Description

determine which subfunction to call in readDWD() from the file extension (ext).

Click on the type for the subfunction documentation, e.g. data for readDWD.data().

type	ext	notes
data	.zip	For regular data at dwdbase.
meta	.txt	For Beschreibung.txt files. For zip files containing station meta information, see readMeta().
multia	[SO]	[SO]: file ends with "Standort.txt" or contains multi_annual. Overrides meta.
stand	[SF]	[SF]: file contains "standard_format". For subdaily/standard_format files.
data	.txt.gz	For data at /CDC/derived_germany/.
pdf	.pdf	only opens file in default viewer.
-------
radar	.gz	For when the file contains a single binary file.
binary	.tar.gz	The common radolan format, as far as I can tell.
raster	.asc.gz	E.g. for seasonal data at gridbase.
nc	.nc.gz	For netcdf files.
asc	.tar	For a file containing asc files.
rklim	YW*.tar	For a file containing bin files.
