AAS_4301_Scatterometer-derived_ice_thickness_proxy
All scientific data collected by the Australian Antarctic program (AAp) are eventually described in the Catalogue of Australian Antarctic and Subantarctic Metadata (CAASM). CAASM can be used to search through AAp data descriptions, and it also provides links to access publicly available datasets, which can either be immediately downloaded or obtained from the Australian Antarctic Data Centre (AADC).

Description
This dataset is a time series of sea ice freeboard proxy estimation based on ASCAT C-band backscatter measurements.
File format is unformatted binary, with each file 632*664 pixels, and 32 bits per pixel (floating point).
Two datasets are presented here, as detailed in University of Tasmania Honours thesis by Nicola Ramm: "unmasked", i.e., no attempt to mask multiyear and marginal sea ice, and "masked", where these are masked based on backscatter.
The grid used by this dataset is described here:
https://nsidc.org/data/polar-stereo/ps_grids.html
The methods are described in an honours thesis by Nicola Ramm, University of Tasmania.
Purpose
A proxy measurement of sea ice freeboard, as detailed in University of Tasmania Honours thesis by Nicola Ramm.
Quality
ASCAT data calibration prior to July 2007 is of suspected poorer quality.
