Additional Stations operated by DWD and Partners è 1779 Voluntary Stations (climate; wind; precip), 1534 reporting online (24/1 reports per day) Ship-based: è 540 Voluntary Observing Ships (VOS) è 19 Ship AWS (24 reports/day) Last but not least …: è 1200 Phenological stations (approx) (observing plants) è 1700 Partner stations (approx) (motorways, fed. states, wind-energy, (nuclear) power-plants, universities, military) TI 21 B - 11/2016 – TECO Guangzhou 4

Overview of national third-party networks Precipitation Network • rain (1 min; 10 min) • rain (1 h; 6 h; 24 h) • snow • water equivalent of snow (man. 24 h; auto. 10 min) Atmospheric Network • air temperature • • • humidity atmospheric pressure wind-speed + -direction Agricultural Network • air temperature in 2 m • soil temperature in 5 cm • soil temperature in 20 cm • soil temperature in 50 cm • relative humidity in 2 m in % • wind-speed in 2. 5 m • global radiation • rain • gust Road Network • air temperature in 4 m • dew point • road-surface temperature • soil temperature • wind-speed in 4 m • gust • rain • road-condition Wind Network • wind-speed + -direction in several levels These networks differ a lot in parameters, sensors, frequency, quality and transfer TI 21 B - 11/2016 – TECO Guangzhou 5

Precipitation-network-data Technical Standards of Fed. State Precipitation. Networks è Site-Building according to WMO-Standards monitored by DWD è Sensors are certified by DWD and are fully meeting the WMO requirements è Data-Transmission (measure-/deliver-sequence) according to DWD-Standards è Data-Formats are specified by DWD (BUFR, XML) TI 21 B - 11/2016 – TECO Guangzhou 6
