Treatment of the solid earth component of the pole tide

[leuliett]

Kleinherenbrink et al. 2018 note that the solid Earth tide in RADS does not include the solid Earth component of the pole tide and that the pole tide field is a combination of solid+ocean tide. In order to compare altimetry with tide gauges. In order for users to consistently compare RADS data to land-based sea level from gauges, etc. either:

1. The solid earth and pole tide fields could be reconfigured or
2. A new field for the ocean component only of the pole tide could be added to RADS.

The second option may be preferable because it is the least disruptive.
