| 3 | This page documents the routine `PDAFomi_set_obs_diag` of PDAF, which was introduced with PDAF V3.0. This is part of the PDAF-OMI observation diagnostics module. |
| 4 | |
| 5 | The routine returns the number of observation types that are active in an assimilation run. |
| 6 | |
| 7 | Usually all PDAFomi_diag routines are called in `prepoststep_pdaf` where the observation information can be retrieved and analyzed. |
| 8 | |
| 9 | The interface is the following: |
| 10 | {{{ |
| 11 | SUBROUTINE PDAFomi_diag_nobs(nobstypes) |
| 12 | }}} |
| 13 | with the following argument: |
| 14 | {{{ |
| 15 | INTEGER, INTENT(inout) :: nobstypes ! Number of observation types |
| 16 | }}} |
| 17 | |
| 18 | *Note:** |
| 19 | * `nobstypes` is commonly used as the upper limit of a loop running over all observation types |
