    CryoSat products

    CryoSat's primary payload is the SAR/Interferometric Radar Altimeter (SIRAL) which has extended capabilities to meet the measurement requirements for ice-sheet elevation and sea-ice freeboard. CryoSat also carries three star trackers for measuring the orientation of the baseline. In addition, a radio receiver called Doppler Orbit and Radio Positioning Integration by Satellite (DORIS) and a small laser retroreflector ensures that CryoSat's position will be accurately tracked. More detailed information on CryoSat instruments is available on the CryoSat mission page. The following CryoSat datasets are available and distributed to users: Level 1B and L2 Ice products: NRT, LRM, SAR and SARIn Consolidated Level 2 (GDR): (LRM+SAR+SARIN) consolidated ice products over an orbit Intermediate Level 2 Ice products: LRM, SAR and SARIn L1b and L2 Ocean Products: NOP, GOP and IOP Cryo-TEMPO Land Ice Cryo-TEMPO Sea Ice Cryo-TEMPO Coastal Ocean Cryo-TEMPO Polar Ocean Cryo-TEMPO Inland Waters Cryo-TEMPO EOLIS Point Products Cryo-TEMPO EOLIS Gridded Products CryoSat Quaternions Product. Detailed information concerning each of the above datasets is available in the CryoSat Products Overview. CryoSat Ice and Ocean products CryoSat Level 1B altimetric products contain time and geo-location information as well as SIRAL measurements in engineering units. Calibration corrections are included and have been applied to the window delay computations. In Offline products, geophysical corrections are computed from Analysis Auxiliary Data Files (ADFs), whereas in FDM products corrections are computed for Forecast ADFs. All corrections are included in the data products and therefore the range can be calculated by taking into account the surface type. The Offline Level 2 LRM, SAR and SARIn ice altimetric products are generated 30 days after data acquisition and are principally dedicated to glaciologists working on sea-ice and land-ice areas. The Level 2 FDM products are near-real time ocean products, generated 2-3 hours after data acquisition, and fulfill the needs of some ocean operational services. Level 2 products contain the time of measurement, the geo-location and the height of the surface. IOP and GOP are outputs of the CryoSat Ocean Processor. These products are dedicated to the study of ocean surfaces, and provided specifically for the needs of the oceanographic community. IOP are generated 2-3 days after data sensing acquisition and use the DORIS Preliminary Orbit. GOP are typically generated 30 days after data sensing acquisition and use the DORIS Precise Orbit. Geophysical corrections are computed from the Analysis ADFs, however following the oceanographic convention the corrections are available but not directly applied to the range (as for FDM). CryoSat Ice and Ocean products can be accessed through ftp://science-pds.cryosat.esa.int/ via an FTP client and HTTPS under the folders named “SIR_” followed by the data product type and the processing level (e.g., SIR_SAR_L2 for Level 2 SAR data). Additionally, data can be downloaded from all the other services listed in the How to Access Data section. Cryo-TEMPO Products The CryoSat ThEMatic PrOducts (Cryo-TEMPO) projects aim to deliver a new paradigm of simplified, harmonized, and agile CryoSat-2 products, that are easily accessible to new communities of non-altimeter experts and end users. The Cryo-TEMPO datasets include dedicated products over five thematic areas, covering Sea Ice, Land Ice, Polar Ocean, Coastal Ocean and Inland Water. The standard Cryo-TEMPO products include fully-traceable uncertainties and use rapidly evolving, state-of-the-art processing dedicated to each thematic area. Throughout the project, the products will be constantly evolved, and validated by a group of Thematic Users, thus ensuring optimal relevance and impact for the intended target communities. More information on the Cryo-TEMPO products can be found in the Product Handbook and on the Project Website. The products can be accessed through ftp://science-pds.cryosat.esa.int/ via an FTP client and HTTPS under the folders named “TEMPO_POCA_(SI/LI/PO/CO/IW)", where the last two letters are the initials of the thematic area (e.g., SI stands for Sea Ice). Cryo-TEMPO EOLIS The CryoTEMPO-EOLIS swath product exploits CryoSat's SARIn mode and the novel Swath processing technique to deliver increased spatial and temporal coverage of time-dependent elevation over land ice, a critical metric for tracking ice mass trends in support to a wide variety of end-users. The dataset consists of systematic reprocessing of the entire CryoSat archive to generate new L2-Swath products, increasing data sampling by 1 to 2 orders of magnitude compared with the operational L2 ESA product. In addition, the EOLIS dataset is joined with the ESA L2 Point-Of-Closest-Approach to generate monthly DEM (Digital Elevation Model) products. This dataset will further the ability of the community to analyse and understand trends across the Greenland Ice Sheet margin, Antarctica and several mountain glaciers and ice caps around the world. More information on the Cryo-TEMPO products can be found on the Project Website and the products can be accessed through ftp://science-pds.cryosat.esa.int/ via an FTP client and HTTPS under the folders named “TEMPO_SWATH_(POINT/GRID)”, where the last word is used to choose between the available “Point” and “Gridded” datasets. Additionally, Cryo-TEMPO EOLIS products can be visualised and downloaded from the CS2EO Platform. CryoSat Quaternions Product This product contains the attitude quaternions for the CryoSat-2 mission. It is obtained starting from the corrected mispointing angles measured by the platform star trackers. More information on the product can be found in the Algorithm Description and Product Format Specification documents. The quaternions product can be accessed from the CryoSat CalVal FTPS server via an FTPS client, and are located in the “AUX_PROQUA” folder. Users wishing to access the quaternions products should request a personal account to be created by emailing the CryoSat Mission Geophysicist, Dr. Alessandro Di Bella (alessandro.di.bella@ext.esa.int).

    SMOS - CryoSat L4 Sea Ice Thickness

    The SMOS-CryoSat merged Sea Ice Thickness Level 4 product, in NetCDF format, is based on estimates from both the MIRAS and the SIRAL instruments with a significant reduction in the relative uncertainty for the thickness of the thin ice. A weekly averaged preliminary product is generated every day by the Alfred Wegener Institut (AWI) by merging the weekly CryoSat Sea Ice Thickness product and the daily SMOS Sea Ice Thickness retrieval. A final product is provided with a latency of about 3-4 weeks using a different global sea ice concentration product and a reprocessed CryoSat product. All grids are projected onto the 25 km EASE2 Grid based on a polar aspect spherical Lambert azimuthal equal-area projection. The grid dimension is 5400 x 5400 km, equal to a 432 x 432 grid centered on the geographic pole. Coverage is limited to the October-April (winter) period for the Northern Hemisphere, due to the melting season, from year 2010 onwards.
