Summary

Abstract: ABSTRACT: This collection of data contains OSTM/Jason-2 Auxiliary data files. OSTM/JASON-2 is a follow-on mission continuing the TOPEX/Poseidon and Jason-1, and is designed to ensure continuity of high quality measurements for ocean science and to provide operational products for assimilation and forecasting applications. The Jason-2 satellite was launched on 20 June 2008 and reached its nominal ... repetitive orbit on 4 July 2008. These data are archived at the National Oceanographic Data Center (NODC) as accession 0044983 (http://www.nodc.noaa.gov/cgi-bin/search/prod/accessionsView.pl/deta...) and distributed through the NOAA/NESDIS Comprehensive Large Array-data Stewardship System (CLASS, http://www.class.noaa.gov).

SUPPLEMENTAL INFORMATION: Satellite altimetry data applications include validation and assimilation into global wave models, high seas hazards monitoring, sea surface height and ocean currents (hurricane intensity forecasts and assimilation into operational ocean models, multi-mission altimetry, fisheries, and marine transport.

CURRENTNESS REFERENCE: ground condition

SPATIAL DATA ORGANIZATION INFORMATION
Indirect Spatial Reference: Jason-2's orbit is identical to that of Jason-1 (and that of Topex/Poseidon previously). It is optimized to study large-scale ocean variability and to provide coverage of 90% of the world's oceans over a ten-day cycle. Jason-2's high altitude (1,336 kilometres) reduces interactions with the Earth's atmosphere and gravity field to a minimum, thus making orbit determination easier and more precise. The orbit inclination of 66 degrees North and South enables the satellite to cover most of the globe's unfrozen oceans. The orbit's repeat cycle is just under 10 days (9.9156 days to be precise, i.e., 10 days minus two hours) - in other words, the satellite passes over the same point on the Earth's surface (to within one kilometre) every ten days. This cycle is a trade-off between spatial and temporal resolution designed for the study of large-scale ocean variability. The fact that the orbit is prograde and not sun-synchronous also avoids aliasing of different tidal components at the same frequency. The orbit is also designed to pass over two dedicated ground calibration sites: Cap Senetosa in Corsica and the Harvest oil rig platform in California, USA.
Direct Spatial Reference: Point
SDTS Point and Vector Object Type: Point

NATIVE: Binary, NetCDF, ASCII, and Gridded Information in Binary Form (GRIB)

Electronic download (FTP) of the data is free. There is a fee for copies of data on physical media. Optical disks are $25.00 per unit and magnetic tape is $100 per unit. Price does not include additional service and handling costs.

Purpose: PURPOSE: Auxiliary data files used to generate Level-2 products. Includes both static tabular data files and dynamic files which change/grow over time. Auxiliary files are produced outside of the Ocean Surface Topography Mission (OSTM) but are used in the production of Level-2 products.
