CONDUIT Working Group Meeting
29 May 2003

Participants:

Meeting Introductions and Agenda

Background Materials

Meeting Goals:

• define new datasets for CONDUIT
• discuss possibility of combining advisory structure of CONDUIT and leveraging from CRAFT for reporting to the USWRP Interagency Working Group
• discuss a broad vision of coordinating local model output with others in the community; e.g., real time modeling, data assimilation

CONDUIT:

The current status of CONDUIT data distribution is the most successful report since the inception of the project. This is primarily due to the new LDM version 6 that has been installed at the NWSTG and the relay sites. Steve Chiswell’s slides include statistics indicating the decreased latency changes since the upgrade to LDM6. This change positions CONDUIT for new and additional datasets to be added to the data stream.

• volume is 25.4 GB/day
• average delivery time to top tiers of 20 seconds
• 16 sites participating
• data currently sent from NWSTG to top level relay machines at:
  • NSF
  • Wisconsin
  • Illinois

Current CONDUIT datasets are listed at this location.

Group discussions covered broad issues:

• possibly leveraging from the CRAFT project, including the lessons learned which could be advantageous for the CONDUIT project
• should CONDUIT remain a test bed for distribution and use of high volume datasets
• CONDUIT should provide an opportunity for interested community members to identify and expand the datasets, perhaps through a survey
• datasets should be diverse to serve a broad community, e.g., ensembles
• should CONDUIT broaden datasets to include datasets from other sources

Kelvin Droegemeier, new Chair of the CONDUIT working group, provided a brief overview of the CRAFT project, and made some suggestions on how CONDUIT might leverage what CRAFT learned over the past five years.

• CRAFT formed the nucleus of planning and testing for the Level II data distribution, which has ultimately been adopted by the NWS for distribution of the data

• Action: Bob Gall and Kelvin Droegemeier should provide a paragraph on the charter of a new committee, (morphed group of CONDUIT and CRAFT)

A presentation by Mohan Ramamurthy on local modeling performed at various institutions throughout the U.S., provided a glimpse of what could be done if there was coordination among the institutions to aggregate local models into what could be portrayed as a “national instrument.”

Alan Hall, NCDC, provided a short presentation on NOMADS (see slides, created by Glenn Rutledge, NOMADS PI). NCDC is archiving the NOAAPort data by WMO headers. They are looking for a backup that has control block headers on the data for AWIPS use. Coordination is needed between the CONDUIT project and NOMADS to avoid duplication of efforts and continuity. With the continued interest and involvement of Alan Hall, NCDC, Jim Steenburgh, University of Utah, member of the NOMADS scientific steering committee, we should be able to stay apprised of the activities associated with NOMADS.

Several options for new datasets are available from NCEP to be included in the CONDUIT data feed. There was a review of what datasets are currently provided and used, versus some newly available datasets that could be useful to the broader community. Following a lot of discussion about datasets that could serve the majority of users, the following datasets were identified, with the caveat that ongoing online discussion could continue as other datasets are identified and available.
