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)
