blue arrow DESCRIPTION

International Polar Year (IPY), focusing on the north and south polar regions, aimed to investigate the impact of how changes to the ice sheets affect ocean and climate change to the habitats in these regions. IPY was a collaborative project involving over sixty countries for two years from March 2007 to March 2009. To meet the project goal, world space agencies observed these regions intensively using their own Earth observation satellites.

One of these satellites, ALOS - with the PALSAR (Phased Array type L-band Synthetic Aperture Radar) sensor - observed these regions independently from day-night conditions or weather conditions.

Carrying on this initiative, ESA is providing the ALOS PALSAR IPY Antarctica dataset, which consists of full resolution ALOS PALSAR ScanSAR WB1 products (Level L1.5, 100m spatial resolution, 250-350Km swath) over Antarctica from 2008 to 2010 (Cycles 21 - 24, from Jul to Dec 2008; cycles 27 – 31, from May 2009 to Mar 2010). The extension of this dataset by more recent acquisitions over Antarctica is currently on going.
