CryoSat Ocean Baseline C reprocessed data from 2011 available

We are glad to inform the CryoSat scientific community that the reprocessed CryoSat Ocean Baseline C data for all of 2011 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.

New CryoSat Roll Campaign

A CryoSat roll campaign is scheduled on 25 April 2019, from 03:29:00 to 06:50:10 UTC and from 16:01:00 to 19:06:10 UTC. SIRAL instrument routine planning will be suspended and data gaps are possible. NRT users will be most affected.

This campaign is part of the periodic calibration activities to calibrate the interferometric baseline of CryoSat's altimeter and improve the quality of the mission products.

We will notify you when the data will be available and nominal operations are restored.

7th CryoSat Quality Working group Meeting - Final Report

The 7th CryoSat Quality Working Group (QWG) meeting was held at ESA/ESRIN from 26 - 28 November 2018. The QWG#7 was structured around 7 main sessions and involved 43 participants from different operational and research institutes including both CryoSat Expert Support Laboratory, QC and Cal/Val teams, altimetry experts and multi-thematic scientists.
 
The QWG#7 topics addressed both the data quality aspect of operational ice and ocean L1/L2 products, the results from Cal/Val Campaigns as well as the evolutions of core PDGS products and strategic implementation of future Cryo-TEMPO. The latest results about the CryoSat Ocean Processor Baseline-C and Ice Baseline-D Test Data Sets over the ice sheet and ice caps, Sea-Ice and Inland areas were also discussed.
 
These points and much more are addressed in the QWG#7 presentations and the Summary and Recommendation Report which is now available to download.

CryoSat Ocean Baseline C reprocessed data available

We are glad to inform the CryoSat scientific community that the first 6 months of the reprocessed CryoSat Ocean Baseline C data (July-December 2010) have been published on the Science Server and are available for download. 
 
The reprocessing activity is currently progressing and we are planning to publish batches of 6 months of data every 20 days. A web news shall be published when a full year is available.

US government shutdown effects on CryoSat geophysical corrections and parameters

The CryoSat users are informed that the US government shutdown currently on-going is affecting the services that are responsible for providing NOAA's input data products used in CryoSat ice and ocean processing chains.
 
The CryoSat L1b and L2 products with dates of validity starting on 21 December 2018 are therefore affected by this situation. As a consequence, the quality of CryoSat related geophysical corrections and derived parameters (e.g. sea ice concentration in ice products and GPD+ wet tropospheric correction in GOP) are potentially degraded.
 
Users will be informed at a later stage to what extent L1b/L2 parameters are directly or indirectly impacted and once the US services return to normal.

7th CryoSat Quality Working Group Meeting

The 7th CryoSat Quality Working Group (QWG) meeting will take place from 26 to 28 November 2018 and will be hosted by the European Space Agency (ESA) at ESRIN in Frascati (Rome), Italy.

CryoSat QWG and validation experts will attend the meeting to present and discuss their latest results about the CryoSat Ocean Processor Baseline-C (e.g. FDM vs NOP) and Baseline-D Test Data Sets over the ice sheet and ice caps, Sea-Ice and Inland areas.

Download the agenda for the meeting to learn about the presentations.

CryoSat data unavailability update

Further to the unavailability notice published earlier today, we would like to inform users that the maintenance was completed successfully, and the SIRAL instrument resumed operations at 11:10 UTC as originally planned.
 
Full data unavailability shall be consolidated and announced on the CryoSat Data Unavailability Periods page.

CryoSat data unavailability on 04 October 2018

CryoSat scientific data users are informed that due to planned platform maintenance activities, SIRAL will be unavailable today the 04 October 2018 from 09:25:00 UTC (to StandBy).
 
The nominal operations will not be resumed before 11:10:12 UTC (to_SIN), the exact time will be confirmed in a following news item.

CryoSat ICE Baseline-D data sample available

Baseline-D ice data will be released in spring next year and will include several evolutions as well as a new data format (NetCDF).
 
CryoSat scientific users are informed that a sample dataset has been made available hereafter. It is intended to provide this small data set to allow users to update their tools and reading routines prior to the final official products release. This Baseline-D test data set, covering the day 22/10/2013, is available for:
 
Level 1 (SIR_LRM_1b, SIR_SAR_1b and SIR_SIN_1b) and
Level 2 (SIR_LRM_2_, SIR_SAR_2_ and SIR_SIN_2_).
 
In addition, the draft version of the updated L1b and L2 product format specification documents are also available for download.
