Galloway, D.L., 2019, 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: U.S. Geological Survey data release, https://doi.org/10.5066/P9ON8U5U.

Summary

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 [...]

Purpose

Because water-level responses to barometric-pressure variations (atmospheric loading) and solid Earth tides can potentially mask subtle water-level responses to other hydrologic stresses, it is useful to filter raw water-level records for atmospheric-loading and Earth-tide effects. The unfiltered groundwater-level records for the three USGS monitoring wells [28A-25-1 (373904118570701); 28A-25-2 (373904118570702); and 14A-25-1 (373927118571701)] are strongly influenced by changes in barometric pressure (atmospheric loading). Unfiltered water levels in one of the wells (14A-25-1) are moderately-to-weakly influenced by the solid Earth tide. For monitor wells 28A-25-1, 28A-25-2 and 14A-25-1, digital filters were developed to remove the water-level responses to atmospheric loading from the raw water-level records. Computed water-level responses to Earth tides in well 14A-25-1 were digitally filtered from the parsed water-level time series prior to computing the atmospheric-loading frequency responses for that well. The computation of the frequency response functions and the development of the digital Earth tide and atmospheric loading filters are described in Appendix 2 of the associated publication (https://doi.org/10.3133/ofr20191063).
