Get started
Build CMIP6 output file index
- The first step is to build CMIP6 experiment output file index based
on queries using ESGF search RESTful API
# set directory to store files
options(epwshiftr.dir = tempdir())
options(epwshiftr.verbose = TRUE)
# get CMIP6 data nodes
(nodes <- get_data_node())

Manage CMIP6 output files
-
You have to download CMIP6 output file by yourself using your
preferable methods or tools. The download url can be found in the
file_url column in the index.
-
After you have downloaded CMIP6 output files of interest, you can
use suumary_database() to get a summary on files downloaded
against the CMIP6 output file index.
-
This step is necessary as it map the loaded files against index so
that epwshiftr knows which case is complete and can be used for the
next step.
# Summary downloaded file by GCM and variable, use the latest downloaded file if
# multiple matches are detected and save matched information into the index file
sm <- summary_database(tempdir(), by = c("source", "variable"), mult = "latest", update = TRUE)
#> 24 NetCDF files found.
#> Data file index updated and saved to '/tmp/RtmpDtbJVc/cmip6_index.csv'

Extract CMIP6 output data
- With previous step, now we can match coordinates of an EPW in the
CMIP6 output file
epw <- file.path(eplusr::eplus_config(8.8)$dir, "WeatherData/USA_CA_San.Francisco.Intl.AP.724940_TMY3.epw")
# match any coordinates with absolute distance less than 1 degree
coord <- match_coord(epw, threshold = list(lon = 1, lat = 1), max_num = 1)
#> Start to match coordinates...

Create future EPW files
- Once we get the morphed data using
morphing_epw(), we can now
create future EPW files using future_epw()
# create future EPWs grouped by GCM, experiment ID, interval (year)
epws <- future_epw(morphed, by = c("source", "experiment", "interval"),
dir = tempdir(), separate = TRUE, overwrite = TRUE

Build CMIP6 output file index
- The first step is to build CMIP6 experiment output file index based on queries using ESGF search RESTful API
# set directory to store files
options(epwshiftr.dir = tempdir())
options(epwshiftr.verbose = TRUE)
# get CMIP6 data nodes

Manage CMIP6 output files
-
You have to download CMIP6 output file by yourself using your preferable methods or tools. The download url can be found in the
file_urlcolumn in the index. -
After you have downloaded CMIP6 output files of interest, you can use
suumary_database()to get a summary on files downloaded against the CMIP6 output file index. -
This step is necessary as it map the loaded files against index so that epwshiftr knows which case is complete and can be used for the next step.
# Summary downloaded file by GCM and variable, use the latest downloaded file if
# multiple matches are detected and save matched information into the index file
sm <- summary_database(tempdir(), by = c("source", "variable"), mult = "latest", update = TRUE)
#> 24 NetCDF files found.
#> Data file index updated and saved to '/tmp/RtmpDtbJVc/cmip6_index.csv'

Extract CMIP6 output data
- With previous step, now we can match coordinates of an EPW in the CMIP6 output file
epw <- file.path(eplusr::eplus_config(8.8)$dir, "WeatherData/USA_CA_San.Francisco.Intl.AP.724940_TMY3.epw")
# match any coordinates with absolute distance less than 1 degree

Create future EPW files
- Once we get the morphed data using
morphing_epw(), we can now create future EPW files usingfuture_epw()
# create future EPWs grouped by GCM, experiment ID, interval (year)
epws <- future_epw(morphed, by = c("source", "experiment", "interval"),
dir = tempdir(), separate = TRUE, overwrite = TRUE
)
#> Warning: Empty morphed data found for variables listed below. Original data from EPW will be used:
