Data.UVic.model: UVic ESCM climate model ensemble output

In stilt: Separable Gaussian Process Interpolation (Emulation)

Description

Temperature anomaly output from UVic ESCM climate model ensemble

Usage

data(Data.UVic.model)

Format

The format is a list containing five elements:

$t

Time vector for model output: (1850, 1851, ... 2009)

$tunits

Time units = "Year"

$out

[1:160, 1:250] matrix of UVic ESCM temperature output. [row, col] = [time, run index]. The parameter settings corresponding to runs in columns of $out are in the $par element of Data.UVic.par

$outname

Output name = "Temperature Anomaly from 1850-1899"

$outunits

Output units = "[K]"

Details

The ensemble was run by Roman Olson at Penn State University. The ensemble varies key parameters that affect decadal- and century-scale climate response to external climate forcings: vertical ocean diffusivity, climate sensitivity, and anthropogenic sulfate aerosol scaling factor.

Examples

# Fit an emulator to the UVic ESCM ensemble data using all parameter and
#time covariates

data(Data.UVic.par)
## Not run: emulator(Data.UVic.par, Data.UVic.model, c(TRUE, TRUE, TRUE), TRUE, 1, 1)
