Dessler, Jimenez, Klein, and Nenes Receive 2012 Atmospheric Sciences Ascent Awards: Response

I am honored and humbled to receive the 2012 Ascent Award from AGU. Not so long ago, I remember being amazed by the energy, excitement, and rigor that I witnessed at my first AGU Fall Meeting in 1999. I have been lucky to participate in a period of rapid learning about the composition and sources of aerosols at a time when science is increasingly collaborative. There is still much to be learned in this and related fields to have confidence in our predictions of climate forcing and air quality, and I look forward to many more collaborations and AGU Fall Meetings during the second half of my career.
