5. Overview of national third-party networks
Precipitation Network
rain (1min; 10 min)
rain (1h; 6h; 24h)
snow
water equivalent of snow (man. 24h; auto. 10min)
Agricultural Network
air temperature in 2m
soil temperature in 5 cm
soil temperature in 20 cm
soil temperature in 50 cm
relative humidity in 2m in %
wind-speed in 2.5m
global radiation
rain
gust
Road Network
air temperature in 4m
dew point
road-surface temperature
soil temperature

atmospheric pressure
wind-speed + -direction
Wind Network
wind-speed + -direction in several levels
These networks differ a lot in parameters, sensors, frequency, quality and transfer

6. Precipitation-network-data
Technical Standards of Fed.State Precipitation-Networks
Site-Building according to WMO-Standards monitored by DWD
Sensors are certified by DWD and are fully meeting the WMO requirements
Data-Transmission (measure-/deliver-sequence) according to DWD-Standards
Data-Formats are specified by DWD (BUFR, XML)

(name, location, sensors, etc.)
DWD: definition of archive,
granting of index-numbers for all stations 2
coordination of data-formats,
measuring-frequence, data-transfer, etc.
hourly exchange of measured-data
Fed.State -> DWD measured-data
DWD -> Fed.State measured-data (raw / reviewed),
forecast-products (SNOW, RADOLAN, etc.) 3

16. How it should work in the future ..
today
future
file-based Data-exchange
Several Data-Formats via FTP
Special File-Distribution-System
file-based Data-processing
A lot of Data-konversions and distribution of Files before DB-Storage
DB-based Data-exchange
DB-input-output-Format in XML
DB is read-/writable from outside via DWD-API
DB-based Data-processing
No file-based Data-konversions; needed Files/Reports are created by DB-export.
