Estimating lake ice thickness in Central Ontario.

open access: yesPLoS ONE, 2018
Lakes are a key geographical feature in Canada and have an impact on the regional climate. In the winter, they are important for recreational activities such as snowmobiling and ice fishing and act as part of an important supply route for northern ...

Deep Learning‐Based MultiSource Satellite Data Fusion and Downscaling for Tropical Cyclone Wind Fields

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract High‐resolution observations of ocean surface wind (OSW) are crucial for analyzing and forecasting tropical cyclones; however, current data are insufficient. While data sets such as the Cross‐Calibrated Multiplatform (CCMP) and ERA5 provide gap‐free wind fields, their 25 km resolution and tendency to underestimate cyclone wind speeds limit ...

The effect of polarization ratio on RADARSAT wind vector retrievals [PDF]

open access: yes, 2007
In this presentation, the polarization ratios were calculated from AIRSAR polarimetric SAR data and ENVISAT ASAR dual-polarization data; and their empirical alpha parameters which depend on incidence angle were obtained.

Surface deformation (Line of sight) observed by Radarsat-2 InSAR over Southern Ontario, Canada

open access: yes, 2019
The study is to exam if surface deformation occurs in southern Ontario and and if so, if it is related to changes in water storage change. The surface deformation data, derived from a set of 48 Radarsat-2 InSAR images over five years (from Jan.
