Atmospheric-loading frequency response functions and groundwater-levels filtered for the effects of atmospheric loading and solid Earth tides for three monitoring wells near Mammoth Lakes, California, 2015 - 2017.

The data include atmospheric-loading frequency response functions (table 1) and filtered detrended and reconstructed (trends restored) groundwater-levels (tables 2 to 4) computed for selected, parsed time series for three USGS monitoring wells [28A-25-1 (373904118570701); 28A-25-2 (373904118570702); and 14A-25-1 (373927118571701)], and the associated hourly resampled depth-to-water-level and barometric-pressure time-series "pieces" (tables 2 to 4) used to create the parsed series. Digital filters were developed based on the computed water-level response to Earth tides in well 14A-25-1 and barometric pressure in all three wells, and these filters were used to compute the filtered water-level time series in tables 2 and 3 for wells 28A-25-1 and 28A-25-2, respectively, and in table 4 for 14A-25-1. The tables (1-4) and the development of the digital filters and filtering techniques are described in Appendix 2 of the associated publication (https://doi.org/10.3133/ofr20191063).
