CS Staff to Present Climate, Weather Research at Dec. 12-16 AGU Meeting

When approximately 24,000 attendees convene in San Francisco for the 2016 American Geophysical Union’s Fall Meeting, staff from NERSC and the Computational Research Division will be among them, giving invited talks, presenting papers and showing posters. Now in its 49^th year, the Fall Meeting is the largest Earth and space science meeting in the world. The meeting will be held Dec. 12-16 in the Moscone Center.

With more than 1,700 sessions, the meeting offers a mix of more than 20,000 oral and poster presentations, a broad range of keynote lectures, and various formal and informal networking opportunities. Here’s a list of activities Computing Sciences staff will be participating in:
