Upgrading the Rutgers Weather Center to Meet Today’s Needs
Steven G. Decker,
Rutgers University,
New Brunswick,
NJ
Funds received from a 2008 Unidata Equipment Award were used
to purchase two Dell PowerEdge servers containing Intel Xeon E5420 quad-core
processors along with a 4 TB RAID array and miscellaneous supporting equipment.
This equipment was used to upgrade the
"Rutgers Weather Center," a term that encompasses a website as well as the computing environment in which
meteorology majors learn to analyze weather systems and make forecasts. One
server is used to run LDM, while the other server (the “synoptic” server) hosts
the
Rutgers
Weather
Center
website (http://synoptic.envsci.rutgers.edu/site/),
generates imagery for display on the website, and is the primary machine on
which students run GEMPAK tools as part of classroom utilities.
Senior-level courses in weather analysis and forecasting make
extensive use of GEMPAK tools, both at the command line (e.g., sfmap), and
through GUIs (e.g., GARP and NSHARP). The synoptic server has been set up so
that students can log in and run these programs without necessarily being in
the classroom. The new server has proven much more robust at handling numerous
concurrent student sessions, especially when the GUI programs are used. In
addition to computer lab assignments, students are required to generate at
least one unique display (using a GEMPAK tool or the IDV) for use in their
weather discussions. Sometimes, the displays are useful and general enough to
be included as one of the standard products displayed on the
Rutgers
Weather
Center
website. An example of one such display is shown below.

into the

Weather
Center
website. The panels show
(upper left) base reflectivity, (upper right) composite reflectivity, (lower
left) storm-relative velocity, and (lower right) VIL using Level III radar data
from the Fort Dix, NJ (KDIX) WSR-88D. This was the last image created before a
thunderstorm-induced power outage forced a temporary halt to data ingestion and
image generation. |
Unfortunately, the acquisition and set up of the new LDM
server, participation of IT staff in the related training workshops, and
transitioning away from the old LDM server took longer than anticipated.
Therefore, some of the additional datasets envisioned for data ingestion are
not yet being stored. We anticipate the transition to be complete by the end of
the calendar year. A focus for the upcoming academic year will be to incorporate the
GFS ensemble forecasts into classroom discussions.
The upgrades have provided benefits to the broader community
as well. A complete redesign of the
Rutgers
Weather
Center
website was made possible, and weather products are continuously added. The
website is designed to be useful for classroom weather discussions while
providing extra emphasis on
New Jersey
weather, as it is frequently used by members of the public in
New
Jersey
. Google Analytics reports reveal over 1000
unique visitors come to the site each month from places as far away as
India
.
Additionally, the new LDM server serves data downstream to other institutions
and the New Jersey Weather and Climate Network, a monitoring system
administered by the New Jersey State Climatologist in the Department of
Geography at
Rutgers

Unidata: 25 years and counting |
You may already know that 2009 marks Unidata's 25th birthday. We've been celebrating in small steps since the beginning of the calendar year. In fact, the cake pictured in the image highlight above was a focal point of the Users Workshop's evening reception.
Come October we will mark the occasion by holding a day and a half program that will include reminiscences from founding fathers and early community activists, and reflections on what the community created a quarter of a century ago. Not surprisingly, the program has experienced a great many changes since 1984. We've grown the community both in numbers, around 242 individual participants in the early years to over 1500 organizations according to recent data.We've carefully and organically grown in terms of disciplines represented in it as well. In addition, our Network Common Data Form (netCDF), is widely used both nationally and internationally.
Although we think our record speaks for itself, there's always room for improvement. And, we'll be looking for some fun memories to surface during the 15-16 October event, even as we contemplate what the future holds for the program.
We've said it before, but it can't be repeated too often: we are proud of the work we do here at Unidata, and we gratefully acknowledge our partners in each endeavor, our user community.
Additional details will be forthcoming in the weeks ahead.

Newly appointed governing committee members |
We are pleased to welcome new members to our two governing committees, the Policy Committee and the Users Committee.
New on the Policy Committee this year will be Jim Steenburgh, University of Utah and Gary Lackmann, North Carolina State University. David Tarboton will remain on the committee for his second three-year appointment. Both Jim and Gary have served as Users Committee chair, and in that capacity, have attended Policy Committee meetings as the Users Committee representative. All three of these appointments will be able to hit the ground running at the fall meeting.
On the Users Committee, Tom Whittaker (University of Wisconsin), who is presently the Users Committee Technical Representative and chair of the IDV Steering Committee, will assume the role of its chair. New members will be Anne Case Hanks, University of Louisiana-Monroe, Steve Lazarus, Florida Institute of Technology, Patrick Market, University of Missouri-Columbia, and Kevin Tyle, University at Albany, SUNY. Rich Signell, USGS/WHOI and Brent Gordon, NOAA/NCEP will be agency representatives to the committee. As we welcome new members to both committees, we acknowledge the contributions and participation of outgoing members, Rich Clark and Rudy Husar on the Policy Committee and Eugene Cordero and Scott Rochette on the Users Committee.
Both new and outgoing committee members will be in attendance at the fall meeting, being held in conjunction with the 25 Anniversary event 15-16 October in Boulder.
The selection process for new committee members begins with the sending of a call for nominations for both committees from the Policy Committee chair. Appointments are made for a three-year term. Nominations for the Users Committee student member are solicited in the spring. The Committee seeks nominations of Graduate Students who have completed at least one year of study, use Unidata software, and hold a strong interest in the Unidata program.
Once again we remind you that the committees represent everyone in the community. Please contact members of either committee if you have questions you'd like answered or to express your concerns or wishes for future changes. This is the Users Committee contact list, and here is the the list for the Policy Committee.

Training Workshops
Our annual Training Workshops are presently in progress. We will welcome a total 91 participants representing five countries other than the U.S., and 21 educational, 14 government, and four commercial groups. The workshops are a time of great activity in the program center. As well, they provide an excellent opportunity for staff to interact and get acquainted with users who're out there in the trenches using the software and tools that are the core of the Unidata endeavor.
Seminar
Unidata's seminar series is another pathway to integrating our users and the program center. Yesterday we welcomed Sylvie Lamy-Thepaut of the European Center for Medium Weather Forecasts (ECMWF) who made a presentation entitled The challenges of the ECMWF graphics packages. The presentation was webcast live, and that webcast is now available in the webcast archive at rtsp://real.ucar.edu/qtencoder/ecmwf.sdp.
