Check climatic data server

Description

Checks that the online climatic data server is available and working correctly.

Usage

check_server(
  climatic_var = NULL,
  year = NULL,
  version = "last",
  verbose = TRUE,
  time_unit = "day"
)

Arguments

climatic_var

Optional. One of "Prcp", "Tmin", or "Tmax".

year

Optional. Year between 1950 and the latest year available on the server. Use get_periods() to obtain the available data versions and years available.

version

Character. Climatic data version. Either "last" (default) or "4" (version 4).

verbose

Logical. If TRUE, prints diagnostic messages; otherwise, returns only TRUE/FALSE.

time_unit

Character. One of "day" , "month" or "year".

Value

TRUE if the server is available; FALSE otherwise.

Get annual data for multiple climatic variables

Description

Extract annual climate data (temperature and precipitation) for a given set of points or polygons within Europe.

Usage

get_annual_climate(
  coords = NULL,
  climatic_var = "Prcp",
  period = NULL,
  output = "df",
  check_connection = FALSE
)

Arguments

coords

A matrix, data.frame, tibble::tbl_df-class, sf::sf(), or terra::SpatVector() object containing point or polygon coordinates in decimal degrees (lonlat/geographic format, EPSG 4326). Longitude must fall between -40.5 and 75.5 degrees, and latitude between 25.5 and 75.5 degrees. If coords is a matrix, it must have exactly two columns: the first containing longitude and the second containing latitude. If coords is a data.frame or a tbl_df, it must contain at least two columns called lon and lat with longitude and latitude coordinates, respectively.

climatic_var

Character. Climate variables to download ("Tmax", "Tmin", "Tavg", or "Prcp"). Various elements can be concatenated in the vector.

period

Numbers representing years between 1950 and the latest year available. To specify a sequence of years use the format 'start:end' (e.g. YYYY:YYYY, see examples). Various elements can be concatenated in the vector (e.g. c(2000:2005, 2010:2015, 2020))

output

Character. Either "df", which returns a data.frame with daily climatic values for each point or polygon, or "raster", which returns terra::SpatRaster() objects (within a list when more than one climatic variable is downloaded).

check_connection

Logical. Check the connection to the server before attempting data download?

Value

Either:

A data.frame (if output = "df")
A list of terra::SpatRaster() object (if output = "raster")

For precipitation, the function returns total (accumulated) precipitation per year. For temperature variables ('Tmin', 'Tmax', 'Tavg') the function returns the average (i.e. the annual average of minimum and maximum daily temperatures, or the average annual temperature).

Get daily data for multiple climatic variables

Description

Extracts daily climatic data (temperature and precipitation) for a given set of points or polygons within Europe.

Usage

get_daily_climate(
  coords = NULL,
  climatic_var = "Prcp",
  period = NULL,
  output = "df",

period

Either numeric vector of years (between 1950 and the latest available year) or character vector of dates in "YYYY-MM-DD" format (to obtain data for specific days). To specify a sequence of years or dates, use the format 'start:end' (e.g. YYYY:YYYY or "YYYY-MM-DD:YYYY-MM-DD", see examples). Multiple dates or years can be concatenated in the vector (e.g. c(2000:2005, 2010:2015, 2020), c("2000-01-01:2000-01-15", "2000-02-01")). Use get_periods() to obtain the available data versions and years available.

output

version

Character. Climate data version. Uses the latest version ("last") by default. Version "4" is also available for reproducibility. See References for details about the climate datasets.

check_connection

Logical. Default is FALSE. If TRUE, checks the connection to the server before attempting to download the data.

Value

Either:

A data.frame (if output = "df")
A terra::SpatRaster() object (if output = "raster")
A list of terra::SpatRaster() objects (if output = "raster" and there is more than one climatic_var).
