Two Postdoctoral Fellow Positions Available

Two postdoctoral fellow positions available in the Prather group to study the impact of aerosols on climate. Three upcoming projects in California this coming year will investigate and characterize atmospheric aerosols and their impact on clouds and regional climate. One study will focus on determining how soot or black carbon is impacting our climate. A person with a strong radiative forcing or optics background would be ideally suited to this project. Two other projects will focus on atmospheric and precipitation studies.

Kerri Pratt is defending her PhD on 6/29/09

Open to the public, Kerri Pratth is presenting some of her research from her dissertation on Monday, 6/29/09 at 1:00pm in the Natural Sciences Building room 1205.

What is our current understanding of aerosols impact on climate change?

Professor Prather has a viewpoint in ChemSusChem  discussing what we know about how aerosols change climate and how this knowledge is changing as analytical techniques improve.

Maggie Yandell and Brandon Heilman graduated!

Our two senior undergraduates just graduated! In addition to graduation, Maggie received the Urey Award for academic excellence in chemistry!

Maggie will continue her studies at Berkeley and Brandon his at Santa Barbara. Best of luck them in their future!

Emissions from the Los Angeles/Long Beach ports affect San Diego

A recent paper published in Environmental Science & Technology attributes an increase of particulate matter during regional transport events in San Diego from the ports of Los Angeles and Long Beach. This particulate matter is mainly soot, vanadium, iron, and nickel, sulfate, and nitrate, from ships, refinaries, and port traffic.

Our Lab Directly Detects Biological Particles in High-Altitude Ice Clouds for the First Time

A paper published in Nature Geoscience "In situ detection of biological particles in cloud ice-crystals," shows results from the Aircraft-ATOFMS used to chemically identify the chemistry of ice-cloud crystals in high altitude clouds. This is the first direct detection of biological particles, internally mixed with dust, in ice clouds.

Professor Kim Prather and grad student Melanie Zauscher receive sustainability awards

During UCSD's earth week this year, Professor Kim Prather received the Faculty Sustainability Award and Melanie Zauscher received the Graduate Student Sustainability Award. For more information and to see other other recipients, go to at This Week @ UCSD. Last year, Meagan Moore won the Graduate Student Sustainability Award.

Is Air Pollution Reducing California's Water Supply?

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.
