Abteilung Messnetze und Daten
Need for modernizing the ‚voluntary Observer network‘ for climatology/hydrology :
by
using new measurement- and information-technology and
redesigning the net (locations, numbers, equipment of stations):
achieve
- automizing the readings of instruments
- prompting eye observations into electronic data processing

Abteilung Messnetze und Daten
Other objectives of the new network
- Improve data quality: same level as data from synoptical stations
- fast availability of data
- central archiving of data
- remote monitoring and remote configuring of stations
TECO-2006, 4 dec 2006, Geneva
Abteilung Messnetze und Daten
Building the network: working routines
Activities at the site:
- searching for station locations- granting contract with site owner- pre-installation of the measurem. area- provision of ISDN connection- installation of the measurement system- starting up and instruction
Providing hardware & software for station & network
- fixing user requirements- writing specifications- procurement procedures- acceptance tests of prototypes- tests of series production
- system modifications

Observer‘s activities
send messages at fixed time of the day: - precip. height (control measurem.), snow depth,- state of the ground- estimation of wind, cloudiness, visibility
send messages of continuous weather with general time indications or exact time intervals:- falling precipitation: y/n, type, intensity, frequency- deposited precipitation: dew, rime, slippery ice/snow- extraordinary weather appearances: electrical / optical phenomena, turbidity, extreme wind,...
Display data, messages and system information
Simple maintenance of sensors, set sensor status

Features of the station network center
- Calling data sets of time averages / sums of 1 min, 10 min, 1 h, 24 h of met. quantities Calling intervals: 1 h for ‚S‘ and ‚W‘ stations, 24 h for ‚N‘ stations, other intervals: configurable, and immediate calls - Receiving data on: incidents of exceeding thresholds of wind or precip. or certain weather penomena, system errors
- Network monitoring from any site of DWD intranet: software update, configuration of station groups, survey of individual stations
- Central data base
- Backup System
- Provisions for IT safety

Quality assurance of data
1. Provisions at the station: - Range check - Variability check - Generation of a quality byte for each value sent to the network center - Alarm generation
2. Provisions at the network center - Off-line quality control and monitoring system (see Spengler, R., Proc. TECO2002, Dibbern, J., Proc. TECO2005)

System modification and maintenance
From the view of resources : expected long lifetime of the network (but no more support from system provider)
new requirementsfrom users, remove faults
modifications: who can do it ?
Station hardware:- components on store- test new marketable components and implement existing software
Network center:merging with synopt. network center in preparation
Station software:
Developers ? (if at hand)
DWD staff: keeps system knowledge

Final remarks
Benefits of the new network :
Improvement of climatological / hydrological data- less expenditure for observers: less errors- fast availability, time resolution of data- increased quality by on-line algorithms, monitoring programs, new hardware
Profits for additional users: availability of actual data- AMDA III / S data: complement the synopical station network- AMDA III / N data: useful for flood modelling/forecasting- AMDA III / W data: warning management
