Altiberg Database of Small Icebergs from Satellite Altimetry, version 3.1

This dataset provides the version 3.1 of the database of small icebergs (lower than 3km in length) detected in Austral and Arctic Ocean, using the high resolution waveforms from spaceborne altimeters from 1992 to 2021. This database is organized by pole (arctic, antarctic) and provides several product levels for each one: * Level 2 products are the individual detections of icebergs along the altimeter tracks. * Level 3 products contains both antarctic polar stereographic 100 km resolution grids of monthly volume of ice and geographic equirectangular (1° in lat x 2° in lon) resolution grids of monthly volume of ice, probability of presence of icebergs and mean iceberg area. Each product organised by altimeter mission (ERS-1, ERS-2, Jason-1, Jason-2, Jason-3, CryoSat-2, Topex, ENVISAT, SARAL, HY2A, HY2B, Sentinel-3A, Sentinel-3B). A merged product combining all the available altimeters is also provided. This database was developed in the frame of Altiberg project, funded by CNES.
