Look-Up Tables for SWH RMS test#
This section describes in further details the methodology used to build the SWH RMS Look-Up Tables (LUT) used to filter out bad 1 Hz measurements.
Selected cycles#
The calculation of a SWH RMS LUT is applied to each altimeter mission on 8 cycles. The number of cycles is a trade-off between CPU time and statistical robustness of the proposed diagnostics.
The selected cycles correspond to periods of nominal orbit and nominal functioning of the altimeter:
