The WWDL40 TTAAii Data Designators decode as: T1 (W): Warnings T1T2 (WW): Warnings and weather summary A1A2 (DL): Germany (Remarks from Volume-C: WARNING)

These data are generated by combining satellite-based and surface-measured data of the surface irradiance (global radiation) and the sunshine duration. The associated algorithms have been developed within the DUETT-project and are continuously adjusted and improved. Gridded data (EPSG-3034 projection, Germany) of the surface irradiance and the sunshine duration are generated with a spatial resolution of 2 km and a temporal resolution of 1 hour (average / sum for synoptic hours, ending at minute 50). The data set is separated into two parts: the directory ./{parameter}/recent/ contains the latest data; in the directory ./{parameter}/historical/ older data are archived.

The FODL43 TTAAii Data Designators decode as: T1 (F): Forecast T1T2 (FO): Guidance A1A2 (DL): Germany (The bulletin collects reports from stations: 10637;Frankfurt/Main;EDZF;) (Remarks from Volume-C: TAF-Guidance EDDF (K-ATM MET Guidance))

These data are generated by combining satellite-based and surface-measured data of the surface irradiance (global radiation) and the sunshine duration. The associated algorithms have been developed within the DUETT-project and are continuously adjusted and improved. Gridded data (EPSG-3035 projection, Germany) of the surface irradiance and the sunshine duration are generated with a spatial resolution of 1 km and a temporal resolution of 1 hour (average / sum for synoptic hours, ending at minute 50). The data set is separated into two parts: the directory ./{parameter}/recent/ contains the latest data; in the directory ./{parameter}/historical/ older data are archived.

Based on the DUETT gridded data, additional point data is determined at the coordinates of 576 measurement sites of DWD. These pseudo station data are extracted from the gridded data using a simple ‘nearest neighbour’ assignment and are optimized by a subsequent topography correction. This correction is performed using high-resolution topographic data and it primarily captures the possible blocking of direct solar radiation by surrounding mountains. Associated uncertainties are also determined from the gridded data using a ‘nearest neighbour’ assignment and are not subject to any further adjustment in the current program version. The data set is separated into two parts: the directory ./{parameter}/recent/ contains the latest data; in the directory ./{parameter}/historical/ older data are archived.

These data originate from the stations of the DWD as well as legally and qualitatively equivalent partner networks. Up to and including the complete previous year of the edition date, the data have finally passed through quality control and have been versioned. For more recent data, quality control has not yet been completed. All times are in UTC. According to the SYNOP convention, the hour hh denotes the measurement of hh-10min (so UTC11 denotes the time UTC10:50).

These data originate from the stations of the DWD and legally as well as qualitatively equal partner network stations. Extensive station metadata, such as station relocations, instrument changes, reference time changes, algorithm changes or operator information are included. The dataset is divided into a versioned part with completed quality check, in the directory ./historical/. And a part for which the quality check has not yet been completed, in the directory ./recent/. The folder ./timeseries_overview/ contains information about long time series.
