Quality Control of Observations
27-30 November 2007, Tarragona, Spain 22HNMS http://www.hnms.gr
Quality Control Methods of Meteorological Observations
Levels of quality control: 1. Real-time2. Non real-time3. Manual
Real-time Quality Control Procedures• 35 MS are connected online to HNMS • First level real-time quality control done at the station
On-site quality control procedures include:• Missing values check • Syntax control• Cross error checking (limit check) Observations: • Are transmitted automatically and stored to an auxiliary database • Data stored permanently after they pass successfully quality control
27-30 November 2007, Tarragona, Spain 23HNMS http://www.hnms.gr
Non real-time Quality ControlSome MS are connected with HNMS by • telex• phone• mail
QC checks at the end of every month for RT and NRT Data include
Range and limit check-based on statistical limits Step check for parameter value changes Internal consistency checks for >= 2 variables
27-30 November 2007, Tarragona, Spain 24HNMS http://www.hnms.gr
Human Quality Control
• HQC: final phase of QC• Examination of erroneous or suspicious data • Based on generated error lists• Correction done by experienced observers• Final data passed HQC successfully stored in a
permanent database

Future Planning
27-30 November 2007, Tarragona, Spain 29HNMS http://www.hnms.gr
In progress
By the end of 2008
• 17 new AWS will be incorporated into
existing network
• 35 stations will be converted to hybrid
(semi-automatic)
• Newly-purchased automated instruments
will replace old meteorological
instruments
• Inventory of data
30HNMS http://www.hnms.gr
- 36 existing stations will be connected to existing
telecommunication system
- New computer system and software will be installed
- METSTATION, already running on 35 sites, will be
extended
- Small databases will be developed at stations
- Improvement of quality control procedures (1st level RT QC
at station level)
- Measurement data will be inputted automatically to HNMS
database
- Upgrading of existing database
- Climatological database will be developed
- A web-based interface will be developed with generation of
Climatological data reports capabilities
Plans for2008-2009
27-30 November 2007, Tarragona, Spain 32HNMS http://www.hnms.gr
Observation network willbe expanded to include
140 automatic weather stations semi-automatic (hybrid) only stations
use automatic meteorological instruments New weather stations will be established for
wind radiation
measurements
By 2012
27-30 November 2007, Tarragona, Spain 33HNMS http://www.hnms.gr
What we need• Help in data rescue techniques
– Tested systems did yield good results– 25% success rate-scanned documents/Papyrus Software– perhaps focus in preserving images of data records in picture (jpg)
format?• Participate in specialized workgroups to gain know-how• Allocate specialized personnel for data rescue activities? (Data
inventory activities underway)• Establish a Data Resque Department? (Already have a Quality
Control Department just for verification of weather forecasts)• Training and international collaborations• Ideas
