Source: This accession contains the descriptions for the OSTM/Jason-2 orbital
information, which is served through the NOAA/NESDIS Comprehensive Large
Array-data Stewardship System (CLASS): http://www.class.noaa.gov

These files are produced by CNES for offline (IGDR, GDR) data production. For
GPSP1, intermediate level-1 data files are in "RINEX" format and from the
Global Positioning System (GPS) receiver and are used to compute precise GPS
orbits for the spacecraft. For TLE: Two Line Element files are used to
determine the position and velocity of the satellite. Within CLASS, they will
be used directly to determine each orbit's equator crossing longitude and time
which subsequently are used to support spatial search. For MOE and POE,
medium-precision and precision orbital ephemeris files are from the DORIS
system.

Other data/products associated with OSTM/Jason-2 are also provided through
CLASS. They are: Level-2 Geophysical Data Records (GDR), ancillary and
auxiliary data files used to generate Level-2 products, quality reports from
the near real-time altimetry validation system (NRTAVS)and telemetry data. The
descriptions of these data products can also be accessed in other accessions
at NODC.

In this directory, the FGDC metadata for the OSTM/Jason-2 orbital
information is saved in text format. It is created by
NOAA's National Geophysical Data Center (NGDC).

data_URLs.html - A html file provides the URL links directing to the NOAA's
CLASS data system for downloading these datasets.

Update August 31, 2009 - ASCII and XML FGDC metadata files were created by S. Phillips
and Y. Zhang of NODC and placed in the About subdirectory for this accession. These metadata
were created using the NOAA Metadata Manager and Repository (NMMR) system and utilize the
FGDC's Remote Sensing Profile.
