## Regular Technical Algorithm/Performance Oriented Meetings

- SE IPT chairs VIIRS (weekly) and CrIS/ATMS (bi-weekly) Algorithm Performance meetings
- Discuss both hardware and software topics of importance to algorithm and product performance
- Detailed technical discussions
- Wide attendance
- POCs:  Phil Moffa for CrIS, ATMS, CMIS; Debra Olejniczak for VIIRS
- P/L & SE IPTs organize weekly OMPS technical telecons
- Similar scope to above VIIRS, CrIS/ATMS meetings
- POCs: Raymond Crew & Maria Caponi

***This list is not meant to be exhaustive.  ***

## Regular Technical Algorithm/Performance Oriented Meetings, cont’d

- Regular Operational Algorithm Team (OAT) meetings are held
- The OATs are advisors to the IPO
- SSPR team utilizes OATs for recommendations, “peer” reviews, and possible assistance on ongoing algorithm tasks
- All OATs meet nominally every 6 months at a joint “NOAT” meeting
- Discuss both hardware and software topics of importance to algorithm and product performance
- Detailed technical discussions
- Wide attendance includes OATs, IPO, SSPR team, multiple IPTs
- OATs meetings are one of the best ways to flow external science community comments and recommendations to SSPR team
- POCs: Jim Duda, IPO & Pam Emch, NGST

## There are Algorithm (Splinter) Sessions at Regular Program Meetings

- Algorithm Splinter at PMRs
- Every month; nominally 2 hrs. long
- Excellent opportunity for cross-IPT discussions at a management level
- NGST/RC PMR attendees are normally IPT leads, not necessarily technical task executors
- POC: Emch
- Algorithm Session at SEI F2F meetings
- Approx. every 2 months; length determined by topics
- Attendees are primarily SEI, both technical and management
- Good opportunity to have mid-level technical discussions regarding SEI tasks & issues
- Possible to discuss cross-IPT topics based on attendees
- Very detailed discussions may require separate focus meetings
- POC: Emch

***The topics and length of these sessions will be on an as-needed basis. ***

## There are Algorithm (Splinter) Sessions at Regular Program Meetings, cont’d

- Algorithm Session at IDPS F2F meetings
- Every 6 weeks; length determined by topics
- Attendees are primarily IDPS, both technical and management
- Emch to provide top-level alg status (PMR status); remaining portion of session led by SE
- Good opportunity to have mid-level technical discussions regarding joint IDPS/SE tasks & issues with access to the broader IDPS team
- Should segue to include ST&E and O&S
- Very detailed discussions may require separate focus meetings
- POC: TBD within SE IPT

***The topics and length of these sessions will be on an as-needed basis. ***
