fldgen-package: Climate variable field generator with internal variability...

In JGCRI/fldgen: Generate Temperature Fields with Spatial and Temporal Correlation

Description

Provides functions to learn the spatial, temporal, and inter-variable correlation of the variability in an earth system model (ESM) and generate random two-variable fields (e.g. temperature and precipitation) with equivalent properties.

Example

The data used in this example can be found in system.file('extdata', package='fldgen')

library(fldgen) datadir <- system.file('extdata', package='fldgen') infileT <- file.path(datadir, 'tas_annual_esm_rcp_r2i1p1_2006-2100.nc') infileP <- file.path(datadir, 'pr_annual_esm_rcp_r2i1p1_2006-2100.nc') emulator <- trainTP(c(infileT, infileP), tvarname = "tas", tlatvar='lat', tlonvar='lon', tvarconvert_fcn = NULL, pvarname = "pr", platvar='lat', plonvar='lon', pvarconvert_fcn = log) residgrids <- generate.TP.resids(emulator, ngen = 3) fullgrids <- generate.TP.fullgrids(emulator, residgrids, tgav = tgav, tvarunconvert_fcn = NULL, pvarunconvert_fcn = exp, reconstruction_function = pscl_apply)
