Based on NRT merged data.
To produce SLA and MSLA in real time and near-real time, the DUACS system uses two flows, based on the same instrumental measurements but with a different quality:
The IGDR that are the latest high-quality altimeter data produced in near-real-time.
The OGDR that includes real time data (OSTM/Jason-2 and Jason-1 OSDR) to complete IGDR. These fast delivery products do not always benefit from precise orbit determination, nor from somexternal model-based corrections (Dynamic Atmospheric Correction (DAC), Global Ionospheric Maps(GIM)). Integration of OGDR data and the introduction of Jason-2/Jason-1 tandem increased the resilience and precision of the system. A better restitution of ocean variability is observed, especially in high energetic areas.
