time.uncertainty.tf: Time uncertainty transfer functions

In EarthSystemDiagnostics/proxysnr: Separate Signal and Noise in Climate Proxy Records

Time uncertainty transfer functions

Description

A dataset containing the calculated time uncertainty transfer functions for the DML1, DML2 and WAIS records from Münch and Laepple (2018) based on numerical simulations. The transfer function describes the effect time uncertainty has on the spectrum of the average (in the time domain) of a number of N proxy records.

Usage

time.uncertainty.tf

Format

A named list with the 3 elements dml1, dml2, and wais, where each element is a spectral object:

freq:

the frequency axis in units of 1 / yr,

spec:

the transfer function value at each frequency.

Source

The transfer functions were obtained using ?CalculateTimeUncertaintyTF; see also the respective package vignette("calculate-transfer-functions").
