CryoSat - Geographical Mode Mask 4.0 released
A new Geographical Mode Mask (v 4.0) is operational from Week 34 2019 (19 August - 26 August) onwards The mask is the basis of the CryoSat mission planning and defines the mode switching of the SIRAL instrument while the satellite revolves around the Earth.
Synthetic Aperture Radar (SAR) (green) is operated over sea-ice areas and over some ocean basins and coastal zones. SAR Interferometric (SARIn) (purple) mode is used over steeply sloping ice-sheet margins, over some geostrophic ocean currents and over small ice caps and areas of mountain glaciers. It is also used over some major hydrological river basins. Low Resolution Mode (LRM) is operated over areas of the continental ice sheets (red), over oceans and over land not covered by other modes.
CryoSat Ocean Baseline C reprocessed 2014 data now available
We're pleased to announce that the reprocessed CryoSat Ocean Baseline C data for all of 2014 has been published on the Science Server and is available for download.
The reprocessing activity is progressing and we are planning to publish batches of six months of data every 20 days. We will follow with another announcement when a full year is available.
CryoSat SIRAL instrument anomaly on 7 July 2019
The CryoSat SIRAL instrument entered stand by mode at 01:53 UTC on 7 July. The instrument was successfully restarted and will resume normal operations by the afternoon of 8 July.
The precise unavailability time will be assessed once normal operations resume.
We are sorry for any inconvenience this may cause.
CryoSat New Geographical Mask in support to the French/US SWOT mission
A new Geographical Mode Mask (v 4.0) will be operational from week 34 (19 to 26 August 2019) onwards. The mask is the basis of the CryoSat mission planning and defines the mode switching of the SIRAL instrument while the satellite revolves around the Earth.
This new map includes several new SAR areas which will be instrumental to support the future SWOT altimetric mission operations and data analysis, particularly in view of computing high resolution regional mean sea surface (MSS).
These areas of SAR acquisitions have been defined by the SWOT EU PI's and will be effective ~2 years prior the SWOT launch, in order to compute robust MSS from which can be removed seasonal effects. With respect to the previous version, the new SWOT areas are reported in yellow in the figure (overlapping the current 3.9 mask version in grey).
To allocate the new SAR areas, the current "SAR Pacific" Box will be removed after the 19 August (see red box in the figure).

Cryosat magnetometer data now available to support Swarm Sciences
We are pleased to announce the new release of magnetic field data recorded by Fluxgate magnetometers operating on-board ESA's CryoSat mission.
The newly released data cover the period August 2010 until December 2018 and will be particularly useful to complement Swarm data in characterizing Earth's magnetic field variations and the near Earth's space environment.
More information on the calibration technique applied to this dataset are available in the CryoSat Magnetometer Data file.
The data, produced as daily CDF files, can be found on the Swarm ftp server in the"#CryoSat-2" folder.
An extended description of this dataset and a scientific paper are under preparation and will be made available soon.
CryoSat abstracts for Ocean Surface Topography Science Team Meeting - deadline 21 June
CryoSat experts and scientific users are encouraged to submit abstracts for the Ocean Surface Topography Science Team Meeting (OSTST, Chicago, 21-25 October 2019).
Abstracts are also required for the splinter session "Science IV: Altimetry for Cryosphere and Hydrology".
Information for the meeting can be found at the OSTST website.
The extended abstract submission closes on Friday, 21 June.
CryoSat NRT data unavailability update
Following the news of 10 June we are glad to inform CryoSat data users that NRT L1b products are available again on the Science Server since 11 June.
L2 data is remains unavailable. We are sorry for any inconvenience caused.
CryoSat Ocean Baseline C reprocessed data from 2013 available
We are glad to inform the CryoSat scientific community that the reprocessed CryoSat Ocean Baseline C data for all of 2013 has been published on the Science Server and is available for download.
The reprocessing activity is progressing and we are planning to publish batches of six months of data every 20 days. We will follow with another announcement when a full year is available.
