VORTEX-SE 2017 Field Campaign Begins
ATDD is participating in the second VORTEX-SE Field Campaign March – April 2017. Temple Lee, Michael Buban and Ed Dumas have the lead on the Intensive Operating Periods (IOP). During this time ATDD will have teams releasing radiosondes, manning a tethered balloon and obtaining vertical profiles using small unmanned aircraft that will be used to measure low level temperature and relative humidity . All of these measurements and measurements from other participating scientists will be used as input into a numerical model to better understand the influence of terrain, land surface, and boundary layer heterogeneity on tornadic storm development.
More information about this year’s field campaign can be found in a couple of articles with links below by Christina Edwards of WHNT19 news in Huntsville, Alabama.

NOAA/ATDD will be operating two small unmanned aircraft systems (sUAS) in the Verifications of Origins of Rotation in Tornadoes Experiment in the South East (VORTEX-SE) from March 8, 2017 through May 8, 2017. During this period, ATDD will operate its sUAS systems at altitudes of up to 1200 feet above ground level above property outlined in the blue area in the map of northern Alabama near the city of Huntsville. This area is referred to as the storm damage assessment area (SDAA). During this period the sUAS will be in technical compliance with PII information collected in accordance to the presidential memorandum “Promoting Economic Competitiveness While Safeguarding Privacy, Civil Rights, and Civil Liberties in Domestic Use of Unmanned Aircraft Systems.”
UTK-ATDD sign Memorandum of Agreement
On February 15, 2017, ATDD and the University of Tennessee-Knoxville (UTK) signed a Memorandum of Agreement (MOA) to advance collaborative research in atmospheric sciences. The MOA was signed in the ATDD auditorium by Dr. Taylor Eighmy, Vice Chancellor for Research & Engagement at UTK, and Dr. Bruce Baker, ATDD Director.
The agreement will facilitate joint efforts between UTK faculty and ATDD scientists to advance understanding of air pollution, atmospheric transport processes, and weather on a regional and national level. Additionally, the MOA will lead to educational opportunities for undergraduate and graduate students at UTK to participate in atmospheric science research investigations alongside NOAA scientists and engineers.

- The Sensitivity of Convection Initiation to Surface Heterogeneities during VORTEX-SE” by Michael Buban.
- “The WMO Solid Precipitation Intercomparison and the determination of universal wind speed corrections” by John Kochendorfer.
- “Use of a Small Unmanned Aircraft System in VORTEX-SE 2016” by Ed Dumas.
- “A Re-evaluation of Particle Dry Deposition over Forested Landscapes” by Rick Saylor.
- “A Comparison of Two Chemical Mechanisms Using Data from the Southern Oxidant and Aerosol Study”, Student Poster Session, by Sheridan Green (2017 NOAA Hollings Scholar Intern) and Rick Saylor.

LaToya Myles selected to receive
2016 Technology All-Stars Award
Congratulations to Dr. LaToya Myles for being selected to receive the 2016 Technology All-Stars Award at the upcoming Technological Recognition Luncheon during the 21st Women of Color STEM Conference in Detroit, MI on October 14, 2016.
The Women of Color STEM conference has been recognizing the achievement of women in science, technology, engineering, and math (STEM) careers for more than 20 years. The awards have earned widespread praise for offering unique opportunities for women to parlay their career successes into gains for themselves and the STEM community as a whole.
Dr. Myles has worked actively as an advocate for STEM and continuously works to create a pipeline for under-represented students to pursue careers in atmospheric science, environmental research, and other disciplines. She has mentored numerous undergraduate and graduate students through formal programs sponsored by NOAA, the Howard Hughes Medical Institute, and the American Geophysical Union. As a mentor, she provides students with professional development and research opportunities in addition to their academic training and serves as a stellar example of professional scientific achievement for traditionally under-represented groups. She is also actively involved in K-12 outreach and frequently speaks to students about career exploration in science and technology.
2016 NOAA Hollings Scholars at ATDD
ATDD scientists hosted three student interns from the 2016-2017 NOAA Hollings Scholar class during the summer of 2016. Kathryn Wheeler and Sheridan Green worked with Dr. Rick Saylor doing research with the Atmospheric Chemistry and Canopy Exchange Simulation System (ACCESS) exploring biogenic hydrocarbon chemistry in different forest types and environmental conditions. Russell Krueger worked with Dr. Tilden Meyers evaluating different soil moisture and temperature probes. The three students spent a total of nine weeks at ATDD and then presented their research results at the end of the internship at NOAA headquarters in Silver Spring, MD.
The NOAA Ernest F. Hollings scholarship program is designed to increase public understanding and support for stewardship of the ocean and atmosphere and improve environmental literacy and recruit and prepare students for public service careers with NOAA and other natural resource and science agencies at the federal, state and local levels of government. For more information, visit the NOAA Hollings Scholars program page.
Kathryn Wheeler is a senior in Environmental Science at the University of Delaware. Her research at ATDD explored how daytime within canopy biogenic hydrocarbon chemistry can be better represented in large-scale air quality models.
Sheridan Green is a senior in Astrophysics at the University of North Carolina at Chapel Hill. His research involved the comparison of two gas-phase chemical mechanisms using data from an intensive field measurement campaign in Alabama during the summer of 2013. Both students will present their research results in January 2017 as part of the Student Conference at the American Meteorological Society annual meeting in Seattle, WA.
Russell Krueger, a senior at Gustavus Adolphus College in St. Peter, MN, characterized and evaluated several new soil moisture and temperature probes. Several probe types were compared in a soil testbed in which gravimetric samples were obtained on a daily basis. Comparisons were made with existing technology and calibrations were performed to evaluate overall biases and uncertainties of the instruments.
