Carlos Szembek is a 2006 magna cum laude graduate of the University of Massachusetts Lowell where he earned his bachelor's degree in Atmospheric Science. He also earned a master's degree in Climate Dynamics at Yale University in 2010. While at UML Carlos was the president of the student chapter of the American Meteorological Society. He spent two summers taking part in NSF funded research programs in micrometeorology (through Clark Atlanta University; Atlanta, GA) and Arctic
Climate (through Mount Holyoke College; Amherst, MA) on a glacier in Svalbard, Norway. Carlos is currently working at the Westford facility of AECOM. |

Research
Theoretical line shape
calculations to determine the half-width and line shift for ozone transitions
in the Earth’s atmosphere in support of satellite measurement campaigns such
as NASA’s Earth Observing System (EOS) satellites Aqua and Aura and the European Space Agency’s
MASTER and SOPRANO instruments.
In order to make reliable calculations of the line shape parameters the vibrational of the
polarizability and the dipole moment must be known. However the vibrational dependence of the
polarizability is most important for determining the line shift and this was the focus of Carlos' work. Calculations of pure
rotational transitions were made to determine the coefficients of the atom-atom potential by fits to measurement. The
measurements chosen are for the pure rotation band of O3 so that the vibrational dependence of the
dipole moment and polarizability play no role. Once the intermolecular potential is adjusted the vibrational dependence
of the polarizability can be determined by fits to measurements made for transitions in the 3v3 band,
the v1 band, and the v1 + v2 + v3 band. Once these
adjustments are made calculations will be made for the spectral regions used by the instruments onboard Earth monitoring satellites. The data will also be used in the HITRAN
database.
