Joshua Richards is a Ph.D. student specializing in Atmospheric Physics at the University of Maryland, Baltimore County (UMBC), building upon his Bachelor of Science in Physics from UMBC. As a NCAS-M II Cohort 1 fellow under the NOAA EPP department, Joshua is currently focusing on the homogenization of the nearly two decades of ozone sonde profiles dataset collected by the Howard University, Beltsville Campus team. His research investigates trends in tropospheric ozone variability across the Baltimore-Washington area. Joshua’s passion for coding and data analysis drives him to compare results from various observation tools including pandora, ozonesonde/radiosonde, lidar, and satellites. His work aims to enhance the quality and reliability of multi-instrumental datasets.
