25 passes are missing, and several duplicated files. See Section 3.1

Availability of geophysical corrections

Ocean tide measurements are missing over the Greenland and Antarctic Ice Shelves. See Table 3.5 and Table 3.6.

Geophysical parameters

Nominal

The waveform quality flag is failing (>0) over large parts of orbit 101 over Greenland (pass 201) and Antarctica (pass 202). The OCOG elevation retrievals are degarded, and the UCL ice retracker elevation_ice_sheet_20_ku is set to NaN for most of the passes.

Specific investigations

N/A

Orbit cross-over statistics

For cross-overs less than 1 meter shows a mean bias less than -1.2 cm and a standard deviation less than 37.0 cm. This is nominal

For cross-overs less than 1 meter shows a mean bias less than -1.1 cm and a standard deviation less than 36.3 cm. This is nominal. The orbit 101 show degraded cross-overs over both Greenland and Antarctica.
