Updates, change notes and bug fixes

WRF2 has been implemented at 24-km (higher resolution planned after some evaluation of current runs). WRF2 results (all physics) are markedly different (often drier) than WRF1 or MM5 runs at the same resolution. For more information on the current configuration, click here.

Changes/fixes:

• WRF_Eta[h,i,j] output only every 3h. Fixed Jan. 12
• Some animation times are still missing. Fixed Jan. 12
• Problem plotting WRF[a...g]: output now every hour Fixed Jan. 10
• Animation, dprog/dt problems showing blank frames - Fixed Jan. 6
• Expanded dProg/dt. Fixed Jan. 3.

Known issues:

• WRF-12 km w/Eta IC seems to be running on 12h-old data.
• Workstation eta runs are not being plotted properly.
• Workstation eta runs need to be remapped to the same projection used for other models.

Planned short-term changes:

• More fields. Shown now are selected output fields that are available for all models - MM5, workstation Eta, and WRF. Forecast soundings are high on the list.
• Alter MM5 domain to match that of the WRF and Workstation Eta.

Coming up:

• Ensemble plots, utilizing all current and earlier runs. Included will be spaghetti and probability plots. Comprehensive ensemble assessment is necessary as well.
• Station time series data for selected cities, from all models.
• Implement ARPS and RSM (underway). Resources currently exist to make up to six additional 24-km runs (total for both models), during the 00z cycle.
• Verification, to analyses and observations.
• Ensemble members assessing observational uncertainty. Ongoing research on the design and assessment of Perturbed Observations (PO), Breeding of Growing Modes (BGM), and perturbed lateral boundary conditions will be applied to our regional ensemble modeling effort.
