    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.
The scientific results of the VOCALS field campaign are based on analysis of observations made by instruments located on ships, aircraft, and land. This map shows the paths followed by ships and planes over the Southeast Pacific and the observation stations along the coasts of Chile and Peru.

What are the results of VOCALS?

Long after the VOCALS campaign is completed, the scientists’ work will continue. They must process, review, and study the data to determine what has been learned. Many model runs will be made and analyzed. Eventually, they will publish their discoveries in scientific journals and give oral presentations at conferences.

VOCALS will allow an unprecedented examination over an entire month of how variability in ocean currents, ocean upwelling, marine winds, and air pollution will impact the chemical and physical properties of the lower atmosphere, the clouds, and the amount of precipitation found there. The climate characteristics of the SEP are further complicated by the close proximity of the Andes Mountain range which forms a barrier to westerly winds and the transport of moisture.

It is expected that measurements obtained by VOCALS will have a broad impact upon current knowledge in the fields of atmospheric science and oceanography. The data generated in the field will stimulate the development of a broad range of numerical process models exploring the atmosphere. They could also help to accelerate the improvement of regional and global climate. VOCALS could ultimately lead to much better predictions of future climate. Climate prediction is increasingly important to communities around the world that are vulnerable to the impacts of climate change, such as sea level rise, heat waves, less reliable precipitation, and changes in growing seasons.
