COMPARISON BETWEEN BRIGHTNESS TEMPERATURE AND REFLECTIVITY TO THICKNESS OF SEA-ICE
Sea ice is an essential component of the global climate system since it influences and is influenced by changes and variations in the global energy balance and water cycle. In the context of decreasing SIE over the Arctic and an increasing area covered by the seasonal ice, spatial and temporal varia...

Sea ice is an essential component of the global climate system since it influences and is influenced by changes and variations in the global energy balance and water cycle.
