L2P upstream products monitoring

Data freshness

The following figure presents the monitoring of the aging of the last measurement available at the start time of the DUACS processing. The IGDR/STC (see DUACS processing) products are usually processed with a 24 to 48h delay; OGDR/NRT (see DUACS processing) products are usually processed with few hours delay.

L2P data quality

The following figures present the statistics (mean, standards deviation, number of measurement) at mono-  and multi-mission cross-over locations, before and after calibration processing. Only cross-over with time lag less than 10 days are selected; the diagnostics is computed with a 7 days sampling.

The diagnostic highlights the consistency of the measurements between ascending and descending passes of the reference mission (mono-mission cross-over locations), and between complementary/opportunity and reference mission (multi-mission cross-over locations).

This diagnostic is computed over the Global Ocean.
