The SARAL Near-Real-Time Value-added Operational Geophysical Data Record Sea Surface Height Anomaly (ALTIKA_SARAL_L2_OST_XOGDR) dataset has been discontinued.
It was provided as a "value-added, best-effort" enhancement to the official SARAL OGDR products generated by CNES and available at AVISO. Furthermore, the OGDR products are typically superseded by longer latency IGDR and GDR products, also available at AVISO.
Please visit AVISO to access the official SARAL data products.
