CryoSat Ocean Baseline C production online

Further to the news published on 02 November 2017, we inform users that the CryoSat Ocean Product Baseline C production started as planned on 7 October. The first IOP products are already populating the Science Server.

We are currently monitoring the production to iron out some minor noted shortfalls which are delaying the production of a few specific products.

The first GOP data should be produced and disseminated on approximately 6 December. The NOP products (near real time) will not be initially available.

Since new products are now available, users are recommended to download the new version of the CryoSat User Tool (V4.0.0).

Start of CryoSat Ocean Baseline C production on 06 November

As anticipated on 24 October 2017, the new Ocean Baseline C processors will go live on Monday, 06 November. The complete CryoSat Payload Data System is planned to be suspended from 09:00 to 14:00 UTC. During this time there may be a delay in acquiring data, but we do not expect any data to be lost.

Assuming the TTO proceeds successfully, we expect the last GOP Baseline B data to be generated and distributed on the Science Server with a validity of 07 October 2017. All GOP Baseline C data from 07 October to 06 November 2017 will be processed separately and published later.

We would like to remind everybody that the NOP (near real time) products will not be initially available. Therefore the first Ocean Baseline C data we expect to make available on the Science Server will be the IOP products from 06 November, which should be available approximately 24 hours later.

Planned changes for CryoSat Baseline C processors

We would like to announce that we are planning to transfer the new Ocean Baseline C processors into operations.

 

The following changes will occur after the successful deployment of the Baseline C processors:

 

a) The directory structure in the Science Server will be different for the Ocean data and is described in the following table:

File Type

Folder on Science Server

SIR_NOPM1B

SIR_NOP_L1

SIR_NOPR1B

SIR_NOPN1B

SIR_NOPM_2

SIR_NOP_L2

SIR_NOPR_2

SIR_NOPN_2

SIR_IOPM1B

SIR_IOP_L1

SIR_IOPR1B

SIR_IOPN1B

SIR_IOPM_2

SIR_IOP_L2

SIR_IOPR_2

SIR_IOPN_2

SIR_IOP_2_

SIR_IOP_P2P

SIR_GOPM1B

SIR_GOP_L1

SIR_GOPR1B

SIR_GOPN1B

SIR_GOPM_2

SIR_GOP_L2

SIR_GOPR_2

SIR_GOPN_2

SIR_GOP_2_

SIR_GOP_P2P

b) All Baseline B data will be moved into a separate directory. This data will be accessible for six months and after that time it will be deleted.

 

c) The Ocean GOP data missing at the time of the transfer into operations with a validity ranging to 30 October 2017, will be disseminated as Baseline C data with an additional delay of several weeks because they require dedicated reprocessing.

 

d) Scientific data shall now be disseminated in NetCDF format, but the Header data will still be available in the original EE format.

 

More information on detailed planning will be released in the next few days.

New sample CryoSat NetCDF Ocean Products available to users

CryoSat users are informed that a new sample of the latest CryoSat Ocean Products in NetCDF is now available to download below. This test data has been processed with the updated Baseline-C Ocean Processors, which now generate three classes of products, each with different delivery latencies:

  • Near-Real Time Ocean Products (NOP) – delivered 3 hours after acquisition
  • Intermediate Ocean Products (IOP) – delivered 48 hours after acquisition
  • Geophysical Ocean Products (GOP) – delivered 30 days after acquisition


These products are further classified according to the acquisition mode (LRM, SAR and SARIn). For more information on the new NetCDF Ocean Products, please refer to the updated Ocean Product Format Specification document.

Additionally. new global Pole-to-Pole (P2P) products are concatenated multi-mode L2 products generated for IOP and GOP. Two P2P products are generated per orbit, spanning between the North and South poles and combining successive IOP and GOP products respectively. It should be noted that the P2P products have been given the same product name as the Baseline-B L2 IOP and GOP but do not have the same content, frequency or size.

Below is a sample of L1B and L2 GOP data for 21 August 2011 (00:00 – 04:00). Whilst the data sample provided currently includes only L1B and L2 GOP data, users should note that the format of these products is representative of the IOP and NOP data; the processing of these products is the same and the only difference lies in the use of different input auxiliary files.

Please note that these data samples are intended only for the purpose of becoming familiar with the format of the new CryoSat Ocean Products and are not fully representative of the quality that will be provided when this data is opened to the user community.


Users can find other samples of data products here.

Secrets of hidden ice canyons revealed

We are all aware that Antarctica's ice shelves are thinning, but recently scientists have also discovered huge canyons cutting through the underbelly of these shelves, potentially making them even more fragile. Thanks to the CryoSat and Sentinel-1 missions, new light is being shed on this hidden world.

Antarctica is surrounded by ice shelves, which are thick bands of ice that extend from the ice sheet and float on the coastal waters. They play an important role in buttressing the ice sheet on land, effectively slowing the sheet's flow as it creeps seaward.

The ice sheet that covers Antarctica is, by its very nature, dynamic and constantly on the move. Recently, however, there has been a worrying number of reports about its floating shelves thinning and even collapsing, allowing the grounded ice inland to flow faster to the ocean and add to sea-level rise.

While scientists continue to study the changing face of Antarctica, monitor cracks in the surface of the ice that might signal the demise of a shelf and learn how these changes are affecting the biology of coastal waters, they are also aware of dramatic changes taking place below the surface, hidden from view.

CryoSat NetCDF Ocean Products release schedule

Following the publication of some intermediary data samples, CryoSat scientific users are informed that ESA is progressing towards the operational release of the new Ocean Products in NetCDF format.

After the analysis of the test data, it has been decided to apply some minor changes to a few variable attributes (e.g. names). Consequently, it is now envisaged that the initial operational products will be available by October 2017.

It is further noted that the availability of the NOP production may be further delayed for operational reasons.

Product Quality Status Document for CryoSat Ice Products updated

CryoSat users are informed that an updated version of the CryoSat Product Quality Status Document is now available.

This document provides CryoSat users with details of all the known anomalies that are being tracked, that could affect the quality of the CryoSat Ice Level-1 and Level-2 data products operationally generated by the Ice Processor and distributed by ESA.

In addition to this, the details of all the Ice Baseline-D (Q2 2018) evolutions, which have been planned for CryoSat Ice products, as well as some evolutions proposed for future Baseline-E, are also provided.

Upgraded CryoSat NetCDF ocean products releasing soon

CryoSat users are informed that we are at the final stage of the implementation, prior to the release of the new Baseline C CryoSat ocean products for the scientific community.

Our verification teams are currently carrying out extensive checks on the quality and format of the new products generated by the CryoSat Ocean Processor (COP). Once these checks have been successfully completed, the Baseline C Ocean Products will be opened to the whole user community. It is envisaged that initial operational products will be available by September 2017.

In terms of the product content, the main changes involved in the Ocean Baseline C are related to the addition of native SAR/SARIN-mode data over the relevant ocean regions in the geographical mode mask, and a number of new parameters, including updated geophysical corrections.

All evolutions of the COP chain have been considered in parallel of the format change to NetCDF ensuring a better harmonization with other ocean-oriented Altimetry missions. An almost consolidated version of the Product Format Specification document for the new ocean products is now available.

A small test data and additional documentations will be provided to the users soon, in order to test and configure data tools and routines in preparation for the release of the final data scheduled for September.

Giant iceberg in the making

All eyes are on Antarctica's Larsen C ice shelf as a deep crack continues to cut across the ice, leaving a huge chunk clinging on. When it eventually gives way, one of the largest icebergs on record will be set adrift. Even before the inevitable happens, ESA's CryoSat mission can reveal some of the future berg's vital statistics.

Monitored by the Copernicus Sentinel-1 radar pair, the crack in the ice is now around 200 km long, leaving just 5 km between the end of the fissure and the ocean.

While we wait for Sentinel-1 to tell us when this 6600 sq km iceberg is spawned, CryoSat can reveal what the berg's measurements will be.
