DWD CDC Agent

The German weather service "Deutscher Wetterdienst" (DWD) Climatic Data Center (CDC) Agent is a data loading agent available in EQuIS Live that may be used to load weather data from Germany's DWD CDC FTP site.
Before using the DWD CDC Agent, add one or more stations to the DT_LOGGER table:
1.Execute the equis.get_ids stored procedure to get a new LOGGER_ID, or add the station (DT_LOGGER row) in EQuIS Professional.
2.Set LIVE_DATA_SOURCE to DWD-CDC.
3.Set LOGGER_CODE to a station ID. You can search for a station ID here (e.g., 430 for the Berlin-Tegel station).
4.Set STATUS_FLAG to 'A' to activate the logger.
The DWD CDC Agent or Historical Data Loader can be run as a scheduled EQuIS Information Agent (EIA), at the desired frequency, to automatically load data as often as needed.
The DWD CDC Agent or Historical Data Loader can also be run in EQuIS Professional or Enterprise (using the EZView widget) to load the data manually, without having to schedule an EIA.
The DWD CDC Agent will load data for all loggers with LIVE_DATA_SOURCE set to DWD-CDC. The report gets recent hourly values for air temperature, air pressure, wind speed, and wind direction.
When the report is run initially, the agent will retrieve values from a logger's site (DT_LOGGER.LOGGER_CODE) for the past one month. If data has been previously loaded for that logger, the agent will request data from the logger's most recent date (in DT_LOGGER_DATUM.DATUM_UTC_DT) until today's date.
The DWD CDC Historical Data Loader allows you to select the loggers and date range, though it is limited to the past 500 days. It has the following input parameters:
•Logger(s) – Select the stations for which you want to load data. If you do not select any stations, the agent will load data for all DWD CDC stations.
•Date Range – Select a date range, choose from recent, period, or start and end dates. The recent option works the same way as the DWD CDC Agent. If you select the period option, you must enter a period in ISO-8601 duration format. If you select the start and end dates option, you must select start and end dates.
