Unidata celebrated its 25th anniversary on 15-16 October with a rare gathering of staff, founders, partners, and collaborators from around the country. Attendees celebrated the program's accomplishments and looked ahead to the future.

The National Center for Atmospheric Research (NCAR) is partnering with the Boulder Public Library to present a series of public talks and a new exhibit to mark the research organization's 50th anniversary this year.

A team led by NCAR's Jim Smith has found that aminium salts make up as much as half of the mass of newly formed particles in places as diverse as Atlanta, Mexico City, northeast Colorado, and Finland.

Communications has prepared this guide to help staff get the word out to colleagues, the media, and the public about your activities at NCAR and UCAR. Your feedback on the guide is welcome.
