Summary

 

The project focuses on development of institutional strengthening to be able to carry out national air emission inventories in Latvia based on the European CORINAIR methodology. The present report describes the link between emission inventories and air quality modelling to ensure that the new national air emission inventory is able to take into account the data requirements of air quality models.

 

The first part of the report illustrates how emission data can be used in air quality assessment on different geographic scales (regional, urban, street and individual industrial sources) and pinpoints what supplementary data is required to be able to utilise emission data for air quality modelling. An assessment has been carried out of the parameters required for air quality modelling and compared to existing emission data to be able to specify supplementary parameters. These supplementary parameters should be collected as part of the national emission inventory with special attention to point sources. A procedure for collection of supplementary data has briefly been discussed.

 

To improve future air quality assessment based on modelling it is important that the Regional Environmental Boards/Latvian Environmental Agency (REB/LEA) builds up a database that contains necessary parameters for stationary and other sources needed for AQ modelling. In the process of building a national emission inventories based on CORINAIR, REB/LEA should supplement their existing da-tabase with necessary information needed for air quality modelling and make such data are available for air quality modelling purposes.
