Scripps Institution of Oceanography Explorations e-magazine has an article about our field study this past winter that looked at how the chemistry of air pollution may affect precipitation in California.

Kerri's 2009 NOAA Climate and Global Change Postdoctoral Fellowship is for her research with Dr. Dan Cziczo and Dr. Jennifer Comstock at PNNL. Her proposal title is: "Investigation of cloud ice nucleation by atmospheric aerosols: Field measurements & parameterization"

Maggie received both the 2009 National Defense Science and Engineering Graduate Fellowship and the National Science Foundation Graduate Research Fellowship for her chemistry PhD research at UC-Berkeley.

Andy's 2009 DOE Global Change Education Program Graduate Research Environmental Fellowship fellowship is for research with Professor Kim Prather and Dr. Rahul Zaveri (PNNL); His proposal title is: "Integration of field measurements of chemical, physical, and optical properties of single particles into a particle resolved climate model" (for modeling his PACDEX data)

A recently published paper in Analytical Chemistry describes our newest ATOFMS, modified to work in research aircraft. Besides being a smaller size and having a decreased power consumption, the A-ATOFMS also has an increase mass resolution and size transmission. For more details check out the article.

She explains how fires produce soot particles, which enhance climate change and supress rain. Check out the audio interview on The Science Show on ABC National Radio.

Maggie Yandell was among 21 undergraduate students that received the 2008 Dean's Undergraduate Awards for Excellence which recognizes undergraduate students who have demonstrated academic excellence and promise as researchers. Maggie has been in our lab for 4 years and is currently deciding which graduate program she will attend next year.

We are participating in a field study at Sugar Pine Dam to determine how particulate matter affects precipation in California. We have a nozzle ATOFMS, an ultrafine ATOFMS, a CCN counter, SMPS, APS, gas phase instruments, aethelometer, PILS/IC, and a metereological station collecting data for about 2 weeks. Project is being funded by the California Energy Comission.

A few of us got interviewed for channel 10 news

The article "Effect of chemical mixing state on the hygroscopicity and cloud nucleation properties of calcium mineral dust particles" was published January 28, 2009 in Atmospheric Chemistry and Physics Discussions. It was co-authored by our group and our collaborators at Scripps Institution of Oceanography and Colorado State University.
