Load data from REST API that uses Toar DB V2. Path is: https://toar-data.fz-juelich.de/api/v2/ # todos * [x] get station name * [x] load variables ids * [x] get all variables of station * [x] load data for station * [x] make use of meta data * [x] choose between different `roles` (replacing network parameter) * [x] remove network parameter from MLAir (make it a data handler parameter) * [x] old AIRBASE data is not available in V2 for now: implement module to merge data from v1 and v2 * [x] check for timezone of data, could be that v1 is on local time but v2 in UTC -> v1 always uses UTC without indicating, v2 uses UTC indicated by tz_info * [x] as old and new AIRBASE data will be provided as distinct time series in V2, there should be a module merging these series -> all available series are merged (in case UBA and EEA are given this results in a merge of all UBA and EEA beeing merged, if only UBA is given, only UBA data is merged) # collection of sample links ### station meta data Ask for station meta data https://toar-data.fz-juelich.de/api/v2/stationmeta/?codes=DEBW107 ### variable codes Ask for variable code https://toar-data.fz-juelich.de/api/v2/variables/o3 ### timeseries ids Search for timeseries id with given variable id and station id https://toar-data.fz-juelich.de/api/v2/search/?station_id=88&variable_id=5 or Search for timeseries id with given variable id and station codes https://toar-data.fz-juelich.de/api/v2/search/?codes=DEBW107&variable_id=5 variable name cannot be used in search Both commands could return multiple series, i.e. for UBA and EEA. To select the right series id, the meta data needs to be inspected. ### load timeseries data Load data of this timeseries with https://toar-data.fz-juelich.de/api/v2/data/timeseries/18650?format=csv ### loading aggregated timeseries data To load statistics like dma8eu https://toar-data.fz-juelich.de/statistics/api/v1/?timeseries_id=18650&names=dma8eu&sampling=daily Note that this uses v1 (which still uses the new DB). Multiple statistics can be requested by using a comma separated list `names=dma8eu,max`
