FY10 Plan Continue collaborations and coordination with NCEP/EMC, NOAA/GSD, AFWA and NCAR. – Maryland staff – EMC visit Boulder Maintain Boulder Community Repository – Update, port and enhance Regression Test Suite – Improve the portability of the code – Carry out weekly regression tests – Sync with EMC GSI repository (EMC->Boulder) – Plan for Boulder->EMC syncing – Develop community tools: PrepBUFR converter GSI community support and management – GSI Community code release v2.0: April, 2010 (Tentative) – GSI Tutorial in June 28 – 30, 2010 in Boulder, CO – Form a Boulder GSI committee, which provides guidance to the GSI support, testing and evaluation – Maintain and update the Boulder Community GSI Code Management Plan – Setup administrative (?) structure for GSI management – Coordinate T&E activities – Update GSI User’s Guide v2.0 – Provide support to the community including GSI-help, GSI webpage, online documentation and online tutorial – Present Boulder GSI work at national and international conferences

FY10 Plan GSI T & E DTC will  Set up the FY2010 AFWA GSI Testbed, based on the recommendation from the DTC FY2009 GSI T&E report;  Carry out a baseline experiment without GSI (NODA run) using the latest WPS and ARW, available in Spring 2010, as a reference for evaluating GSI experiments;  Test and evaluate the latest GSI, available in Spring 2010, using the testbed;  Conduct impact studies to assess impact from certain data types;  Check and test QC procedures;  Deliver a report to AFWA summarizing the test results and recommendations.  Further develop the end-to-end scripts;  Develop utilities to read and display outputs from GSI, WRF and MET

FY10 Plan Milestones (Deliverable): – GSI Community code release v2.0: April, 2010 (Tentative) – GSI Tutorial in June 28 – 30, 2010 in Boulder, CO – Updated GSI User’s Guide – GSI committees – T&E activities report

FY10 Plan Budget (AFWA+NOAA) Salary: Huang0.1 FTE AFWA FTE NOAA Shao 1.0 FTE AFWA Crosby 1.0 FTE AFWA Park 0.4 FTE AFWA Hu0.50 FTE NOAA Stark0.50 FTE NOAA Carson?? Total2.5 FTE AFWA1.15+?? FTE NOAA Travels: – 4 x DC-Denver – 2 x Omaha – 2 x AMS conference

FY10 Plan Extra tasks ( FTE) Development community tools (samples) to read GSI and display outputs (e.g., GSI’s binary outputs). DTC GSI Testbed – Expand the AFWA GSI Testbed:  Compute a new (ARW) BE from NODA, carry out singe ob experiments and perform initial BE tuning, in collaboration with MMM colleagues;  Test and evaluate the ARW BE (and its tuning) using the testbed, in collaboration with MMM colleagues;  Develop utilities to read and display outputs from GSI, WRF and MET;  provide documentation of the utilities to AFWA.  Set up a GSD GSI Testbed:  test GSI capability/configuration for RR also using WRF-ARW  initial capability – impact for cloud analysis using GOES and METAR observations  extendable to observation impact for other platforms by DTC community
