This dataset contains absolute-gravity measurements made using an A-10 absolute gravity meter (Micro-g Lacoste, Inc.) in 2019 in Pinal County, Arizona. Measurements were made at a total of 19 different stations used by the Arizona Department of Water Resources (ADWR) to monitor aquifer-storage changes. Data are presented in tabular and spatial vector (point) 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.

This dataset includes gravity observations collected on the Coconino Plateau, Arizona, from 2015 to 2019 and reductions that were used to arrive at the gravity residual reported in the associated publication (Wildermuth, XXXX). Relative-gravity surveys were carried out using ZLS Burris relative-gravity meter. Absolute gravity values were taken from the closest NGS stations and relative-gravity differences were combined with nearby absolute gravity values using a least-squared network adjustment, as implemented in the software Gravnet (Hwang, C., Wang, C., Lee, L., 2002. Adjustment of relative gravity measurements using weighted and datum-free constraints. Comput. Geosci. 28, 1005–1015). Additional information about...

Groundwater budgets were compiled from 2002 to 2012 and 2020 for the Sierra Vista Subwatershed for the Upper San Pedro Partnership. In 2012, the annual groundwater budget was estimated to be about -5,000 acre-ft per year (negative values indicate a deficit, where more water is removed from the system than is being returned; positive values indicate a surplus, where more water is entering the system than is being removed). In 2020 the Sierra Vista Subwatershed groundwater budget deficit has decreased to about -3,600 acre-ft per year. This is the smallest deficit calculated since the Upper San Pedro Partnership started to track the groundwater budget beginning in 2002. The total water budget uncertainty is estimated...

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...

Relative-gravity surveys were carried out using a ZLS Burris relative-gravity meter. The effect of solid Earth tides and ocean loading were removed from the data. Instrument drift was removed by evaluating gravity change during repeated measurements at one or more base stations. Absolute-gravity surveys were carried out using a Micro-g LaCoste, Inc. A-10 absolute-gravity meter. Vertical gradients between the different measuring heights of the absolute- and relative-gravity meters were measured using a relative-gravity meter and fully-adjustable tripod, and used to correlate the measurements between the two instruments. Relative-gravity differences and absolute-gravity data were combined using a least-squares network...
