摘要:

The remote detection of flooding in the Arctic ice pack has been difficult to accomplish using conventional techniques. We have examined a case of Artie flooding (8 June 1989) with NOAA and DMSP visible and infrared measurements supplemented by DMSP microwave imager (SSM/I) data. Analysis of visible and infrared data for a sunglint region was used to show the distribution of flooding at 72° N, 135° 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. This case study demonstrates the usefulness of using combine visible, infrared, and microwave measurements to differentiate among flooded, broken ice, and open water regions, even in the presence of cloud cover or surface fog
