proxysnr: An R package to separate the common signal from local noise in climate proxy records using spectral analyses

Thomas Münch

Laepple, Thomas; Dolman, Andrew M.

proxysnr implements a method working in the spectral domain to separate the common signal from the local noise as recorded by a spatial network of climate proxy records, which yields an estimate of the timescale dependence of the proxy signal-to-noise ratio (SNR). The implemented method includes the correction of relevant estimated power spectral densities for the loss in spectral power by two effects: (1) time uncertainty in the case of layer-counted record chronologies and (2) water vapour diffusion through the open-porous firn in the case of stable isotope records from firn and ice cores.

This version of the R package was released along with the publication Münch and Laepple, Clim. Past, 2018.
