These data are archived at the National Oceanographic Data Center (NODC) as accession 0044982 (http://www.nodc.noaa.gov/cgi-bin/search/prod/accessionsView.pl/details/44982). The data are distributed through the NOAA/NESDIS Comprehensive Large Array-data Stewardship System (CLASS, http://www.class.noaa.gov). 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. Purpose: Ancillary data files used to generate Level-2 products. Includes both static tabular data files and dynamic files which change/grow over time. Ancillary files are mission specific files used in the production of Level-2 products.

CNES is providing the spacecraft, NASA and CNES are jointly providing the payload instruments and NASA's Launch Services Program at the Kennedy Space Center is responsible for Delta II launch management and countdown operations. After completing the on-orbit commissioning of the spacecraft, CNES will hand over its operation and control to NOAA. NOAA and EUMETSAT will generate the near-real-time products and distribute them to users. NASA's Jet Propulsion Laboratory, Pasadena, Calif., manages the mission for NASA's Science Mission Directorate in Washington. Security Information: Security Classification System: unclassified Security Classification: Unclassified Security Handling Description: not applicable Native Data Set Environment: Static tabular data files and dynamic files which change/grow over time. Ancillary files are mission specific files used in the production of Level-2 products. Data Quality Information: Attribute Accuracy: Attribute Accuracy Report: Please see the Jason-2 User Handbook online at http://www.class.ncdc.noaa.gov/release/data_available/jason/userhandbook.pdf Logical Consistency Report: For each file sent, the Archive performs file validation of the following: file name, file size, and file checksum. CLASS currently performs file name validation. CLASS performs checksum algorithm and routines for additional validation in accordance with the NOAA Environmental Satellite Processing Center (ESPC) to the CLASS Interface Control Document (ICD). Completeness Report: Validation failure will result in placing the file in a hold state. The Access Contact for the Producer will be contacted by CLASS Operations personnel. Positional Accuracy: Horizontal Positional Accuracy: Horizontal Positional Accuracy Report: The orbit maintenance requirements for altimetry missions are usually that the deviation of the actual ground track from the nominal one is kept below 1 km and that the mean local nodal crossing time matches the nominal one to better than to within five minutes. The orbit maintenance strategy aims for minimum disturbance of the payload operation. In-plane manoeuvres are used for altitude adjustment to compensate for the effects of air-drag. This altitude decay controls affects the ground-track repeatability, mainly in the equatorial regions. The frequency of these manoeuvres is determined by the rate of orbital decay, which in turn is determined by the air density, and this is a function of solar activity. The nominal rate for these in-plane manoeuvres is nominally twice a month. They will do not interrupt the operations of most sensors. Out-of-plane corrections are used to correct rectify the steady drift of inclination mainly caused by solar and lunar gravity perturbations. The solar wind also influences inclination, but its contribution is typically an order of magnitude smaller than the one given made by solar and lunar gravity. Inclination drift degrades ground-track maintenance at high latitudes. The drift rate does not depend on air density and corrections are required every few months. As they are out-of-plane they require a 90-degree rotation of the spacecraft, to align the thrusters with the required thrust direction, so these manoeuvres will are performed in during eclipse to avoid the risk of optical sensors viewing the sun. The satellites Topex/Poseidon, Jason-1, and Jason-2 (OSTM) carry three tracking systems (DORIS, GPS, and laser telemetry) that enable their position in space (ephemeris) to be determined with an accuracy of +/- 1 cm.

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 Method: Point Point and Vector Object Information: SDTS Terms Description: SDTS Point and Vector Object Type: Point Spatial Reference Information: Horizontal Coordinate System Definition: Local: Local Description: Jason-2 was placed into the same N-S orbit around the Earth as Jason-1, at an altitude of 1,336 kilometers, inclined 66 degrees, to provide virtually complete coverage of ice-free oceans. Local Georeference Information: Jason 2 orbit parameters: Semi-major axis - 7,714.4278 km Eccentricity - 0.000095 Inclination (sun-synchronous) - 66.039 degrees; Reference altitude (equatorial) - 1336 km Nodal period - 6 745.72 seconds (112'42" or 1h52') Repeat cycle - 9.9151 days Number of passes per cycle - 254 Ground track separation at Equator - 315 km Acute angle at Equator crossings - 39.5 degrees; Longitude at Equator of pass 1 - 99.9242 degrees; Orbital velocity - 7.2 km/s Ground scanning velocity - 5.8 km/s A satellite's orbit parameters tend to change over time as a result of atmospheric drag. In the long term, more or less periodic variations also occur due to instabilities in the Earth's gravity field, solar radiation pressure and other forces of smaller magnitude. Orbit manoeuvres are performed every 40 to 200 days. Intervals between manoeuvres depend chiefly on solar flux and each manoeuvre lasts from 20 to 60 minutes. Wherever possible, they are performed at the end of the orbit cycle, and above solid earth, so that lost data acquisition time is reduced to a minimum.
