National Meteorological Service 


Its basic activities are: 

  • Operating a terrestrial, high-altitude, remote-sensing meteorological and other background air pollutants measuring (in general and specialized way), detection, telecommunication and data processing system in accordance with international obligations.

  • The meteorological base data is being stored and archived structurally in the database by the organisation.

  • Based on the meteorological base data, and data calculations, analysis received under international agreements, – including the climatological activities – the organisation prepares further calculations, analyses, and meteorological forecasts, and in accordance with national agreements, it exchanges data and results with international organisations.

  • The organisation as the operator of the Reference Centre of Air-quality Management (Levegőtisztaság-védelmi Referencia Központ, LRK in Hungarian), carries out quality management, data centre tasks and type-approval testing of gas analyser and dust measuring devices suitable for continuous measuring, for the National Air Pollution Measuring Network (Országos Légszennyezettségi Mérőhálózat).

  • It prepares data on air quality condition and carries out emission inventory regarding greenhouse gases and air pollutants, to fulfil its reporting obligations under international agreements.

Actions taken as part of the HungAIRy LIFE integrated project


Developing an improved emission database as input data for air quality modelling

In accordance with the latest Air Quality Directive, the inclusion of modelling among the evaluation and management tools of air quality is required, therefore the OMSZ intends to install an air quality modelling system. The modelling system under development, includes a regional-urban and a local components, both of which are required for scientific emission data. The aim of the action is to establish an improved emission database that serves as an input for various components of the air quality modelling chain. The regional-urban modelling requires raster emission data, both in the case of regional modelling covering the whole territory of Hungary (with a resolution of 25 km) and with a magnified covering of the cities (with e resolution of approximately of 4 km). VITO (Flemish Institute for Technological Research) assists the action in capacity building to collect emission data from different databases (regional scale) and in increasing the resolution of emission data based on indirect data (urban scale). Each municipality is responsible for collecting indirect data.

During the elaboration of local emission register, the currently available local emission registers will be reviewed first, and then a bottom-up approach will be adopted to determine public emissions in detail. After preparation, a detailed public emission database will be developed, then road traffic data will be collected to model the emission from road traffic.

Preparing the installation of measuring stations 

As part of the action, we will install two, continuously operating measuring stations in Békéscsaba and Kaposvár. The OMSZ will prepare the development of the “K-puszta” measuring station operated by the OMSZ On the continuously operating measuring stations, automatic measuring devices will be used. As the first step of the preparation, appropriate locations for the stations will be identified. During the preparation process, besides the preparation of the infrastructure, the assignment and training of the operating staff will be ensured by the parties involved.

High-resolution air quality evaluation device covered the whole territory of Hungary

During the action, an air quality evaluation system will be developed, as Hungarian authorities have no decision-support toolkit on local basis for making informed decisions under the region’s action plan. The OMSZ using CHIMERE chemical transport model, which can generate air quality data with resolution of 0,1° x 0,1°. But this resolution is not sufficient to urban air pollution hotspots. We will use and make available for the Hungarian authorities the ATMOSYS decision-support and analytical instruments of VITO in the first and second stages of the process. The modelling chain of ATMOSYS analysing and designing program will be adopted to the Hungarian conditions (by entering/recording OMSZ CHIMERE data and local input data) to prepare air quality maps of Hungary with higher resolution magnifications and the selected hotspot areas. 

Installing measuring stations

The aim is the continuous monitoring of air quality in Békéscsaba and Kaposvár. The measuring stations will be installed as an integrated part of automatic measuring network of the National Air Pollution Measuring Network (Országos Légszennyezettségi Mérőhálózat, OLM). Measured components of air pollution are the follows: ozone, nitrogen oxides (NO, NO2, NOx), sulphur dioxide, carbon monoxide, airborne dust PM10 fraction (continuous measurement), airborne dust PM2,5 fraction (continuous measurement), airborne dust PM10/PM2,5/PM1,0 fraction sampling to phased composition measuring with low flow rate samplers (low flow sampler, LFS). The measured meteorological parameters are the follows: barometric pressure, wind direction, wind speed, temperature and humidity.

The K-puszta background measuring station carries out standard background air quality measurements. To provide the measured background air pollution values comparable to the urban situation. The station will be equipped with a standard calibration system, therefore the K-puszta station will be served as a reference background station.

Further activities in which OMSZ participated:

  • Employing eco-manager

  • Participating in awareness raising
