Data#
To use DWDRadarRequest, you have to provide a RadarParameter,
which designates the type of radar data you want to obtain. There is
radar data available at different locations within the DWD data repository:
For RADOLAN_CDC-data, the time resolution parameter (either hourly or daily)
must be specified.
The date_times (list of datetimes or strings) or a start_date
and end_date parameters can optionally be specified to obtain data
from specific points in time.
For RADOLAN_CDC-data, datetimes are rounded to HH:50min, as the
data is packaged for this minute step.
This is an example on how to acquire RADOLAN_CDC data using
wetterdienst and process it using wradlib.
For more examples, please have a look at examples/provider/dwd/radar.
