Microwave Observations of Daily Antarctic Sea-Ice Edge Expansion and Contraction Rates
Abstract—Algorithms for estimating sea-ice extent from remotely sensed microwave sensor data can benefit from knowledge of the “a priori ” distribution of the daily expansion and contraction of the sea-ice pack. To estimate the probability distribution of daily Antarctic sea-ice extent change, two i...

| Summary: | Abstract—Algorithms for estimating sea-ice extent from remotely sensed microwave sensor data can benefit from knowledge of the “a priori ” distribution of the daily expansion and contraction of the sea-ice pack. To estimate the probability distribution of daily Antarctic sea-ice extent change, two independent sea-ice datasets are analyzed: sea-ice extent derived from the QuikSCAT scatterometer and ice concentration estimates from the Special Sensor Microwave/Imager. The daily sea-ice advance and retreat is tracked over a four-year period. The distribution of the daily sea-ice advance/retreat from each sensor is similar and is approximately double-exponential. Daily ice-pack statistics are presented. Index Terms—SeaWinds, QuikSCAT, Special Sensor Microwave/Imager (SSMI), sea ice. I. |
