My name is Randy Chase and I am PhD student at the University Of Illinois.

Research Interests

Research Overview

My current research is involved with the Cloud Systems Research Group (UIUC) and the Cloud Physics Group (OU) . I am working with Steve Nesbitt and Greg McFarquhar on cloud/precipitation physics by using, testing, improving and creating remote sensing retrievals of precipitation. I focus mainly on ice-phase precipitation but have a broad interest in microphysics and radar meteorology.

MS Thesis:

Triple-frequency observations of cloud ice and snow. Using the Airborne Precipitation Radar (third generation), three radar frequencies (Ku, Ka and W band) are used in conjunction with in-situ measurements to investigate and evaluate cloud ice/snow retrievals of characteristic size, shape and effective density.

Undergraduate Research

My undergraduate research was involved with the downward transport of ozone rich air within thunderstorms in the Amazon. For two summers I worked under Dr. Jose D. Fuentes at Penn State as part of the Climate Science REU . We used ground based observations of ozone and environmental conditions to detect when ozone enhancements occurred and document their magnitude. See the posters (AMS 2015, AMS 2016) and the manuscript ( Gerken et al. 2016 ) on the left of this page for more information.
