An Independent Technical Review Process for Government Developed Models HASDM As a Case Study Michael J. Gabor
Outline • Introduction • JAWG • HASDM • Technical Review Process • Lessons Learned • Summary and Conclusions
Introduction • U.S. Space Command • JAWG • HASDM
JAWG • Originally associated with SSWG • Led by USSPACE/J33 and AN • Then leadership transferred to AN • Coordinate R&D of SSA (especially space surveillance) between services • Attempted USSPACE Astro standards
HASDM • DCA • Use catalog to determine common corrections that are expected to account for common atmospheric characteristics • Various approaches to DCA exist • HASDM • SSULI - Special Sensor Ultraviolet Limb Imager (NRL) • Nazarenko • EDR (Storz) • E10.7 • New solar flux proxy intended to replace F10.7 • Based on satellite EUV measurements
Technical Review Process • Pre-meeting info dissemination • Pre-meeting Q&A • Briefings • Q&A • Feedback forms • Organizational memos • Feedback filtered for biases, inaccuracies, ignorance, attribution
Feedback Survey • Respondent information (not used for report) • HASDM Project Comments • Assumptions • Consistency of methods • Appropriateness of tests (complete, independent) • Meaningfulness of results • Traceability of conclusions • Additional thoughts
Feedback Survey • Technical Review Comments • Success of review • Prior expectations • Difference between expectations and results • Value and effectiveness of process • Recommendations to improve • Additional thoughts
Review Outcome • HASDM evaluation - too much to present - see paper for examples
Lessons Learned • Model development • Specific criteria need to be established to enable objective evaluations • Options should be investigated and documented first (approach, baseline, parameterization, validations) • Design tests that are independent
Lessons Learned • Review process • Coordination of review needs to be improved • Participants were not sure who briefs, who pays, etc. • Insufficient time for review • Lack of formalism in process • No mechanisms for tracking resolution of criticism • After USSPACECOM demise, no accountability to process
Recommendations - HASDM • E10.7 was not ready for implementation • The progress of the DCA portion of HASDM merited further evaluation • Establish evaluation criteria • Investigate other options • Conduct/Improve tests for performance evaluation and operational suitability • Perform cost/benefit analysis • Distribute as much data as possible to the research community to improve the science and allow for other ideas to mature
Recommendations - Technical Review • Process should be applied new models or significant modification • Review needs to become requirement for operational implementation • Organization needs to be assigned responsibility • Needs authority, independence, and impartiality • Need mechanisms for tracking resolution
Summary and Conclusions • Review process used only once for HASDM • Identified criticisms of execution in model development and highlighted areas of concern • Serves as example for future reviews • Technical review is necessary to gain community buy-in and identify loose ends • Data and technical info should be made available to industry and academia • Overcome institutional inertia obstructing team work, cooperation, and interoperability
