The Japanese Earth-Observation satellite ALOS, developed by JAXA and launched on 24 January 2006, had the objective to provide the user community with data of sufficient resolution to be able to generate 1:25,000 scale maps.
The mission included optical and an active L-band SAR sensor payload whose high-resolution data may be used for environmental purposes.
On 22 April 2011, the ALOS satellite was lost due to a power anomaly and completed its operations phase.

ESA is pleased to announce the ALOS PALSAR IPY Antarctica dataset is now available to the scientific community through an improved service: it is possible to easily select and download the products from an online map of Antarctica.
Please be aware that in the ALOS FBS_RAW_0P and FBD_RAW_0P collections on the dissemination server the files contained in the .CEOS bundle are incorrectly named as Wide (ScanSAR) products: they are actually products in Fine Beam observation mode as can be seen by the 70 km swath of these acquisitions.
An investigation ascertained that the other collections (polarimetric products and higher level products) are not impacted by the issue.
