Relevant if you're trying to do extremely fine gravity measurements, but for navigation (and with the performance of these sensors), it's not going register much, the natural contours of earth's gravity over longer distances are large compared to these effects.

What about weather conditions? Clouds, heavy rain, hurricanes, etc.
