Download WorldClim v.2.1 bioclimatic data

Source: R/WorldClim_data.R
WorldClim_data.Rd

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.

Value

If data is not downloaded, the function downloads the data and has no return value.

Details

This function will create a folder. 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.
