Atlas of Antarctic Sea Ice Drift
This project was aimed at
developing a digital Atlas of Antarctic Sea Ice Drift which provides a comprehensive
view of sea-ice motion around Antarctica
- as a reference for contemporary ocean and climate modelling. The
Atlas provides
statistics
on the state of sea-ice cover for numerical weather forecasting models
and ship routing, as well as a
detailed error analysis, such that the data are of practical value in
sea-ice model data
assimilation.
The Atlas is based on data covering almost two decades starting at 1979,
and focusses on sea ice variability over periods ranging from submonthly
to interannual. The data analysis takes advantage of algorithms developed
for ice
drift using data from
passive microwave sensors on polar-orbiting satellites as well as on
drifting buoy data gathered
within various national programs and within the International Programme
for Antarctic
Buoys (IPAB).
The graphical presentations involve various combinations of sea ice variables,
periods and years, being commonly georeferenced in a geographic information
system. They also comprise ice concentrations from SSM/I and weather data
from
NCEP Reanalysis.
A download area provides access to the underlying data in digital form
and can
be
used under the conditions specified in the data agreement, as
follows:
The use of the included data and images is free and should be
acknowledged in the following way if there are no other statements given:
