abstract
2018 Hungarian Meteorological Service. All Rights Reserved. AirGIS and the semi-parametrized Operational Street Pollution Model (OSPM) have been frequently used across the globe to assess local or street-scale air pollution. Recent developments in OSPM and new technological advances in geospatial tools have led towards an inception of a substantially revised version of the AirGIS exposure modelling system (AirGIS 2). The new prototype system uses open source software as the geospatial programming tools in a PostgreSQL/PostGIS database in conjunction with R scripts for pre-processing and post-processing of the datasets. This study provides an overview of the re-development, initial testing phase together with strengths, limitations and future prospects of the new system. AirGIS has been re-evaluated against various long-term and short-term field measurements. The present study gives a brief overview of the evaluation and shows the main results and conclusions derived from this validation.
