Ru-Shan is a research physicist in NOAA's Earth System Research Laboratory in Boulder. Colorado, USA. His principal research interests are 1. The measurement of trace gases and aerosols in the troposphere and lower stratosphere using instruments on board research aircraft, and 2. Interpretive studies addressing stratospheric ozone depletion, the photochemistry of nitrogen oxides, the formation of nitric acid containing aerosols, and the role of black carbon aerosol in climate. Ru-Shan has participated and served as Principal Investigator for a variety of instruments on a number of airborne sampling missions with research aircraft. Ru-Shan is considered by his colleagues to be a Master Craftsman who is outstanding at creating one-of-a-kind scientific devices for laboratory and field instruments.

Education

PhD - Physics, Rice University, Houston, Texas, USA
BA   - Physics, Zhejiang University, China

Current Topics

• Airborne measurements of black carbon aerosol using the NOAA Single Particle Soot Photometer (SP2) and the ozone in the troposphere and lower stratosphere.
• Intercomparison of water vapor measurements in the upper troposphere and lower stratosphere.
• Design and construction of a new ozone instrument for use on the Global Hawk Unmanned Aircraft System (UAS).
• Development of a Chemical Ionization Mass Spectrometer (CIMS) technique for measurement of water at low (<100 ppm) mixing ratios in the tropopause region.
