Shi Song, PhD Candidate
Shi Song is a Ph.D. Candidate in the Department of Atmospheric and Oceanic Sciences. She is in her fourth year at CU Boulder. Her research interests include understanding the relationship between 3-dimensional (3-D) cloud spectral structures and spectral signatures of radiative quantities of a cloud field such as irradiance, heating rate and cloud radiative effect. Currently she is using a 3-D radiative transfer model – Monte Carlo Atmospheric Radiative Transfer Simulator (MCARaTS) – and spectral measurements of cloud radiation from several field campaigns (e.g., TC4, DC3, SEAC4RS, etc.) to investigate this phenomenon. The investigation covers different spectral regions, whose radiative properties are dominated by different effects (e.g., molecular scattering, aerosol scattering and absorption, gas absorption, and cloud absorption). One of the goals of Shi’s research is understanding how each aspect of the 3-D cloud spatial structure gives rise to the spectral radiative signatures in these different spectral regions and introducing a new spectral parameterization for cloud heterogeneity effect that is applicable for both remote sensing and energy budget studies. Shi also helps with the pre and post-field campaign calibrations of the Solar Spectral Flux Radiometer (SSFR), the group’s main instrument.

Andrew Kren, PhD Candidate
Andrew Kren is a PhD candidate in the Department of Atmospheric and Oceanic Sciences. He is in his fourth year at CU Boulder. His current interests include understanding Sun-Climate connections, and specifically how changes in the Sun may alter the stratosphere and troposphere through various dynamical processes. His first research topic as part of his Comps II work investigated whether the Quasi-Biennial Oscillation (QBO) in the equatorial stratosphere is modulated by solar activity, and whether the well known Solar-QBO interaction could be reproduced in a fully coupled climate model with an internally generated QBO. More recently, Andrew is collaborating with Dan Marsh and Anne Smith, two research scientists at the National Center for Atmospheric Research (NCAR) in Boulder, to examine the interaction of the 11-yr solar cycle with decadal to multi-decadal variability in the ocean and their effect on the stratosphere. To examine this, he is running several climate simulations from the Whole Atmosphere Community Climate Model (WACCM4).
