Download WorldClim v.2.1 bioclimatic data
Description
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.
| |||||||||||||||||||||||||||||||||||||||||||||||||||||
ssp |
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. |
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.
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
.

Examples
# download data from multiple periods:
year <- c("2050", "2090")
WorldClim_data(period = "future",
variable = "bioc",
year = year,
gcm = "mi",
ssp = "126",
resolution = 10)
# download data from one specific period
WorldClim_data(period = "future",
variable = "bioc",
year = "2070",
gcm = "mi",
ssp = "585",
resolution = 10)
