Summary
Abstract: ABSTRACT: 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. This collection of data contains OSTM/Jason-2 Near Real-Time Altimetry Validation System Quality Reports (NRTAVS). These data are archived at the National Oceanographic Data Center (NODC) as accession 0044984 (http://www.nodc.noaa.gov/cgi-bin/search/prod/accessionsView.pl/details/44984). The data are distributed through the NOAA/NESDIS Comprehensive Large Array-data Stewardship System (CLASS, http://www.class.noaa.gov). Reports are daily and cover the previous 10-day period.

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. More information: Near Real Time Altimeter Validation System User Handbook, JPL D-35859.

CURRENTNESS REFERENCE: ground condition

SPATIAL DATA ORGANIZATION INFORMATION
Indirect Spatial Reference: 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.
Direct Spatial Reference: Point
SDTS Point and Vector Object Type: Point

NATIVE: Acrobat Portable Document Format (Adobe Systems Incorporated)

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: To monitor high-level science quality of Jason-2 OSTM (Ocean Surface Topography Mission) Operational Geophysical Data Records (OGDR) products. High-precision ocean altimetry measures the distance between a satellite and the ocean surface to within a few centimeters. Accurate observations of variations in sea surface height (ocean topography) provide scientists with information about the speed and direction of ocean currents and heat stored in the ocean. This information, in turn, reveals global climate variations.

ATTRIBUTE ACCURACY REPORT: not applicable

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: The planned archive schedule is expected to begin shortly after launch, and continue through the life of the mission. Information about updates and edits to Jason-2 data is available through CLASS at http://www.class.ncdc.noaa.gov/notification/news.htm#5

LINEAGE/PROCESS STEP:
PROCESS DESCRIPTION: Quality Reports from the Near Real-Time Altimetry Validation System (NRTAVS). Reports are daily and cover the previous 10-day period. The planned archive schedule is expected to begin shortly after launch, and continue through the life of the mission. All QA reports will be archived a minimum of 20 years. All files, including those during the pre-operational phase, will be archived in perpetuity unless the producer makes a specific request to remove the files from online access.
