    Irish Chronicles Document Links Between Volcanoes and Weather

    A study of over 40,000 written entries in Irish Annals and ice core measurements shows a strong correlation between the occurrence of volcanic eruptions and extreme cold weather in Ireland over a 1200 year period. Data analyzed in this study cover the period from 431 to 1649, during which time up to 48 volcanic eruptions are identified in Greenland ice core records through deposition of volcanic sulfate in annual layers of ice. You can find the study (open access), published on 6 June 2013 in IOP Publishing's journal Environmental Research Letters, at http://iopscience.iop.org/1748-9326/8/2/024035/article.

    EF-5 Tornado in El Reno, Oklahoma Widest Ever Recorded in US

    The EF-5 tornado that hit El Reno, Oklahoma on May 31st was the widest ever recorded in the US, according to the National Weather Service in Norman Oklahoma. The tornado, which remained on the ground for 40 minutes and reached 2.6 miles across (4.2 km), took the lives of 18 people including storm chasers Tim Samaras, Paul Samaras and Carl Young.

    Atmospheric CO2 Level Tops 400 ppm

    During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well. The level of atmospheric greenhouse gases continues to increase, now over 120 ppm since the Industrial Revolution began. For more on the Keeling Curve, see http://keelingcurve.ucsd.edu/.

You can find me flying on the C-130 aircraft during VOCALS at all hours of the day and night! I will be catching droplets from clouds off the coast of Chile and seeing what's inside them. It's not just water…cloud droplets form on small particles in the atmosphere. These particles are the result of both natural processes, like salt from the breaking waves over the ocean, and human activity, like driving in your car. We're trying to learn which of these particles form cloud droplets and ice in the atmosphere, and how that affects cloud cover, rain and snow, and global climate change.

I got into this business because I was good at science and wanted to be an astronaut. For that, I needed a graduate degree as well as some flying experience! So I went to the University of Washington, where they had a research aircraft and I could do both. In my first research project, I was sampling stratus clouds of the coast of California. Now I am sampling them off the coast of Chile. In the meantime, I've been on thirty different projects flying all over the world including Australia, Bahrain, Costa Rica, and India. Not exactly an astronaut (NASA said my vision wasn't good enough), but this life is almost as interesting and probably more rewarding.

For ten years, I was a scientist for the National Center for Atmospheric Research in Colorado, and now I've landed back in the Pacific Northwest at Oregon State University. My husband and I grow grapes for wine, and when not traveling I enjoy horseback riding, gardening, and collecting antique books.
