14.4.7 Diagnostic intervals

Namelist /diagn/

These variables are used for setting diagnostic intervals and related items. The interval is a real number and has a Boolean variable (switch) associated with it which is set by the time manager every time step. The Boolean variable is set to true when the model integration time mod the interval is less than or equal to half a timestep. Otherwise, it is set false.

To add a switch, three variables must be added to the common block in switch.h: an interval (real numbner), a Boolean variable which acts as the logical switch, and an integer variable used as an index within module tmngr. Refer to include file switch.h to see the structure. Refer to the section where alarms are set within module tmngr for examples of how to implement new switches.

•  tsiint = interval in days between writing time step integrals. This is used with option time_step_monitor.

•  tavgint = interval in days between writing data for use with option tracer_averages.

•  itavg = Boolean for writing regional mask when used with option tracer_averages. It should be set true on the first time step of the first run and false thereafter. This allows datasets from multiple runs to be concatenated without regional mask information being duplicated.

•  tmbint = interval in days between writing data for option meridional_tracer_budget.

•  tmbper = period in days for producing time averaged data for use with option meridional_tracer_budget. This averaging period may be set shorter than the interval tmbint.

•  itmb = Boolean for writing ``msktmb'' when used with option meridional_tracer_budget.It should be set true on the first time step of the first run and false thereafter. This allows datasets from multiple runs to be concatenated without regional mask information being duplicated.

•  stabint = interval in days between doing stability analysis for use with option stability_tests.

•  cflons = starting longitude (deg) for computing data for use with option stability_tests.

•  cflats = starting latitude (deg) for computing data for use with option stability_tests.

•  cflate = ending latitude (deg) for computing data for use with option stability_tests.

•  cfldps = starting depth (cm) for computing data for use with option stability_tests.

•  cfldpe = ending depth (cm) for computing data for use with option stability_tests.

•  maxcfl = maximum number of CFL violations before quitting for use with option stability_tests.

•  zmbcint = interval in days between writing data for option show_zonal_mean_of_sbc.

•  prslon = starting longitude (deg) for writing (xz) data for use with option matrix_sections.

•  prelon = ending longitude (deg) for writing (xz) data for use with option matrix_sections.

•  prsdpt = starting depth (cm) for writing (xz) data for use with option matrix_sections.

•  predpt = ending depth (cm) for writing (xz) data for use with option matrix_sections.

•  slatxy = starting latitude (deg) for writing (xy) data for use with option matrix_sections.

•  elatxy = ending latitude (deg) for writing (xy) data for use with option matrix_sections.

•  dspint = interval in days between writing data for use with option diagnostic_surf_height.

•  dspper = period in days for producing time averaged data for use with option diagnostic_surf_height. This averaging period may be set shorter than the interval dspint.

•  snapint = interval in days between writing data for use with option snapshots.

•  snapls = starting latitude (deg) for writing data for use with option snapshots.

•  snaple = ending latitude (deg) for writing data for use with option snapshots.

•  snapds = starting depth (cm) for writing data for use with option snapshots.

•  snapde = ending depth (cm) for writing data for use with option snapshots.

•  timavgint = interval in days between writing data for use with option time_averages.
