Konverze inventářů z databáze REZZO pro modelování znečištění ovzduší
Liczki, Jitka ; Resler, Jaroslav ; Krč, Pavel ; Eben, Kryštof
The Czech national emission and air pollution sources inventory (REZZO) is a large database covering anthropogenic emissions produced in the Czech Republic. REZZO can be used as emission inputs for advanced air quality models, e.g. CAMx, CMAQ after a conversion that enables SMOKE system. Since SMOKE is developed for US standards it needs some adaptations before using for REZZO. Converted REZZO emissions for point and area sources for a grid with 3km horizontal resolution are presented.

Asimilace satelitních a přízemních dat do modelů kvality ovzduší
Resler, Jaroslav ; Eben, Kryštof ; Juruš, Pavel ; Krč, Pavel
Tropospheric columns of various species retrieved from satellite instruments bring a new quality into data assimilation systems for air quality models. In our experiments we assimilate tropospheric columns of NO2 retrieved from the instruments GOME2 and OMI together with ground-level observations of NO2. The 4DVar method has been used to optimize both initial conditions and suitable parameters of the emission model. A forecast experiment has been performed and the contribution of data assimilation to the one-day-ahead forecast has been studied.
