PO.DAAC is pleased to announce the new dataset, SARAL Near-Real-Time
Value-added Operational Geophysical Data Record Sea Surface Height
Anomaly. This value-added dataset is intended to provide improved
accuracy near-real-time (NRT) sea surface height anomaly (SSHA) measurements
for the SARAL/AltiKa mission. The data are available 7-9 hours after
measurement. It is based on the official OGDR-SSHA, but takes advantage
of several improvements, most notably for the orbit altitude, but also for
the sea-state bias and wind speed. The improved orbit is based
upon near-real-time inter-satellite SSHA crossover differences with
OSTM/Jason-2. This produces a more accurate orbit altitude of 1.5 cm (RMS)
for SARAL, by taking advantage of a near-real-time GPS-based orbit for
OSTM/Jason-2. These data are available with level 2 processing (swath).
