Short NameOSTM_L2_OST_OGDR_GPS
DescriptionThis dataset is similar to the OSTM/Jason-2 Operation Geophysical Data Record (OGDR) that is distributed at NOAA (ftp://data.nodc.noaa.gov/pub/data.nodc/jason2/ogdr/), but also includes a GPS based orbit and Sea Surface Height Anomalies (SSHA) calculated from that orbit, as supposed to the DORIS based orbit that is already available in the OGDR. It has a 5 hour time lag due to the time needed to recalculate the orbit and SSHA. The GPS orbits have been shown to be more accurate than the DORIS orbits on a near real time scale and therefore produces a more accurate SSHA.

POSEIDON-3
SENSOR
Name: OSTM/Jason-2 RADAR alitmieter (POSEIDON-3)
Swath Width: - km
Description: The Poseidon-3 altimeter, operating at 13.575 GHz (Ku band) and 5.3 GHz (C band), is the primary sensor for the OSTM mission. The measurements made at the two frequencies are combined to obtain measurements of the altimeter range, wind speed, significant wave height, and the ionoshperic correction. The Poseidon-3 package consists of dual redundant altimeter units each of which has low mass and low power consumption.
