    ALOS PRISM L1C

    This collection provides access to the ALOS-1 PRISM (Panchromatic Remote-sensing Instrument for Stereo Mapping) OB1 L1C data acquired by ESA stations (Kiruna, Maspalomas, Matera, Tromsoe) in the ADEN zone, in addition to worldwide data requested by European scientists. The ADEN zone was the area belonging to the European Data node and covered both the European and African continents, a large part of Greenland and the Middle East. The full mission archive is included in this collection, though with gaps in spatial coverage outside of the ADEN zone. With respect to the L1B collection, only scenes acquired in sensor mode with a Cloud Coverage score lower than 70% and a sea percentage lower than 80% are published: Orbits: from 2768 to 27604 Path (corresponds to JAXA track number): from 1 to 665 Row (corresponds to JAXA scene centre frame number): from 310 to 6790. The L1C processing strongly improve accuracy compared to L1B1 from several tenths of metres in L1B1 (~40 m of northing geolocation error for Forward views and ~10-20 m for easting errors) to some metres in L1C scenes (< 10 m both in north and easting errors). The collection contains only the PSM_OB1_1C EO-SIP product type, using data from PRISM operating in OB1 mode with three views (Nadir, Forward, and Backward) at 35 km wide. Most of the products contain all three views, but the Nadir view is always available and is used for the frame number identification. All views are packaged together; each view, in CEOS format, is stored in a directory named according to the JAXA view ID naming convention.

    Cloud-free collections key for land monitoring

    Satellite imagery is a crucially important tool for monitoring the land, but cloud cover can often block parts of Earth’s surface from view, limiting subsequent analyses.

    ALOS PRISM L1C European Coverage Cloud Free

    This collection is composed of a subset of ALOS-1 PRISM (Panchromatic Remote-sensing Instrument for Stereo Mapping) OB1 L1C products from the ALOS PRISM L1C collection (DOI: 10.57780/AL1-ff3877f) which have been chosen so as to provide a cloud-free coverage over Europe. 70% of the scenes contained within the collection have a cloud cover percentage of 0%, while the remaining 30% of the scenes have a cloud cover percentage of no more than 20%. The collection is composed of PSM_OB1_1C EO-SIP products, with the PRISM sensor operating in OB1 mode with three views (Nadir, Forward and Backward) at 35 km width.
