The modelling of sea ice-melt water ponds for the High Arctic using an airborne line scan camera, and applied to the satellite special sensor microwave/imager (SSM/I)
Melt-water ponds on sea ice in the Northeast Water Polynya (77-82°N, 1-18°W) were mapped using a Line Scan Camera (LSC) mounted on a helicopter. Passive microwave satellite data from the Special Sensor Microwave/Imager (SSM/I) were employed to analyse the temporal trend of radiances of shorefast ice...
