I have recently been awarded a Ph.D in atmospheric science from the department of atmospheric and planetary science in Hampton University. I earned my my bachelor’s degree at the Kwame Nkrumah University of Science and Technology in Kumasi, Ghana in 2001 majoring in Mathematics and Statistics. In 2010, I was awarded a Masters degree in Applied Mathematics at Hampton University and then proceeded into a Ph.D program in the Department of Atmospheric and Planetary Science, where was honored to work with Dr. Robert Loughman as my advisor on my Ph.D dissertation.

During my first two years in the Ph.D program, I assisted with several sensitivities studies to prepare the retrieval algorithms for the Ozone Mapping and Profiler Suite (OMPS) Limb Profiler (LP) instrument, which was launched in October 2011,as acknowledged in [1] .
These studies included investigating:
– how each of the three spectral bandpass characteristics used in the retrieval algorithm affected the total ozone retrievals.
– the effect of reducing the number of wavelengths used in the multiple scattering grid (Q-grid) for ozone retrievals for the full orbit.
– the effect of cloud height retrievals on the ozone retrievals.

In my third year, I participated in the radiative transfer model modifications documented in [12], for which I am a co-auther.
My Ph.d dissertation title was “Characterizing Aerosol Properties in the Upper Troposphere and Stratosphere from Limb Scatter Radiance”.
The research involved, finding how well the stratospheric aerosol phase function could be characterized from limb scatter geometry and applied to the retrieval of the stratospheric aerosol extinction profile by using the OMPS forward model and also how this extinction retrieved compared to that of other limb scattering instruments (OSIRIS and SCIAMACHY) that employ different phase functions in their retrieval algorithms.
