The July 9-15 NCAR Undergraduate Leadership Workshop in Boulder gives upper-division college students a chance to explore careers in the atmospheric sciences; meet with NCAR scientists, grad students, and private-sector professionals; and connect with peers from around the nation. Areas of scientific focus include weather research, forecasting, climate modeling, solar dynamics, and societal impacts of severe weather and of climate change. Professional development includes advice on résumés and elevator speeches.

Each university or college department may nominate one student for the workshop. NCAR|UCAR provides lodging and meals, and the department provides student travel to Boulder, Colorado. Additional travel support may be provided to Minority Serving Institutions. The nomination and application deadline is April 15. For additional details, see Undergraduate Leadership Workshop.

Evaluations of the program, now in its 15th year, have found multiple long-term benefits. In addition to sharing this call for nominations with colleagues, we invite you to share information on successful outcomes of the workshop via this early online release from the Bulletin of the American Meteorological Society, “Long-term Impacts of a Career Development Workshop for Undergraduates.”

Apr. 14, 2017

Registration remains open for the final session in an NCAR/CISL series of workshops on Modern Fortran. The last workshop in the series is scheduled for Thursday, April 13. Dan Nagle, CISL Consulting Services Group software engineer and a member of the U.S.  Fortran Standards Technical Committee, will provide the training at the NCAR Mesa Lab in Boulder (VisLab ML4).

  • Parallel Fortran - April 13: Coarrays and related topics, including memory management and communications schemes (for example, synchronization vs. events).

The workshop begins at 9 a.m. and will end by 4 p.m. with an hour break at noon.

The /glade/scratch file space for the Yellowstone, Geyser, and Caldera systems will point to the new, larger GLADE scratch system following a maintenance downtime that is scheduled for Tuesday, April 11. The old scratch space will be available in read-only mode as /glade/scratch_old after that date until June 1.

Yellowstone users who have not already done so should move their scratch files to /glade/scratch_cheyenne. After April 11, that new space will become /glade/scratch.

On June 1, /glade/scratch_old will be removed from all systems. The disk space will be repurposed for use as project space. Please see GLADE File Spaces for more information.

The Yellowstone, Cheyenne, Geyser, and Caldera clusters and the GLADE file system will be unavailable from 8 a.m. to 5 p.m. MDT on Tuesday, April 11, to allow CISL staff to upgrade the GLADE file system.  

A system reservation will be put in place on batch jobs at 12 noon on Monday, April 10.  After the system reservation is in place, jobs submitted with specified job times that overlap the reservation period will remain on hold until the system is restored to service. Running jobs that have not finished when maintenance begins will be killed and will need to be resubmitted after the maintenance period.

We apologize for any inconvenience this might cause. Users will be informed via the CISL Notifier service when the systems are returned to production.

NCL 6.4.0 is now the default version on the Yellowstone and Cheyenne systems.

To access this version run module load ncl on your command line after logging in.  Load previous versions by specifying the version number (for example, module load ncl/6.3.0).

Here are some of the highlights of this release:

  • Over 100 new functions (crop, heat stress, extreme value statistics, bootstrap, evapotranspiration, simple_legend)

  • Many improvements and fixes to HDF5, NetCDF4, and GRIB readers

  • Labelbars can be generated with triangle ends

  • Block style comments allowed

  • Numerous new graphical resources (including the overhaul of color resources to allow RGB/A values)

  • Many new example pages and scripts

  • MediumRes map database made the default for certain map outline and fill settings

  • Bug fixes

  • A new version (1.1) of the NCL User Guide (NUG) accompanies this release:
    http://www.ncl.ucar.edu/Document/Manuals/NCL_User_Guide/

For complete details, see What's new in the current release.

Registration remains open for the NCAR/CISL series of one-day workshops on Modern Fortran. The next workshop is scheduled for Thursday, April 6. Dan Nagle, CISL Consulting Services Group software engineer and a member of the U.S.  Fortran Standards Technical Committee, will provide the training at the NCAR Mesa Lab in Boulder (VisLab ML4). Each session will be webcast.

Workshops begin at 9 a.m. and end by 4 p.m. with an hour break at noon.

  • Object-Oriented Fortran - April 6: Making user-defined types, information hiding, generic names, operator and assignment overloading, and inheritance.

  • Parallel Fortran - April 13: Coarrays and related topics, including memory management and communications schemes (for example, synchronization vs. events).

No Scheduled Downtime: Yellowstone, Cheyenne, Geyser_Caldera, HPSS, GLADE

Apr. 3, 2017

The new-15 PB GLADE scratch file system is now mounted and accessible on Yellowstone as /glade/scratch_cheyenne so Yellowstone users can begin moving scratch files that they need to keep to the larger system also used by Cheyenne.

As announced previously in the Daily Bulletin, /glade/scratch_cheyenne will be available for approximately two weeks. Users are strongly encouraged to begin transferring their scratch data to the new space as soon as possible.

After an April 11 outage for Yellowstone, Geyser, and Caldera, the /glade/scratch on those systems will point to Cheyenne’s new, larger scratch file system and the old scratch space will be available as /glade/scratch_old in read-only mode.  

On June 1, /glade/scratch_old will be removed from all systems. The disk space will be repurposed for use as project space. Please see GLADE File Spaces for more information.

NCAR researchers and computational scientists are encouraged to submit requests for NCAR Strategic Capability (NSC) projects to be run on the new 5.34-petaflops Cheyenne system.

The deadline for NSC submissions is March 30. NSC allocations target large-scale projects lasting one year to a few years that align with NCAR’s scientific priorities and strategic plans.

For more information, see the 2017 Call for Proposals from NCAR Researchers for NSC Resources.
