Summary
This dataset contains absolute-gravity measurements made using an A-10 absolute gravity meter (Micro-g Lacoste, Inc.) between 2009 and 2017 in the Big Chino Subbasin, Yavapai County, Arizona. Measurements were made about 3 times per year at a total of 33 different stations. Data are presented in tabular form, including relevant parameters used for processing. Data were output by g software (Micro-g Lacoste, Inc.) version 9.12.04.23. A correction for laser-frequency drift was applied, based on regular calibration of the HeNe laser used in the A-10 against an iodine-stabilized laser. A second soil-moisture correction was applied based on satellite soil-moisture measurements, an infiltration model, and the elevation of the terrain surrounding [...]

A correction for laser-frequency drift was applied, based on regular calibration of the HeNe laser used in the A-10 against an iodine-stabilized laser. A second soil-moisture correction was applied based on satellite soil-moisture measurements, an infiltration model, and the elevation of the terrain surrounding each station. This correction is described in detail in the accompanying interpretive report (Kennedy and others, 2019).

Purpose
Gravity data were collected in conjunction with groundwater-level data (published in the USGS National Water Information System) to monitor changes in aquifer storage and identify aquifer storage characteristics.
