writeSim2netCDF: A function to write netCDF-files

In ProfoundData: Downloading and Exploring Data from the PROFOUND Database

Description

This function transforms simulation results into netCDF files following the ISIMIP2 protocol

Usage

writeSim2netCDF(
  df,
  comment1 = NA,
  comment2 = NA,
  institution = "PIK",
  contact = "[e-mail]",
  modelname = "formind",
  GCM = "hadgem",
  RCP = "rcp85",
  ses = "nat",
  ss = "co2const",
  region = "Kroof",
  start = "1980",
  folder = "ISI-MIP"
)

Arguments

df	A data.frame containing in the first three columns longitude latitude and time. These columns are followed by columns containing the output variables. The columns have to be named with the output variable name as required by the 2B protocol. See table 21.
comment1	Optional comment regarding your simulation
comment2	Optional comment regarding your simulation
institution	Your institution
contact	Your mail address
modelname	The name of the used forest model
GCM	The climate model which created the used climate time series
RCP	The RCP scenario
ses	The scenario describing forest management. UMsoc equals the "nat" settings and histsoc and 2005soc equal the "man" settings in the ISIMIP2a protocol. Default value: "nat".
ss	"co2" for all experiments other than the sensitivity experiments for which 2005co2 is explicitly written. Note: even models in which CO2 has no effect should use the co2 identifier relevant to the experiment. Default value: "co2const".
region	the region or site of the simulation
start	the start year of the simulation. Default value: 1980.
folder	The folder in which all netCDF files will be written

Details

The function transforms your simulation output data frame into several netCDF -files and writes them into the indicated folder using the naming convention of the ISIMIP2(B)-protocol (https://www.isimip.org/protocol/). Units and long names of variables (table 21) will be created automatically.

Examples

# Produce sample data 
df <- data.frame(lat = rep(20, 10),
                 lon = rep(30, 10),
                 time = seq(1920, 2010, 10),
                 dbh_total = c(10:19),
                 nee_total = rnorm(10, -0.5, 0.25),
                 evap = rnorm(10, 0.001, 0.0001),
                 cwood_fasy = seq(40, 85, 5))

# Convert multi-variable data.frame into single-variable netCDFs using ISIMIP naming conventions
writeSim2netCDF(df = df,
                comment1 = NA,
                comment2 = NA,
                institution = 'PIK',
                contact = '[e-mail]',
                modelname = "formind",
                GCM = "hadgem",
                RCP = "rcp85",
                ses = "nat",
                ss = "co2const",
                region = "Kroof",
                start = '1920',
                folder = tempdir())
