Observation of Flooded Ice in Arctic Regions
The remote detection of flooding in the Arctic ice pack has been difficult to accomplish using conventional techniques. We have examined a case of Arctic flooding (8 June 1989) with NOAA and DMSP visible and infrared measurements supplemented by DMSP microwave imager (SSM/1) data. Analysis of visibl...

The remote detection of flooding in the Arctic ice pack has been difficult to accomplish using conventional techniques.

Analysis of visible and infrared data for a sunglint region was used to show the distribution of flooding at 72 deg N, 135 deg W. A simple model was developed for the radiative transfer at microwave wavelengths through a bring layer over ice. The predictions of the model were found to be consistent with the spatial behaviour of the SSM/I measurements.
