The Hagler Institute HEEP fellowship is providing me a valuable opportunity to broaden my scientific background knowledge and horizons, and learn state-of-the-art advances in my research field by working with Faculty Fellow Dr. Michael King. I am working on satellite atmospheric remote sensing research in the Department of Atmospheric Sciences. Dr. King suggested that I should use Deep Blue aerosol satellite retrieval data to validate my findings of polluted dust types with non-uniform spatial distributions from CALIPSO lidar observations. Dr. King noticed in my results that there were unusually strong industrial polluted dust concentrations in North Africa. I tried to use co-located Deep Blue data to see the aerosol absorption properties, optical thickness, and land reflectance. I found that my anomaly results are due to stronger dust aerosol loading and larger particle size over North African desert. We summarized the findings and attended the AOGS meeting held in Beijing, August 2016. In the meeting, I was suggested to use PARASOL polarization data to further validate the findings and we presented the results in The 3rd A-train Symposium held in California, April 2017. Inspired by Dr. King’s previous work of bi-spectral reflectance retrieval algorithm, I am now developing a new algorithm to simultaneously retrieve dust aerosol optical thickness and size using LIDAR observation.

Dr. King also gave me many inspiring suggestions on my other research, the similarity in cloud optical properties retrieval. Following his suggestions, I extended the discussion of the similarity to both retrieved cloud optical thickness and particle size. We wrote a paper and published it in a journal this year.

Mr. Ding is expected to graduate in December 2018.
