Repeat microgravity data from Rio Rancho, New Mexico, 2019-2023

This dataset represents the network-adjusted results of relative- and absolute-gravity surveys performed from 2019 to 2023 in Rio Rancho and Bernalillo County, New Mexico. Relative surveys were conducted using a Zero Length Spring, Inc. Burris relative-gravity meter. Absolute-gravity surveys were conducted using a Micro-g LaCoste, Inc. A-10 absolute-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data prior to network adjustment. Non-linear instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations. Vertical gradients between the relative- and absolute-gravity meters were measured at each station where both types of measurement were collected to correlate the measurements of the two instruments. Vertical gradients were measured using a relative-gravity meter and tripod set to the height of the absolute-gravity meter. Relative-gravity differences and absolute-gravity data were combined using least-squares network adjustment, as implemented in the software GSadjust (https://github.com/jkennedy-usgs/sgp-gsadjust). Data are provided for 20 stations collected over 11 discrete surveys.
