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 theclimatological 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

Climatological reference stations

To avoid wrong interpretation which is caused in the automatic measurements

Conventional measurements for 10 years 3 measurement per day: 06:30, 13:30 and

20:30 UTC 11 stations are selected, each is

representative for a special area of Germany

To improve methods for homogenization of climate time series and data generation Brocken: Brocken:

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
