• r_r0 (int or float or None or pd.Series or list, optional) – Should the ET timeserie contain a column with R_R0. If None, then no column is added. If int, then a R/R0 column is appended with this number as standard value. If list of int or floats, then the list should have the same length as the ET-timeserie and is appanded to the Timeserie. If pd.Series, then the index should be a timestamp index. The serie is then joined to the ET timeserie. The default is 1.

Raises

Warning – If there are NAs in the timeseries or the period got changed.

create_ts(dir, period=(None, None), kinds='best', stids='all', agg_to='10 min', r_r0=None, split_date=False, nas_allowed=True, add_na_share=False)

Download and create the weather tables as csv files.

Parameters

• dir (path-like object) – The directory where to save the tables. If the directory is a ZipFile, then the output will get zipped into this.

• period (TimestampPeriod like object, optional) – The period for which to get the timeseries. If (None, None) is entered, then the maximal possible period is computed. The default is (None, None)

• kinds (str or list of str) – The data kind to look for filled period. Must be a column in the timeseries DB. Must be one of “raw”, “qc”, “filled”, “adj”. If “best” is given, then depending on the parameter of the station the best kind is selected. For Precipitation this is “corr” and for the other this is “filled”. For the precipitation also “qn” and “corr” are valid.

• stids (string or list of int, optional) – The Stations for which to compute. Can either be “all”, for all possible stations or a list with the Station IDs. The default is “all”.

• agg_to (str, optional) – To what aggregation level should the timeseries get aggregated to. The minimum aggregation for Temperatur and ET is daily and for the precipitation it is 10 minutes. If a smaller aggregation is selected the minimum possible aggregation for the respective parameter is returned. So if 10 minutes is selected, than precipitation is returned in 10 minuets and T and ET as daily. The default is “10 min”.

• r_r0 (int or float or None or pd.Series or list, optional) – Should the ET timeserie contain a column with R/R0. If None, then no column is added. If int, then a R/R0 column is appended with this number as standard value. If list of int or floats, then the list should have the same length as the ET-timeserie and is appended to the Timeserie. If pd.Series, then the index should be a timestamp index. The series is then joined to the ET timeserie. The default is None.

• split_date (bool, optional) – Should the timestamp get splitted into parts, so one column for year, one for month etc.? If False the timestamp is saved in one column as string.

• nas_allowed (bool, optional) – Should NAs be allowed? If True, then the maximum possible period is returned, even if there are NAs in the timeserie. If False, then the minimal filled period is returned. The default is True.

• add_na_share (bool, optional) – Should one or several columns be added to the Dataframe with the share of NAs in the data. This is especially important, when the stations data get aggregated, because the aggregation doesn’t make sense if there are a lot of NAs in the original data. If True, one column per asked kind is added with the respective share of NAs, if the aggregation step is not the smallest. The “kind”_na_share column is in percentage. The default is False.
