1 Update to COPC 4 – 5 November 2014 Dave McCarren, NUOPC DPM

2 2 NUOPC National Unified Operational Prediction Capability 2 Agenda  National ESPC  NUOPC UEO Committee  NUOPC CMA Committee Update  Questions and Discussion

3 The Earth System Prediction Capability (ESPC) Inter-agency Project

4 The National Earth System Prediction Capability ESPC 4 National ESPC Strategy Whitepaper Final version sent to Liaisons incorporating Agency feedback and ESG comments 25 Aug ESG Action Item: Continue working on the National ESPC Strategy whitepaper and publish as a response to the 2006 BAMS “Uncoordinated Giant” article, highlighting NUOPC successes. Draft proposal for BAMS sent to Liaisons 25 Aug ESG Action Item: Create a National ESPC Strategy 2-pager to distribute appropriately to get support for the project. National ESPC staff drafting Strategy 2-pager for distribution to Liaisons

5 National Unified Operational Prediction Capability NUOPC 5 UEO Committee Update

6 National Unified Operational Prediction Capability NUOPC 6 Unified Ensemble Operations UEO continuing efforts to collect wave ensemble metrics; NAWES providing updates at UEO and NAEFS telecons NUOPC metrics from NCEP and FNMOC briefed to ESG 2014 ensemble User Survey summaries briefed to Navy and AF; working NOAA summary

7 5-day forecast for surface wind (U) 10-day forecast for surface wind (U)

8 NH T2m

9 NA T2m

10 Relative performance of models varies by forecast lead time and region, but NUOPC is consistently best for all lead times and regions.

11 FNMOC is now providing all Centers’ models and multi-model NUOPC products to its customers. (FNMOC)(NCEP)(Canadian)(FNMOC)(NCEP) CMC added to NUOPC at FNMOC

13 National Unified Operational Prediction Capability NUOPC 13 CMA Committee Update

14 National Unified Operational Prediction Capability NUOPC NUOPC Common Model Architecture CMA working final edit of manuscript for ESPS paper to BAMS Added NUOPC Compliant Components to ESPS Coupled Modeling Systems; briefed to ESG Just got HYCOM in CESM running in a HYCOM-ICE configuration; not yet scientifically valid but that will take some time. ESMF release in Nov 2014 PI Group drafting high-level requirements document for Physics Driver interface design and modernized Kalnay Rules paper for AMS

15 National Unified Operational Prediction Capability NUOPC 15 ESPS is a collection of NUOPC- compliant Earth system component and model codes o interoperable, documented, available to credentialed users Implementation is part of NOPP project awarded under ESPC o “An Integration and Evaluation Framework for ESPC Coupled Models” ESPS interfaces are based on ESMF and the NUOPC Layer The NUOPC Interoperability Layer: o a set of rules for coding ESMF- compliant Earth system component and coupled models ESPS website with draft inclusion criteria and list of candidate models (Coupled, Atmosphere, Ocean, Ice, and Wave): ojects/esps/ DeLuca et al (draft) Earth System Modeling Framework (ESMF) and the Earth System Prediction Suite (ESPS) Coupled Modeling Systems NEMSCFSv3 COAMPS /COAMP S-TC NavGEM- HYCOM- CICE GEOS-5ModelECESM Driver 2015 Atmospheres GFS/GSM NMMB CAM 2014 FIM2014 GEOS-5 FV 2015 ModelE Atm 2014 COAMPS Atm NavGEM NEPTUNE 2015 WRF 2014 Oceans MOM5 HYCOM NCOM MPAS-O TBD POP POM2015 Ice CICE 2014 Wave WW32014 SWAN LEGEND Compliant(Completion date)In progress (Completion date) Candidate Compliant since 3/2014
