description: 'FOR EXPERT USE ONLY. The Sensor Geophysical Data Records (SGDR) files from the Ocean Surface Topography Mission (OSTM)/Jason-2 contain full accuracy altimeter data, with a high precision orbit (accuracy 1.5 cm), provided approximately 35 days 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. Most importantly the SGDR contains waveforms, which are typically used for retracking the orbit. These data are distributed by NOAA NODC (National Ocean Data Center).'
