Regular readers of our blog may recall that one of our Atmospheric Sciences graduate students was awarded a prestigious NASA Earth System Science Fellowship (NESSF) last year. Yingxi Shi continues to impress peers and colleagues with her research, having been awarded the Outstanding Student Paper award for the past AGU (American Geophysical Union) fall meeting. See below for her paper title and abstract:

Evaluation of the MODIS Deep Blue aerosol product over the North Africa Regions for aerosol forecasts related applications

Yingxi Shi1, Jianglong Zhang1, Jeffrey S. Reid2, and Christina N. Hsu3

The MODIS Deep Blue aerosol product provides aerosol properties over bright surface regions such as the Saharan desert with a wide spatial coverage that is of a great value to applications such as aerosol data assimilation and aerosol forecasts. The reported uncertainties for the MODIS Deep Blue aerosol optical depth are on the order of 20-30% of the AERONET data.  A noise and bias reduced, quality assured aerosol product with well-categorized error statistics, however, is needed for advanced applications such as aerosol data assimilation.

In this study, we evaluated the noise and uncertainties of the MODIS Deep Blue aerosol product using both ground based observations and space-borne observations from other sensors, such as MISR.  Uncertainties in the MODIS Deep Blue product were analyzed as functions of surface characteristics, observational conditions, and aerosol microphysics properties.  The possibility of including the MODIS Deep Blue aerosol product in aerosol modeling and aerosol forecasts were also explored.

Congratulations to Yingxi on this recognition. Yingxi’s advisor is Dr Jianglong Zhang who was the 2011 Dean’s Lecture Series Speaker at the recent Graduate School Scholarly Forum.
