Interactive function to extract the download URLs of the FTP server of the DWD
Numerical vector containing the numbers, which correspond to the choices in the interactive mode. If NULL, the choices will be selected interactively. Default = NULL.
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
function, which returns a vector containing all download
URLs. This vector can then be manipulated using e.g. the grep
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!
