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 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.

Improved CryoSat data access

With the aim to improve Earth Observation data distribution services - as recently announced - data from the CryoSat instruments can now be freely downloaded using a dedicated HTTP platform.

The data can also be downloaded through alternative means, which are described on the CryoSat data products page.

CryoSat data anomaly resolved

We would like to inform the CryoSat data users that the anomaly affecting the generation of data on 08 July 2018, has been resolved now.

Previously delayed data have also been generated and all operations are back to normal.
