1. FAA AWRP Icing

2. Tasks and POP Our FY2013 is Jan’13 through Mar’14 (15 mo) Tasks: 1.MICRO 2.IPA 3.CIP/FIP-HiRes 4.Dual-pol NEXRAD

3. MICRO Accomplishments so far First case study proving to be useful for many, many applications “pseudo climatology” Testing data inputs Testing accretion codes for cloud and large drop icing aloft and at the surface (yes, we know…) Completed draft development plan Gathering data for additional case studies – in collaboration with our Xcel Energy and AWRT work Corrected satellite icing product (part of MICRO input) Completed metar_mapper upgrades (needed for high- resolution MICRO) Completed draft ConOps (discussion tomorrow)

4. Plans (thru 3/31/14) Get a near-real-time version running at NCAR Output available internally for “eyeball time” Complete 2-4 additional case studies These are still needed to assess which data and model inputs produce greatest improvements in icing diagnosis Determine priority data ingest upgrades and commence work on those Actually, progress is a mix of priorities, bang-for- the-buck and opportunities Many problems with staff allocations among all our icing projects MICRO

5. Issues Need to determine (with input from ISG and others) what outputs are needed and desired Primary Appendix C/O conditions? Exceedance of those conditions? And probability of above? “Standard” accretion rate? Secondary Liquid water content? Drop size metric? Additional severity information? We need in situ data in the 2-3 year time frame (Wednesday’s discussion) MICRO

6. IPA

7. FY13 Accomplishments Delivered 40-km CIP-HiRes output and bug fixes to AWC in April Developed upgrade list and schedule and are working to that Quality Assessment PDT verified winter 2013 data set and compared with operational CIP/FIP Technical Review Panel 15 November Monitor CIP/FIP-HiRes

8. Plans (thru 3/31/14) Release upgraded version end of November Internal release only (V1.1) Work on high-priority upgrades for April release (V1.2) Issues Need migration plan for CIP/FIP -> MICRO Do we? Monitor CIP/FIP-HiRes

9. Dual-pol NEXRAD

10. FY13 Accomplishments Codebase refactored to split off 'dual-pol' and 'single-pol' streams, extensively tested, delivered code description document ~20 cases vetted and most input data collected ~5 cases processed through new code with initial analysis Wiki page shows details of the cases and summarizes results Plans (thru 3/31/14) Incorporate input into CIP cases to assess improvements Dual-Pol NEXRAD

11. Misc. Just submitted six abstracts to the AIAA 2014 Aviation and Astronautics Forum Are working closely with NSSL on MRMS Aviation Hazard product (AWRP work) Are working not-so-closely with MIT-LL on IHL deployment Work Mark M’s airborne sensor work into MICRO? How can we get icing (and other small-end GA concerns) back in the forefront of public discussions (such as FPAW)?

12. FY2014 Proposal Our FY2014 is Apr’14 – Mar’15 Tasks: 1.MICRO 2.IPA 3.Outreach 4.CIP/FIP-HiRes 5.Dual-Pol NEXRAD 6.Global CIP

13. MICRO 14.4.1.1Improve Numerical Weather Prediction Models (NWP) by developing means to estimate icing-related parameters, construct a baseline clear sky satellite mask and research statistical bias correction methods. 14.4.1.2Develop a better algorithm structure that is data-driven, flexible and agile. 14.4.1.3Develop a means, coordinating with the Quality Assessment Product Development Team (QAPDT) and Aviation Weather Demonstration and Evaluation (AWDE) services, to evaluate upgrades and link to quality assessment evaluation tools. 14.4.1.4Prepare an experimental version of the MICRO algorithm for the Aviation Weather Test-bed (AWT) to be displayed winter 2014-2015. Output will be made available to the QAPDT for evaluation. The algorithm will be run either at NCAR or AWC, depending on resources. 14.4.1.5Coordinate with AWDE services to determine what type of evaluation would be needed from AWC forecasters. 14.4.1.6Ensure coordination of MICRO research with TAIWIS and HIWC efforts.

14. IPA 14.4.2.1 Continue development of IPA Diagnosis and Forecast product and have experimental version ready for testing at the AWT or Alaska Aviation Weather Unit (AAWU), and in-house at NCAR for the winter of 2014-2015. 14.4.2.2 Recommend the final operational platform for the product (AWC and/or AAWU), the pathway to operations, and coordinate integration with AAWU operations. 14.4.2.3 Working with QAPDT, plan and support QA assessment of IPA Forecast product. 14.4.2.4 Consider Human Factors Assessment to determine optimum way to display IPA product. 14.4.2.5 Ensure coordination of IPA research with TAIWIS and MICRO efforts. 14.4.2.6 If 2013 research proves successful, begin incorporation of high resolution modeling (HRRR-AK) and Polar Orbiting Environmental Satellite (POES) data into product (Depending on funding availability could be Lower Priority than 1-5)

15. Outreach 14.4.3.1Determine who the users are, what their needs are, and what additional icing applications could benefit from inclusion in MICRO and IPA development (e.g. TAIWIS, wind energy, other structural icing, etc). 14.4.3.2 Study viability of conducting an In-flight Icing User’s Technical Interchange Meeting to include Internal and External NAS Users to assess needs of icing community. 14.4.3.3Conduct In-flight Icing User’s Technical Interchange Meeting 14.4.3.4Collate input from meeting and determine which ideas and concepts are feasible for future product development 14.4.3.5Incorporate input into products as appropriate

16. Outreach 14.4.3.E1Jun’14 Establish time and location for In- flight Icing User’s Technical Interchange Meeting 14.4.3.E2by Sep’14 In-flight Icing User’s Technical Interchange Meeting (if determined feasible) 14.4.3.E3by Sep’14 Informal gathering of user information (if meeting is determined not feasible) 14.4.3.E4Mar’14 Progress report

18. Dual-Pol NEXRAD 14.4.5.1 Work with AWRT PDT to define requirements and integrate Dual-Pol icing data into MRMS. 14.4.5.2 Evaluate if Dual-pol icing data will improve CIP/FIP and integrate dual-pol icing data into CIP/FIP HiRes. 14.4.5.3Begin to utilize Dual-Pol data into MICRO development. 14.4.5.4Ensure coordination of Dual-Pol research with TAIWIS and HIWC efforts 14.4.5.5Add features from Dual-Pol icing research into original IHL algorithm.
