Quality Control of Observations


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


Non real-time Quality Control

Some 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


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


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


Observation network will

be 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


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
