 as variable fields.
- No more limitation on Jacobians values (was [-0.1,1]) but on analysis increments instead ([-1,1] for LAI, [-0.1,0.1] for SM)
- new diagnostics: Jacobian values, innovations and residuals (additionally to the analysis increments)
