Monitoring lake ice phenology from CYGNSS: Algorithm development and assessment using Qinghai Lake, Tibet Plateau, as a case study
Ghiasi, Yusof; Duguay, Claude R.; Murfitt, Justin; Yuhau, Wu (Mark); Asgarimehr, Milad (University of Waterloo, 2023-05-14)This study introduces the first use of Global Navigation Satellite System Reflectometry (GNSS-R) for monitoring lake ice phenology. This is demonstrated using Qinghai Lake, Tibetan Plateau, as a case study. Signal-to-Noise ... -
Observing Scattering Mechanisms of Bubbled Freshwater Lake Ice Using Polarimetric RADARSAT-2 (C-Band) and UW-Scat (X- and Ku-Bands)
Gunn, Grant Edward; Duguay, Claude R.; Atwood, Donald K.; King, Joshua; Toose, Peter (IEEE, 2018-05-01)A winter time series of ground-based (X- and Ku-bands) scatterometer and spaceborne synthetic aperture radar (SAR) (C-band) fully polarimetric observations coincident with in situ snow and ice measurements are used to ... -
The Role of Lake Physical Variables and Atmospheric Forcings on the Change in Algal Biomass in North American Great Lakes
Dallosch, Michael; Duguay, Claude R.; Kheyrollah Pour, Homa (University of Waterloo, 2023-05-15)The perceived rise in algal biomass/bloom trends globally is assumed to be a result of climate change, however the assessment of interactions with atmospheric forcings are often limited to lab/mesocosm experiments and ...
