Administrative Items

New committee members introduced themselves briefly, and commented on the morning new member orientation session. Comments on the orientation were favorable.

Status Reports

Brief discussion of the staff status reports:

ACADIS:
There is coordination between ACADIS and DataOne Data Management Plan to NSF for NSF proposals.
NSF is mentioning ACADIS data management plan as an example of how to construct a plan. Rosetta is part of this, and a demo is scheduled later during the meetings..

Community:
It was suggested that UPC make product-specific pages using Twitter and other media. There should be a tweet for every bug fix.

Action 1: Linda will work with Ginger and Tina to make a reservation for Center Green for the next summer UserComm workshop. The dates mentioned would be mid-July to late-July of 2015. Plan on 100 people again.

Workshop:
There was a question of how current enrollment numbers compare to previous years, and what the brekdown of registrants from universities/industry/government, etc.

Outreach:
Tom Whittaker attended a meeting where CF as an international standard especially focusing on standard names was discussed. It is important to continue getting the word out at meetings.

GEMPAK:

• A question of making GEMPAK available via Github was raised. Will this happen?
• Another question related to the idea of binaries being made. This has not been done for any platforms. The reason binaries went away was the number of problems with library mismatches, for which the solution was to have users build from source.
• OpenMotif was the biggest problem. Even now have to have GEMPAK users build OpenMotif to get GEMPAK to work.
• Standard repositories have packages for NetCDF, etc.
• Many of these packages are developed/supported by third parties
• There are some community members who do this already.
• Is a vm distribution an option?
• Usercom need to ascertain whether there is a real need for this in the community
• Is it worth trying to recruit users to contribute builds?
• Gempak 6.7 is out...
• The question of why the decision was made made to keep supporting GEMPAK
• Scott Jacobs responded by saying that NCEP has several other projects that require GEMPAK functionality, at least in the batch mode. GUI programs will be kept going for a while, but NAWIPS programs will be replaced by AWIPS II GUIs
• Another question of maintenance of GRIB tables, to which Scott replied that table maintenance is problemantic, and they are working on possible solutions
  

IDV:

• By request, the IDVsteering committee is spinning up again
• Usercom should be the entity that sends the message out to invite participation in steering committee.
• Steering committee members provide suggestions, server as alpha/beta tester for suggested features, conference calls/webex showing discussing functionality.
  
  Action 2: Call for the IDV Steering Committee to go out from Usercom for participants, starting with list from IDVgroup (Julian Chastang)
  

IDD:

Steve Lazarus is planning on setting up a regional workshop at Florida Institute of Technology. He would like to see UPC create a YouTube video of how to set up the IDD.

International:

• Tom Yoksas said the Africa initiative he's been collaborating on with NCAR will be wrapping up this fall, ending with technology transfer
• John Caron is going to a google conference "geo for good", mostly to network
• Tom Whittaker said that he's involved in a project with Eumetsat to install McV at Eumetcast stations

McIDAS:

• McV and IDV developers continue to have monthly telecons and share resources. Site visit is planned for this fall.

NetCDF:

• NetCDF windows: a lot of folks don't seem to be aware of work. Cygwin supports NetCDF
• Many folks don't seem to be aware of the work done Cygwin supporting NetCDF
• Unidata is providing binaries for windows -- 12 separate builds with all permutations
• The question of how to publicize
  • Focusing on Windows 7
• Is there any talk of NetCDF JavaScript API? Access to OpenDAP and/or netCDF files
  • There is something called DirectWeb Remoting,
  • Usecase: ncview in the browser would be awesome. Some clients are a pain to build/configure

Support: Question

• Question from Rich Signell-Jira is great, but now I don't know what to do when I have something that might be a bug. Am I supposed to post it to Jira as a bug report or enhancement? People in general don't know where to direct questions.
• Comment from Tom Whittaker-There should only be one place to look to track/search for issues
• Kevin Tyle indicated- It isn't clear when/if someone from Unidata will answer mailing list questions
• Russ Rew asked if we should be posting to the mailing list when issues are moved to Jira?

TDS

• At the last UserComm meeting there was discussion about grib naming. John Caron said there had been discussions between TDS/IDV groups taking place. Rich Signell inquired about progress on the Opuls project. The funding has been problematic, according to Caron.
• Dennis Heimbigner indicted that the UPC canan keep committee up to date on spec revisions
• A question about when/why the upgrade to Java 7?
• Eathan Davis siad the end of life for Java 1.6 is "soon"
• Lots of good stuff in Java 7 file support.
• Both NetCDF Java and TDS will update to Java 7, both to be called version 5
• According to Sean Arms, there have been problems with Java3D and Java 7
• John Caron indicated that they are cautiously optimistic about community support for Java3D

CONDUIT Report

Scott Jacobs made a presentation for Becky Cosgrove (slides).

• Move to new NCEP building is complete
• RAP has been implemented to replace RUC, with corresponding CONDUIT changes
• SREF changes are reflected in CONDUIT
• Waiting for hardware refresh to increase LDM queue from 6GB to 20GB, at which point additional model output can be added
• Began testing live feed 10 September 2012 with Unidata (Tom Y)
• Testing planned to be complete in mid-October, when they will transition to new servers
• Question: RAP 13km or 32km first? Need both? (NOAAPort has 13km but only surface fields, not 3D)
• Action 3: Recommend 13km RAP be added, not 32km as previously planned
• Question: NAEFS raw or bias-corrected? Rich Signell says: raw grids, SC agrees.
• Action 4: Recommend NAEFS raw grids be added
• For Hurricane models, there are multiple resolutions available
• Action 5: Russ Schumachermaker recommended asking colleagues which resolution do they want/can handle it?
  Addition of Hurricane data ON HOLD until we get more information from the community
• Note that Pull is available for all of this data, but not automated like IDD delivery
• Question: GFS and Global RTOFS: What does the community need, more specifically?
• No model upgrades planned until fall 2013 after new supercomputers are in place
• Existing products from existing models *can* be added to CONDUIT
• HRRR: Becky asks Usercomm to send official request to her boss (Ben Kyger) requesting access
• Action 6: Draft note to Ben Kyger requesting access to HRRR.

Users Workshop Report

Steven Lazarus provided a brief update on progress on BAMS article, to be submitted November 2012 if possible.

Future: When collecting registration information, ask how they heard about the workshop

Action 7 : UPC to create followup survey approx 6 months after workshop:

• how have your data usage habits changed?
• use of USB stick?

DeSouza Award

Blue Sky Session

Tom Whittaker described this session and why it is needed. The Usercomm should discuss items/issues of importance to them as they plan for the future for their classes/labs. Unidata has global footprint. UPC should look seriously at "cloud" type computing, allowing use of minimally powerful devices.

Jennifer Collins said that there are not many Unidata users at her institution. Regional workshops would be good for getting other disciplines involved.

Mike Baldwin made the point that students are running Mac's not RedHat. They use their own PC's from home.

Marty Baxter is in favor of tablet-style computing, need new interfaces for IDV that use touch gestures
(Jeff/Sean and Mike Schmidt are working on a Kiosk mode coming soon) Marty said he would be willing to serve on the IDV steering committee!

Steve Lazarus said there's an issue with using IDV in the classroom -- could be less clunky, a simplified version of the UI

Stefan Cecelski - would like to have an option just to look at the data -- quick action when you don't need to modify the data

Anne Case Hanks- Likes the idea of a lite version of IDV on mobile device. Could be images, but want to be able to composite data sets, display on globe, etc.

Sam Ng would like a Mobile way to get data to students. Switching to IDV as a start.

Rich Signell said it would be nice to have IDV functionality broken out as components that could be reassembled into different workflows. Python might be a good glue for the logic represented by IDV workflows. (Mike Baldwin added, when you work in a web services environment, the choice of a development environment becomes less important)

Kevin Tyle - Emphasis on collaboration in IDV --

Russ Schumacher - Provide "Nate Silver style" probabilistic predictions built from ensemble weather predictions

Tom Whittaker - How do we get more value from our data via novel visualizaitions

Marty Baxter - enhance Unidata outreach efforts to communicate what is already available within atmos community and beyond. TED talk style demonstrations of what you can do and how to do it. Unidata can help with curriculum development, merging computer science concepts with the meteorological work. Tools to make it easier to evaluate forecasts?

Bart Geerts said IDV good for querying 4-D structure, I like to use it for vertical structure. These transects are not easy to combine, overlay. SkewTs don't provide enough detail, would like to see that improved. Would also like to see notes within the interface itself. (GeoPod?)

Miscellaneous Topics

Site contacts:

• Kevin Tyle said that we need more structure to the contact effort?
• Steven Lazarus: We have some history from previous iterations
• Tom Whittaker: : Tool that Jen put together is useful; is it too hard to keep up to date?
• Kevin Tyle said It is important to think about what we want to ask folks
  • - how has IT support landscape changed?
• Tom Whittaker said that When Gary Lackmann was chair, each contact was a mini survey. Is that too much?
• Anne Case Hanks - Usercom can decide what to focus on prior to each contact episode
