Paper Abstract

One of the advantages of combining the higher resolution (approximately equals 25 meters) and re-visit times (three days) of the ERS-1 Synthetic Aperture Radar (SAR) imagery is the capability to image features and processes in the arctic that other systems can not resolve either spatially or temporally. One such process of interest is the dynamics of lead formation and closure and the subsequent growth of ice over the lead region. Much work has been done in the modelling of microwave radar cross section signatures for different stages of ice growth and ice thickness. In this paper we will present the radar cross section evolution of the lead as observed with the ERS-1 SAR. We will demonstrate how the coincident AVHRR imagery on the 24th can be used to estimate where open water signatures are occurring in the SAR image, and then show the subsequent radar cross section changes as the leads close. We will compare the ERS- 1 radar cross section values with in situ measurement.
