A new study from the sea ice team of the Laboratory of Space Geophysical and Oceanographic Studies (LEGOS) in Toulouse has shown that dual-frequency SARAL and CryoSat-2 altimetric measurements can be used to retrieve consistent snow depth data over sea ice in both hemispheres.
Land-ice is declining globally, raising sea levels worldwide and impacting glacial risks and access to fresh-water in high-mountain glaciers regions. Land-ice monitoring via Earth Observation methods in general, and altimetry in particular, are essential for tracking the current status of ice volume change and its evolution as climate continues to evolve and mitigating actions are being pursued.
Temperatures in the Arctic are rising at an unprecedented rate. This workshop looked at the needs and challenges of working and living in the rapidly changing Arctic and explore how space-based services might help to meet those needs.
Following the introduction of native NetCDF data compression with Ice Baseline E, we have decided to distribute Full Bit Rate (FBR) products as separate .HDR and .nc files instead of a packaged .TGZ file as we have done until now.
For more than 30 years, satellite radar altimetry has been used to continuously monitor the state of the cryosphere and to investigate the impact of global warming on sea level rise. Owing to this, maps of ice sheet elevation and elevation change were derived.
CryoSat L2 geophysical ocean products (GOP) covering the period 11-23 June 2021 were found to have lower quality than nominal products, especially in coastal regions, due to inaccuracies in some of the auxiliary files used in the processing.
