get.dwd.ftp.url: Obtain URLs to the FTP server

In theGreatWhiteShark/dwd2r: Automated download and formatting of the data provided by the German weather service (DWD)

Description

Interactive function to extract the download URLs of the FTP server of the DWD

Usage

get.dwd.ftp.url(batch.choices = NULL)

Arguments

batch.choices

Numerical vector containing the numbers, which correspond to the choices in the interactive mode. If NULL, the choices will be selected interactively. Default = NULL.

Details

Since there is A LOT of different data provided by the German weather service (DWD), it makes no sense to specify them all using input arguments to this function. Instead, the user will be guided interactively through the different data sources and specifies the data she want using the inputs at the prompt. If you prefer to run the function non-interactive, you can use the batch.choices argument and supply a vector of numbers corresponding to your choices.

As another option, you can use the cat.dwd.ftp.url function, which returns a vector containing all download URLs. This vector can then be manipulated using e.g. the grep command.

Since there is a lot of different set of data, it is also not possible to provide documentation for the individual data sources. Please see the ftp://ftp-cdc.dwd.de/pub/CDC/ FTP server for further details.

Before using the data of the DWD, be sure you read its ftp://ftp-cdc.dwd.de/pub/CDC/Terms_of_use.pdf!

Value

List containing to two elements

• data - A character vector containing one or more URLs pointing to the different data folders on the FTP servers of the DWD

• meta - A character vector pointing to the folder containing the meta data. Or NULL if there is no distinct folder and the meta data is contained in the folders present in the data URLs
