OSTM/JASON-2 OPERATIONAL GEOPHYSICAL DATA RECORD SEA SURFACE HEIGHT ANOMALIES

The Operational Geophysical Data Records (OGDR) files from the Ocean Surface Topography Mission (OSTM)/Jason-2 contain altimeter data, with a precision orbit of 10 cm accuracy, provided approximately 3-5 hours after data collection. The instruments on OSTM make direct observations of the following quantities: altimeter range, significant wave height, ocean radar backscatter cross-section (a measure of wind speed), ionospheric electron content (derived by a simple formula), tropospheric water content, mean sea surface, Sea Surface Height Anomalies (SSHA), and position relative to the GPS satellite constellation. This dataset does contains less parameters than those found in the regular OGDR. The parameters in this dataset relate directly to the calculation of SSHA. These data are distributed by NOAA NODC (National Ocean Data Center).
