Many kinds of three axis gravimeters can follow the atmosphere in real time

Utilizing the Impact of Earth and Atmospheric Tides on Groundwater Systems: A Review Reveals the Future Potential

You might want to know that MEMS gravimeters and many kinds of three axis gravimeters can follow earth tides in real time. The three axis broadband seismometers at quiet stations follow the sun moon tidal signal closely. Last year I was talking with someone about drone borne gravity gradiometers.
But your modeling of the earth, ocean and atmospheric response is better. I liked being able to separate the sun moon portions precisely from the earth effects. At high sampling rates where the signal can only arrive from near the earth, or close by, detector arrays can image in 3D if the sun and moon are subtracted off. And those are purely Newtonian. Linear regressions for each axis. It still amazes me that 3 offsets and three multipliers can fit the gravimeter signals with only JPL ephemeris, earth rotation and station location.
If you use gravitational detectors capable of three axis time of flight correlation imaging, you might want to look at sampling rates above 100 MegaSamples per second. Imaging the atmosphere directly has some advantages.
As I was reading, it reminded me of my uncle, R E Collins who wrote Flow of Fluids through Porous Materials. Whenever I see Darcy’s law I think of him.
I think there are several ways to image aquifers directly. I was not sure exactly what you wanted to do. Near the seashores with rising sea surface heights tides and floods will be more important, and those are tide driven (king tides). Economic problem. Subsidence, yes. Microquakes from oil and gas and water. Seawater in clean water. You guys know that well no doubt. I just pick up a lot trying to track all the global sensor networks.
Thanks for you hard work. Infrasound, and high sampling rate barometers. Depends on what you want to do.
