“…It is associated with the initiation of complete 20 freeze over. After that, brightness temperature gradually increases by about 10 K as lake ice thickness grows (Kang et al, 2010(Kang et al, , 2014. It can reach 100-140 cm on Baikal, 40-60 cm on Ladoga.…”

“…It was found in (Kang et al, 2010;Kang, 2012;Kang et al, 2014) that at 18.7 GHz V-pol, brightness temperature greatly depends on ice thickness. The results obtained in these works enabled the authors to develop an algorithm for the determination of 10 phenology phases of lake ice cover from 18.7 GHz H-pol (Kang, 2012;Kang et al, 2012) data, as well as calculate simple regression dependencies of ice thickness on 18.7 GHz V-pol brightness temperature (Kang, 2012;Kang et al, 2014) for GBL and GSL.…”

Abstract. The paper presents a theoretical analysis of seasonal brightness temperature variations at a number of large freshwater lakes -Baikal, Ladoga, Great Bear Lake (GBL), Great Slave Lake (GSL), and Huron -retrieved from Microwave Imaging Radiometer with Aperture Synthesis (MIRAS) data (1.4 GHz) of the Soil Moisture and Ocean Salinity (SMOS) satellite. The analysis was performed using the model of microwave radiation of plane layered heterogeneous nonisothermal medium. The input 15 parameters for the model were real regional climatological characteristics and glaciological parameters of ice cover of the study lakes. Three distinct seasonal brightness temperature time regions corresponding to different phenological phases of the lake surfaces: complete ice cover, ice melt and deterioration, and open water, were revealed. The paper demonstrates the possibility to determine the beginning of ice cover deterioration from satellite microwave radiometry data. The obtained results can 20 be useful for setting the operating terms of winter crossings and roads on ice, since with the beginning of ice deterioration, these transportation routes across water bodies (rivers, lakes, water reservoirs) become insecure and cannot be used any more.

During the International Polar Year (IPY), comprehensive observational research programs were undertaken to increase our understanding of the Canadian polar cryosphere response to a changing climate. Cryospheric components considered were snow, permafrost, sea ice, freshwater ice, glaciers and ice shelves. Enhancement of conventional observing systems and retrieval algorithms for satellite measurements facilitated development of a snapshot of current cryospheric conditions, providing a baseline against which future change can be assessed. Key findings include: 1. surface air temperatures across the Canadian Arctic exhibit a warming trend in all seasons over the past 40 years. A consistent pan-cryospheric response to these warming temperatures is evident through the analysis of multi-decadal datasets; 2. in recent years (including the IPY period) a higher rate of change was observed compared to previous decades including warming permafrost, reduction in snow cover extent and duration, reduction in summer sea ice extent, increased mass loss from glaciers, and thinning and break-up of the remaining Canadian ice shelves. These changes illustrate both a reduction in the spatial extent and mass of the cryosphere and an increase in the temporal persistence of melt related parameters. The observed changes in the cryosphere have important implications for human activity including the close ties of northerners to the land, access to northern regions for natural resource development, and the integrity of northern infrastructure.
