This function allows to download data from WorldClim v.2.1 (https://www.worldclim.org/data/index.html) considering multiple GCMs, time periods and SSPs.
Usage
WorldClim_data(path = NULL,
period = "current",
variable = "bioc",
year = "2090",
gcm = "mi",
ssp = "585",
resolution = 10)Arguments
- path
Directory path to save downloads.
- period
Can be "current" or "future".
- variable
Allows to specify which variables you want to retrieve Possible entries are: "tmax","tmin","prec" and/or "bioc".
- year
Specify the year you want to retrieve data. Possible entries are: "2030", "2050", "2070" and/or "2090". You can use a vector to provide more than one entry.
- gcm
GCMs to be considered in future scenarios. You can use a vector to provide more than one entry.

SSPs for future data. Possible entries are: "126", "245", "370" and/or "585". You can use a vector to provide more than one entry.
- resolution
You can select one resolution from the following alternatives: 10, 5, 2.5 OR 30.
Value
If data is not downloaded, the function downloads the data and has no return value. If
the data is downloaded, it imports the data as a stack.
Details
This function will create a folder entitled "input_data/WorldClim_data_current" or "input_data/WorldClim_data_future". All the data downloaded will be stored in this folder. Note that, despite being possible to retrieve a lot of data at once, it is not recommended to do so, since the data is very heavy.
Examples
# \donttest{
# download data from multiple periods:
year <- c("2050", "2090")
WorldClim_data(period = "future",
variable = "bioc",
year = year,
gcm = "mi",
ssp = "126",
resolution = 10)
#> [1] "mi_ssp126_10_2050"
#> [1] "mi_ssp126_10_2090"
#> list()
# download data from one specific period
WorldClim_data(period = "future",
variable = "bioc",
year = "2070",
gcm = "mi",
ssp = "585",
resolution = 10)
#> [1] "mi_ssp585_10_2070"
