Function: search Citation Identifier: gov.noaa.class:J2-XGDR Description: Abstract: The level 2 geophysical data records derived from instruments aboard the JASON-2 satellite and are available as 3 datatypes: Operational Geophysical Data Records (OGDR), Interim Geophysical Data Records (IGDR) and final Geophysical Data Records (GDR). The OGDRs are near-real-time records and are generated every 3-5 hours. They are based on orbits from DORIS propagator and forecast meteorological fields for the geophysical corrections. The IGDRs are based on preliminary DORIS ephemeris, analyzed meteorological grids, and preliminary auxiliary data files. They have a data latency of 1 - 2 days. The S-IGDR is a superset of the IGDR, containing the original radar echo "waveform" data. The GDRs are based on final high-precision DORIS (perhaps combined with GPS) ephemeris, final meteorological grids, ancillary and auxiliary data files. S-GDR is a superset of the GDR, containing the waveform data. They are generated every 10 days. Sea Surface Height Anomaly (SSHA) files are available for IGDR and GDR. All files are available in NetCDF format and the OGDR is also available in BUFR format. Purpose: To ensure operational continuity for the collection and distribution of high-resolution data on ocean currents and their variations, as well as sea surface height measurements.

The OSTM organisation focuses on the transition towards operational applications. Therefore, the four partners of the OSTM have agreed on a natural cooperation and division of responsibilities. Project management is still in the hands of NASA and CNES, but now with the support of NOAA and EUMETSAT. CNES provides the PROTEUS bus of Jason-2, including the altimeter and the DORIS receiver, while NASA delivers the radiometer, the GPS Receiver, and the Laser Retroreflector Array. NASA procures the launcher and launch services and CNES will be in charge of the overall system integration. EUMETSAT and NOAA provide earth terminals and part of the ground network. In addition, they are responsible for near-real-time product processing, archiving, product dissemination and user support.

Instrument Information: Instrument Full Name: AMR > Advanced Microwave Radiometer Instrument Description: Instrument Type: radiometer Collection Type: microwave Other Collector Description: AMR acquires measurements via three separate frequency channels to determine the path delay of the altimeter's radar caused by atmospheric water vapor. This instrument measures radiation from Earth's surface at three frequencies (18, 21 and 37 GHz). Measurements acquired at each frequency are combined to determine atmospheric water vapor and liquid water content. Once the water content is known, we can determine the correction to be applied for radar signal path delays.

Measurements are made at two frequencies: 2.03625 GHz for precise Doppler measurement and 401.25 MHz for ionospheric correction. The 401.25 MHz measurement is also used for time tagging and auxiliary data.

It uses these signals to acquire phase measurements accurate to about one millimeter and pseudo-range measurements accurate to about 10 centimeters. Instrument Properties Description: The onboard system consists of two independent receivers operating in cold redundancy, each with an omnidirectional antenna, low-noise amplifier, quartz oscillator, sampling converter, and a baseband digital processor communicating via the bus interface. Instrument Reference: Citation Information: Originator: NASA Publication Date: Unknown Title: Reference to NASA document TBD Instrument Information: Instrument Full Name: LRA > Laser Retroreflector Array Instrument Description: Instrument Type: reflector Collection Type: TBD Other Collector Description: The LRA is an array of mirrors that provide a target for laser tracking measurements from the ground. By analyzing the round-trip time of the laser beam, we can locate where the satellite is on its orbit. It is a totally passive reflector designed to reflect laser pulses back to their point of origin on Earth. It is used for the calibration of the Precise Orbit Determination system on the spacecraft. Instrument Properties Description: The retroflectors are placed on the nadir face of the satellite. The totally passive unit consists of nine quartz corner cubes arrayed as a truncated cone, with one cube in the centre and the others arranged azimuthally around the cone. This arrangement will allow laser ranging at field-of-view angles of 360 degrees in azimuth and 60 degrees elevation around the perpendicular. The retroreflectors are optimised for a wavelength of 532 nanometers (green), offering a field of view of about 100 degrees.
