A Microcontroller-Based Architecture to Reduce Gravimeter Output for the Effect of Meteorological Parameters

Continuously running gravimeters are usually adopted to overcome the drawbacks of discrete measurements that are used to monitor gravity changes in volcanic areas (i.e., inaccessibility during wintertime). Exogenous environmental parameters, however, usually affect the performance of these devices, and suitable analytical methodologies are adopted to compensate for these effects. This paper aims to demonstrate the features of the nonlinear compensation strategy that was introduced by the author in the previous works when a real-time reduction of the gravimeter output for the effect of meteorological parameters has to be performed. Moreover, a microcontroller-based electronics that implements such real-time compensation strategy is presented.
