    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. For more information on the tornado, visit http://ow.ly/i/2hfDG.

    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/.

The Center of Operations

The Operations Center is at the center of large field experiments like VOCALS. Here, the scientists plan their aircraft missions. Here is where these plans are passed from the minds of the scientists to the pilots, ground crew and support staff that turn them into reality. Next time you fly on a commercial airliner think about all the people working at the airport and on the plane that have been involved in flying you to your destination. It's a big operation!

The Operations Center is also where discoveries are made. The scientific data from all the various missions are collected here and analyzed by the many scientists involved. Together the scientists form a large human computer whose goal is to make sense of all the data. Only through careful analysis of the data is it clear what these discoveries actually are. It is very difficult to know exactly what new discoveries will be made - in fact, the most exciting thing about discovery is that we don't know what surprises are around the corner.

In the photograph you can everyone here listening to a mission briefing whereby preliminary results from a given flight are presented for the first time to the scientists. The Operations Center is an exciting place to be because there is so much going on, and so much new information to try to make sense of.
