    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/.

    Massive Tornado Outbreak on Tornado Alley

    The week of May 19 brings dozens of tornadoes to Tornado Alley in the states of Oklahoma, Kansas, Iowa, Illinois and Missouri. On May 20th, a massive tornado struck Moore, Oklahoma, devastating communities - destroying over 100 homes and hitting two elementary schools and a hospital - with many casualties and deaths. Our thoughts are with our friends and colleagues suffering from these storms. For more on the May 20th storms, see the NOAA Storm Prediction Center Storm Report.

    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    A bill has been introduced in the Kansas legislature this week that would prohibit the promotion of sustainability. Here is a link to the one-page bill: http://www.kslegislature.org/li/b2013_14/measures/documents/hb2366_00_0000.pdf. See report on Bloomberg News.

Dr. Dara Salcedo

I am originally from Mexico City were I grew up and eventually got my Bachelor's degree in Chemistry. When I started college, I had many questions about molecules, reactions, colors, substances, and I thought that everything was going to be answered in my classes. Soon, I realized that every time a question was answered, three or four new questions arose! By the time I got my degree, I knew that doing science to answer questions is a never ending story, but it is fun, so I went to Cambridge, MA to get my PhD. I chose the field of Atmospheric Chemistry because it is about applying Chemistry to understand the environment. Also, I like to think that the research I do will be useful for policy makers to generate new laws that will protect our health and environment. Now, I live in Cuernavaca, a city south from Mexico City, which is called "the city of the eternal spring" because it has a very mild weather and you can always find a tree blooming!

During MILAGRO, I will be at T0 measuring particles. The objective is to learn about their chemical and physical properties and to deduce their history (where they were emitted and how they were transformed once in the atmosphere). I could not do the latter without the help of other colleagues measuring gases, temperature, wind, etc. That is what it is important about the MILAGRO project: every research group is doing a different measurement; when all the measurements are put together will be able to understand air pollution better (like pieces of a puzzle that form a landscape when put together).

When I am not doing science, I enjoy to be at home, cooking, hiking and going to the movies. I also like traveling with my husband and we use every opportunity we have. This photo was taken last year in Sidney, Australia. Next April, we are going to visit some caves in Central Mexico (a well deserved trip after all the hard work in March during MILAGRO).
