    Omar Torres received the B.S. degree in geodetic engineering from Universidad Distrital FranciscoJose de Caldas, Bogota, Colombia, an M.S. degree in meteorology from the University of The Philippines, Quezon City, Philippines, and a Ph.D.degree in atmospheric sciences from Georgia Institute of Technology, Atlanta, GA, USA, in 1990. Between 1989 and 1999, he was associated  with STX and other industry organizations in support of NASA atmospheric remote sensing projects. In 1999 he became a research Associate Professor at the University of Maryland, Baltimore County, Baltimore, MD, USA. He joined Hampton University (Hampton, Virginia)  in 2008  as an Associate Professor at the Department of Atmospheric Sciences.  In 2011, he accepted a position at  NASA Goddard Space Flight Center, Greenbelt, MD, where he continues to carry out research work  in UV atmospheric remote sensing applications with special emphasis in the characterization of aerosol absorption properties from satellite UV observations by the Total Ozone Mapping Spectrometer and Ozone Monitoring Instrument sensors. He has authored and coauthored over 70 peer-reviewed publications.

    Brief Bio

    Omar Torres received the B.S. degree in geodetic engineering from Universidad Distrital FranciscoJose de Caldas, Bogota, Colombia, an M.S. degree in meteorology from the University of The Philippines, Quezon City, Philippines, and a Ph.D.degree in atmospheric sciences from Georgia Institute of Technology, Atlanta, GA, USA, in 1990. Between 1989 and 1999, he was associated  with STX and other industry organizations in support of NASA atmospheric remote sensing projects. In 1999 he became a research Associate Professor at the University of Maryland, Baltimore County, Baltimore, MD, USA. He joined Hampton University (Hampton, Virginia)  in 2008  as an Associate Professor at the Department of Atmospheric Sciences.  In 2011, he accepted a position at  NASA Goddard Space Flight Center, Greenbelt, MD, where he continues to carry out research work  in UV atmospheric remote sensing applications with special emphasis in the characterization of aerosol absorption properties from satellite UV observations by the Total Ozone Mapping Spectrometer and Ozone Monitoring Instrument sensors. He has authored and coauthored over 70 peer-reviewed publications.
