Jason-3 GPS based orbit and SSHA OGDR

This is a near real time dataset that provides a GPS based orbit and Sea Surface Height Anomalies (SSHA) from that orbit. It is similar to the Jason-3 Operation Geophysical Data Record (OGDR) that is distributed at NOAA (http://www.nodc.noaa.gov/sog/jason/), but includes the GPS orbit and SSHA as two additional variables. It has a 5 hour time lag due to the time needed to calculate the GPS 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. Forward stream transitioned from processing baseline/version "F" to "G" in January 2025. The change is reflected in the product filename: JA3_GPSOPR_2P<b>f</b>S* -> JA3_GPSOPR_2P<b>g</b>S*
