Kennedy, J.R., Kahler, L.M., Pool, D.R., 2019, Repeat microgravity data from the Big Chino Subbasin, 2001-2017, Yavapai County, Arizona: U.S. Geological Survey data release,


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 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 [...]
