8 March 15, PAMS Mini-Conference8 ANSI/ANS-3.11 n DMCC and NUMUG joint venture n Initiated in June 1996 n Issued February 16, 2000 n ANS best selling standard ( ) n Stan Marsh (SCE) and Carl Mazzola (Shaw Environmental) co-chairs n Working Group of 30 Subject Matter Experts

9 March 15, PAMS Mini-Conference9 ANSI/ANS-3.11 n Faced a December 2005 sunset n Needed reaffirmation, revision or withdrawn n Questionnaire in 2002 showed strong support for revision (advances in in situ and remote sensing) n Working group approved preparation of a revision in February 2003 n Revised standard approved by ANSI in December Available in March 2006

10 March 15, PAMS Mini-Conference10 ANSI/ANS-3.11 MAJOR REVISIONS n Added sensor accuracy and stability class definitions n Made supplemental measurements discussion more generic n Revised specifications for winds, solar and net radiation, and barometric pressure n New method for accuracy calculations

11 March 15, PAMS Mini-Conference11 ANSI/ANS-3.11 MAJOR REVISIONS n Required calibrations to be part of a Quality Assurance program n Added calibration requirements n Made numerous editorial and clarity revisions

12 March 15, PAMS Mini-Conference12 METEOROLOGICAL APPLICATIONS STANDARD DEVELOPMENT n ANSI/ANS-3.11 WG meeting in January 2004: Pursue development of additional standards related to application of meteorological data n Carl Mazzola and Doyle Pittman selected as co-chairs in March 2004 n PINS for ANSI/ANS-2.15, -2.16, and sent to NFSC in July 2004 for comment n ANSI/ANS needed for real-time transport and dispersion modeling

13 March 15, PAMS Mini-Conference13 METEOROLOGICAL APPLICATIONS STANDARD DEVELOPMENT n 20-member WG assembled: September 2004 n ANSI/ANS-2.15 WG kickoff meeting: November 2004 n All PINS have been approved n First draft of ANSI/ANS-2.15 scheduled for June 2006 n Other three standards will follow n Need more SMEs for ANSI/ANS-2.21
