#461 | Done | Updated several matlab/4dvar scripts | ||
Description |
Several scripts were updated in the matlab/4dvar repository. All the changes take into account the feedback that we got from users at the ROMS 4D-Var data assimilation workshop at UCSC last week.
The obsolete function 4dvar/inside.m is removed. It is too inefficient and inpolygon is far superior. The drivers to compute standard deviation (d_std.m, d_std_bry.m, d_std_frc.m, and d_std_unbalanced.m) were substantially improved to separate user preamble with generic code. It now uses dynamical field names in the structures. This made the scripts simpler and compact. The drivers d_ssh_obs.m and d_sst_obs.m were slightly modified to include new parameters to the obs_ijpos.m function call. Warning: the field names in the structure K were changed to facilitate dynamical field names: new old K.temp_bal K.deltaT K.salt_bal K.deltaS_b K.u_bal K.deltaU_b K.v_bal K.deltaV_b K.zeta_bal K.zeta_b K.ubar_val K.vbar_bal K.rho_ano For completeness, the K.ubar_bal and K.vbar_bal is computed by vertically integrating K.u_bal and K.v_bal. This is just for diagnostic purposes since they are not used in ROMS. I am very happy about the functionality of obs_ijpos.m and super_obs.m. These functions are critical when processing the observations. Many thanks to all you who gave me feedback in these processing scripts. |

#462 | Fixed | Corrected bug in standard deviation matlab scripts | ||
Description |
Corrected a bug in d_std.m, d_std_unbalanced.m, and d_std_frc.m. The record counter Rcount needs to be outside of the dynamical field structure for loop. Many thanks to Ha Joon Song for reporting this bug. Please update the matlab/4dvar directory. |

#463 | Done | Added matlab scripts to process UK Met Office observations | ||
Description |
I updated the matlab/4dvar repository and added two new scripts to process the UK Met Office datasets:
Various scripts were updated to allow concatenation of vectors consistent with the singleton dimension. This generalize the use of 4D-Var observation processing scripts. The utility/nc_read.m script was modified to allow processing string arrays with _FillValue. This is need to process the UK Met Office datasets. Corrected crucial bug in 4dvar/obs_depth.m when removing outliers in the observation structure. |
