Objective
The main objective of this proposal is
The objective of this study is to develop a pre-operational altimeter data analysis and archival system for ocean currents, and to assess the benefits and cost-effectiveness of the ocean current information provided by such a EO data source for applications by the major customer group: the offshore oil industry on a regional scale to be applied world wide.
Sea level measurements by satellite radar altimeters (RA) represent a relatively low-cost data source for ocean currents estimation. Recent improvements in orbit determinations and geoid modelling, and the availability of overlapping coverage from more than one satellite will be exploited in this project in order to estimate regional currents more accurately which is required by oil companies producing oil from floating platforms primarily in deep offshore areas. These environmental information products and techniques will populate the CEO information exchange EWSE/ES.
The specific objectives are:
1. To produce an accurate high-resolution local altimetric mean sea level for the prime study area.
2. To produce merged ERS-1/2 and Topex/Poseidon data sets for the study area in the period October 1992 to October 1998.
3. To validate altimeter-derived current estimates against in situ measurements.
4. To develop appropriate altimeter data products based on feedback from the customers.
5. To assess the benefits and cost-effectiveness of Near Real Time (NRT) as well as off line altimeter data products during a pre-operational implementation phase.
Working versions of altimeter analysis and presentation tools are already implemented at the partner institutes.
These tools will be modified as necessary and developed to meet the needs of a pre-operational system capable of efflciently processing archieved and new NRT altimeter data on a routine basis and archiving, updating and retrieving the processed altimeter data and ocean current information. The system will be designed to be capable of processing altimeter data on a near-real time basis and flexible enough to accommodate data from multiple (RA) satellites.
Validation against the in situ data collected during the field programme will also enable us to better understand the relationship between the altimeter-derived currents and the vertical structure of the local currents. In addition, error estimates and information on the spatio-temporal scales of variability will be obtained for tuning the altimeter data mapping techniques versus the information needs of the oil exploration industry.
Altimeter data products will be developed in consultation with the customers. Some of the products envisaged at this stage are maps of root mean square sea level variability and eddy kinetic energy, plots of sea level and cross track velocities for selected track segments, time series plots at selected locations, gridded sea level and velocity fields and spatial and temporal statistics. The customer will also assess the benefits and cost-effectiveness of the NRT and off-line altimeter data products in its design and operational responsibilities.
