Title : On the estimation of lake ice thickness and on-ice snow depth from satellite observations

Abstract :

The estimation of lake ice thickness by remote sensing means has been the topic of recent investigations by my research group at the University of Waterloo and one that I am further exploring with colleagues at LEGOS. In this talk I will present the progress we have made to date on :

1) the retrieval of ice thickness from microwave (AMSR-E) and thermal (MODIS) sensors

2) our understanding of radiation interactions with snow and ice properties on lakes.

Intensive field measurement campaigns using ground-based scatterometers (Ku- and X-band) as well as radiative transfer and 1-D thermodynamic lake ice modeling experiments have been essentials to the development of our satellite-based retrieval algorithms and the identification of challenges and opportunities for the use of C-, Ku- and Ka-band radar altimetry in the estimation of ice thickness and on-ice snow depth for high-latitude lakes.
