      June 10, 2016 : APS Scientists Observe Mercury Transit with the Public

      On May 9th, 2016, a special celestial event occurred when the planet Mercury lined up exactly with the Sun in the sky as viewed from the Earth. In Hampton, Mercury began to cross the disk of the Sun shortly after sunrise at 7:20am and spent a leisurely seven hours making a sharp, round shadow on […]


      October 23, 2015 : APS Professor Moore Hosts Astronomy Night Event

      The White House announced earlier this year that October 19th of this year was going to be the National Astronomy Night, and invited professional scientists and amateur astronomers to host events around the country.  The goal is to expand access to STEM experiences for the next generation of scientists, engineers, and inventors.  The White House […]

    I am currently a fifth year Ph.D. student. I earned my Bachelor’s degree in Physics from the University of Maryland, Baltimore County in 2014, with a minor in Mathematics.

    Before starting as a graduate student, I spent a summer researching at Hampton University as a part of the CREST Undergraduate Research Experience (CURE), and was later a part of the Lidar Research Group at UMBC.  During CURE, I examined extinction coefficients using data from Hampton University’s Rotational Raman Lidar. As a part of the Lidar Research Group at UMBC, I worked on optimizing code used to determine planetary boundary layer heights and examined the possibility of extending the code to account for a variable Lidar ratio.

    My research interests revolve around Lidar and Ozone, and I currently work under Dr. Patrick McCormick, funded through NOAA CREST.  We worked to develop a scanning Lidar, which will take measurements at various angles between vertical and horizontal.  I have spent most of my research focus on using ground based Lidar to examine Raman scattering and extinction.  My focus now, however, has switched to calibration and validation of the Ozone Mapping and Profiler Suite (OMPS) Limb Profiler instrument on the Suomi-NPP satellite, and incorporating OMPS stratospheric ozone data as an a-priori for the NOAA Unique Combined Atmosphere Processing System (NUCAPS). I plan on comparing the profiles produced by NUCAPS and the OMPS a-priori to other ozone retrievals, through both satellite and ground-based instruments, ranging from the Microwave Limb Sounder (MLS) on Aura to Ozone DIAL LIDAR.

    I spent the summer of 2016 partaking in a NOAA Student Scholarship Internship Opportunity (SSIO) at the NOAA Center for Weather and Climate Prediction in College Park, MD. I worked with the OMPS Science Team, under Dr Larry Flynn. I will continue to work with the OMPS Science Team during my dissertation research.

    I have presented my work on Raman Lidar at the 2014 NOAA NESDIS CoRP Symposium, the 7th Biennial NOAA EPP forum, and the 5th Joint Annual NOAA-CREST/NESDIS-STAR Technical and 14th Advisory Board Meetings.  A poster was presented at both the Symposium and Meeting, while an oral presentation was given at the EPP Forum.  More information about my work in Raman Lidar can be seen in the Raman Lidar projects page, which also contains the research paper I wrote as a part of my participation in CURE.

    My work on OMPS/MLS comparisons has been presented at the 2016 JPSS Science Team Meeting, and the 8th Biennial NOAA EPP MSI Science and Education Forum, where my poster placed first in the Graduate Student section of the Weather Ready Nation Category. A poster will also be presented at the 2017 AMS conference

    Project: Lidar Examination of Raman Extinction and Scattering

    View Project Page

    Raman Extinctinction and Scattering Using Lidar Returns Raman extinction provides a way to determine constituents of the atmosphere remotely using Lidar.  This can be done using retrieved Lidar and radiosonde data in conjunction with the Raman scattering equation.  Different molecules cause different wavelength shifts in the incident beam, which enables concentrations, densities, etc, to be […]

    Project: Ozone Mapping and Profiler Suite Limb Profiler Calibration and Validation

    View Project Page

    The Ozone Mapping and Profiler Suite (OMPS) is a suite of instruments on the Suomi National Polar-orbiting Partnership (S-NPP) satellite that primarily measures Ozone in the atmosphere. It has 3 instruments associated with it, the Nadir Mapper, Nadir Profiler, and Limb Profiler. The Limb Profiler (LP) measures limb scattered radiances over both visible and ultraviolet […]
