This report describes the work done at Ifremer on satellite remote sensing over sea ice using different microwave sensors, in particular work done in WP6 and linked to data delivered through WP2.

We present and assess the data that have been prepared and/or improved (exploited) during the INTAROS project. This refers to data characterization, making the data accessible, creating new datasets, extended the time series from satellites. This also includes data upgraded in the framework of overlapping projects (as for instance CMEMS) but not made available before INTAROS.

This document focus on how existing observations and data products can enhance the existing observation system through data exploitation.
