ResearchDr. Ying’s research on urban/regional air quality is focused on the following areas: (1) Urban/Regional air quality modeling – Advanced air quality models are used to study the emission, transportation, chemical transformation of airborne pollutants. Current research is focused on the study formation of secondary nitrate and organics under different emission, geographical and meteorological conditions to improve model predictions. Process analysis tools are incorporated into the air quality models to gain insights on the contribution of each simulated process to the overall pollutant concentrations. (2) Source apportionment of airborne particulate matter – Advanced source oriented air quality models are used to determine the source contributions to particulate matter and attribute the effect of different sources on visibility, climate change and human health. Correctly and efficiently determining the source contribution to particulate matter is important for policy makers to design efficient emission control strategies. (3) Parallel computing - Clustered workstations running GNU/Linux (beowulf system) is used as a powerful and flexible computing environment for the air quality model simulations. More efficient parallel algorithms are developed to accelerate the air quality model calculation.
This is the 35-node beowulf system current in operation. Each node contains a quad-core Intel Q6600, 2G of RAM and a 250G local hard drive. The nodes are connected through two stacked NETGEAR GS724TS gigabyte Ethernet switchers. The system is currently running x86_64 CentOS4.6. The blinking green, blue and red LEDs give an alien feeling and are most enjoyable when all the other light sources are turned off. Refereed Journal PublicationsIn Preparation In Review 14.
