Snow plays an essential role in governing the surface energy and water budgets at high elevations. Thus, understanding the physical processes of snowpacks formation and melting, as well as analyzing the seasonal evolution of snowpack's microwave emission, over these remote and inhospitable areas are critical.

Through field campaign data, remote sensing observations, and coupling snow hydrology models to radiative transfer models, my research aims to elucidate the propagation of spatial uncertainty in atmospheric forcing from snowpack physics to radiometric and scattering behavior of high-elevation snowpacks. Ultimately, the goal is to separate uncertainty in snowpack microwave measurements (backscattering coefficient and brightness temperatures) from retrieval ambiguity tied to snowpack condition’s spatial variability.
