  4. Hydrologic Modeling Group General R&D Topics to Meet NOAA/NWS Goals Improved Calibration Tools -CAP -ICP Improved Site Specific Model Energy Budget Snow Models (SNODAS) Statistical Distributed Flash flood model Distributed Snow-17 - Better Forecast Accuracy - More Specific and Timely information on Fast Rising Floods Improved Calibration Science -Multi-objective -Soil moisture + Other obs. Distributed Rainfall/Runoff Models Improved Initial Model Parameters New rainfall-runoff Models -DMIP 1,2 - Prototype Products for Water Resources Program Soil Moisture Soil Tempature Surface Water

  5. SLF Proposed Projects Thursday October 12, 2006 1. Calibration R&D 2.Prototype water resource products

  6. 1. Calibration R&DFY07 Tasks • Need • Must deliver calibration tools to keep pace with new science releases, e.g., distributed modeling, ability to compute soil moisture, finer time/space scales etc. • Reduce overall effort to calibrate models (all models need calibration!) • Meet AHPS goals

  7. FY06 AHPS FundingCalibration R&D

  8. 1. Calibration R&DFY06 Accomplishments • Soil moisture and calibration • Submit paper on Simplified Line Search (SLS) to OHD review • Presented findings at major int’l. hydrology conference • Explored use of X-DMS as a way to look for spatially uniform precip for lumped models. (DMIP 2)

  9. ObservedSimulated Discharge Objective function: Minimize errors ObservedSimulated Soil Moisture 0-25 cm depth ObservedSimulated Soil Moisture 25-75 cm depth

  10. 1. Calibration R&D FY07 Tasks 1.1 Incorporate soil moisture, temperature into lumped and distributed SAC calibration strategy • Develop ‘proof of concept’ narrative • Explore appropriate weighted objective functions • Explore other search algorithms • Develop appropriate averaging of soil moisture, temperature over desired area • Deliverables • Guidelines on how to do it • Prototype calibration tools • Requirements for ICP enhancements

  11. 1. Calibration R&D FY07 Tasks 1.2 Enhance Existing Statistics Program: STAT-Q What is STAT-Q? -Analyzes two time series for run-period and event statistics; prototype sent to all RFC’s several years ago, sub-daily time steps -Complements NWSRFS STAT-QME operation (limited to daily flows) 1.2.1 Tasks • Add ability to analyze multiple time series (more than current two) • Add ability to output to Excel, ‘R’ etc for easy plotting • Create HOSIP documents for AWIPS 1.2.2 Deliverables • Updated prototype tool and documentation • HOSIP documents for AWIPS delivery

  12. 1. Calibration R&D FY07 Tasks 1.3 Auto-calibration of lumped and distributed models Proposed Approach: Auto calb. algorithm & a priori parameters 1.3.1 Tasks - Modify distributed model to efficiently link to auto-calb procedures (current approach: manual scaling of parameters) • Explore appropriate multi-time scale objective functions • Determine appropriate search algorithms for this approach • Develop requirements to add new algorithms and new obj. functions to AWIPS NWSRFS OPT3 program 1.3.2 Deliverables • Prototype distributed, lumped calibration tools • Requirements for ICP enhancements for lumped tools • Requirements for modifying NWSRFS OPT3 to include new items Minimize K= hours, days, months,…

  13. 1. Calibration R&D Cost Estimates

  14. Prototype Water Resource Products • - Motivation 1. FY07 Hydrology Program Annual Guidance Memorandum Short- to Long-Term Forecast Services • Produce water resource information fields from distributed models to support water resource management and environmental stewardship 2. NOAA AGM 2008-2012, page 8

  15. Prototype Water Resource Products • - Motivation, cont’d 3. Existing RFC needs: ‘We are also interested in the modified SAC model, particularly since we are somewhat “on the hook” to try to develop a soil moisture product (graphic) which conveys the current model states. This has been a recurring request (several years) which we have delayed, but was recently placed on a list in Central Region which specifies that we begin attempts to address this.” John Halquist, March 18, 2005

  19. FY07 Tasks • Continued evaluation of prototype products • Illinois (other) soil moisture data • Soil temperature data • Formal analysis of results from New Mexico rangeland study. • Contribute to and leverage related projects • NLDAS: NCEP sponsored CONUS scale runs of several models • Leverage independent analyses of models and data • Compare NLDAS coarse scale to OHD fine-scale products • Analyze surface water storage as new product
