Sea Ice Altimetry
Abstract
Using altimeter data for quantitative information about sea ice is an idea with relatively few proponents. Often the poor spatial sampling given by the altimeter's single-point measurements along widely spaced ground tracks and the difficulty of interpreting altimeter pulse echoes over ice are cited as reasons to avoid altimetry. It is becoming evident, however, that altimetry may be able to make unique measurements. For instance, the altimeter data record reveals the presence of small areas of open water within the pack at concentrations too low to be detected by a passive microwave sensor such as a Special Sensor Microwave/Imager (SSM/1) and too small to be resolved by satellite synthetic aperture radar (SAR)....
