CryoSat Mission. 7 years in Operations: Status and Achievements

Tommaso Parrinello, CryoSat Mission Teams

ESA, Italy

CryoSat mission will reach its 7th years of operational life in April 2017. Since its launch, it has delivered high quality products to the worldwide cryospheric and marine community that is increasing every year. Scope of this paper is to describe the current mission status and programmatic highlights on the next scientific development of the mission in its extended period of operations.

CryoSat Product Evaluation & Evolution after 7-years in Operation

Jérome Bouffard1, Tommaso Parrinello2, Pierre Féménias2

1RHEA c/o ESA, Italy; 2ESA

CryoSat, the 1st Polar European Mission, is equipped with a Ku band radar altimeter, operating in 3 modes (LRM, SAR, SARin). The main mission objectives are to measure the regional and basin-scale changes in the thickness of sea-ice and, in the elevation of the ice sheets and mountain glaciers. Beside its ice-monitoring objective, CryoSat also provides valuable observations for ocean scientific and operational applications. To achieve these goals, the CryoSat data are processed by ESA both over the Ice and the Ocean surfaces with two independent processors. The ice products are generated with the Baseline C ice processors, including processor upgrades such as an improved retracker optimized for the freeboard retrieval. The CryoSat Ocean data are currently generated with the Baseline B CryoSat Ocean Processors (COP), operating since April 2015. The CryoSat ice and ocean products have to meet the highest performance. In this respect, the ESA operational data need to be routinely Quality- Controlled and thoroughly Validated (QCV). Based on the QCV outcomes from ESA multi-national partners and the feedback from the Scientific user Community, the data products continuously evolve in order to accommodate a wide range of users focused on the Sea ice, Land Ice and Ocean domains. The main objectives of this paper are to give an overview of main QCV results and product improvements made possible over the past 7-years; as well as to present the processing algorithm upgrades being implemented for future ice and ocean Processing Baselines.

The Sentinel-3 Altimetry Land Mission: Overview and Status of Operations

Pierre Féménias, Susanne Mecklenburg

ESA ESRIN, Italy

The Copernicus Programme, being Europe’s Earth Observation and Monitoring Programme led by the European Union, aims to provide, on a sustainable basis, reliable and timely services related to environmental and security issues. The Sentinel-3 mission forms part of the Copernicus Space Component. Its main objectives, building on the heritage and experience of the European Space Agency’s (ESA) ERS and ENVISAT missions, are to measure sea-surface topography, sea- and land-surface temperature and ocean- and land-surface colour in support of ocean forecasting systems, and for environmental and climate monitoring. The series of Sentinel-3 satellites will ensure global, frequent and near-real time ocean, ice and land monitoring, with the provision of observation data in a routine, long-term (up to 20 years of operations) and continuous fashion, with a consistent quality and a high level of reliability and availability.

The Sentinel-3 mission is jointly operated by ESA and EUMETSAT. ESA is responsible for the operations, maintenance and evolution of the Sentinel-3 ground segment on land related products and EUMETSAT for the marine products. All facilities supporting the Sentinel-3 operations are in place and operational:

  • Data acquisition and near real time (NRT) product generation, including data downlink and processing (NRT and offline) will be performed at Svalbard station,
  • Processing and Archiving Centres (PAC), which will perform the Sentinels’ systematic non-time-critical data processing, the on-the-fly data processing for specific cases and the reprocessing in case of processing algorithms or calibration parameters upgrades:
    • OLCI processing and archiving will be performed at DLR,
    • SRAL processing and archiving will be performed at CLS,
    • SLSTR and Sentinel-3 synergy products processing and archiving will be performed by ACRI,
    • EUMETSAT’s marine centre acts as PAC for marine products.
    • Missions Performance Centre (MPC): Operational Quality Control, Expert Support Laboratories (ESL), Calibration and Validation
    • Sentinels POD Service, which generate the orbit products for the Sentinels-1, -2 and -3 missions and perform the performance monitoring of the GNSS sensors.

The Sentinel-3 ground segment systematically acquires, processes and distributes a set of pre-defined core data products to the users. For a detailed description of the core data products please see https://earth.esa.int/web/sentinel/missions/sentinel-3/data-products.

This paper will provide an update on the status of the ground segment operations for the Sentinel-3 mission since launch, including an outlook on the performances of the Altimetry Land products and ground processing.
