Key Area: Integrated Quality Management
Quality control
 quality control of data
 step 1:
automated quality control at station (realtime)
 step 2:
automated quality control at central database (realtime);
semi-automated quality control in central office (near realtime)
(software tool „QualiMET“ - central version)
 Monitoring 24/7 since 2012/01
 step 3:
semi-automated quality control at DWD‘s regional network
groups (software tool „QualiMET“; data processing after
max. 10 days)
 step 4:
semi-automated quality control of the values at the
climatological observation times in central office
(data processing within 2 years)
 each dataset will be flagged with a quality level
 each value will be flagged with different quality information

Results
 WIGOS is part of the current DWD strategy 2014 - 2020
 Implementation of the ten WIGOS key areas is mainly realized in DWD
 DWD will be the national integrator for meteorological observations and
meta data
 Standardization of observations is realized in all meteorological
networks of DWD (baseline network, secondary (= voluntary) network)
 European standardization in marine network started in last year
 Integration of additional partnership networks is planned
