Missing ionospheric correction, the 25-26th of May. A few ocean tides
measurements are missing over the
Antarctic Ice Shelves. See Table 4.4. This is assumed as nominal.

Geophysical parameters
Due to the missing ionospheric correction and the magnetic solar storm, some
surface elevations are degraded on May 10th-11st.

Orbit cross-over statistics
For cross-overs less than 1 meter shows a mean bias less than -1.4 cm and a
standard deviation less than 38.4 cm. Particularly the standard deviation is
higher than usual.
For cross-overs less than 1 meter shows a mean bias less than -2.0 cm and a
standard deviation less than 35.4 cm. Particularly the mean bias is larger than usual.
