The present study analyzes the potential changes of residential heating and cooling degree-days as well as three stakeholder-relevant indices of agro-meteorological change (growing season length, sum of the active and sum of the effective temperatures) for Southeast Europe over near past (1975?2004), near (2021-2050) and far (2070?2099) future periods. All indicators were calculated from the output data of our simulations with the regional climate model RegCM driven by the ERA-Interim reanalysis for the near past ...

VERTICAL STRUCTURE OF SOME POLLUTANT OVER BULGARIA - OZONE AND NITROGEN DIOXIDE

(STEF92 Technology, 2018-11-20, Georgi Gadzhev)

Show more

The numerical simulations for the vertical structure of atmospheric composition fields over Bulgaria have been performed using the US EPA Model-3 system as a modelling tool for 3D simulations and the system nesting capabilities were applied for downscaling the simulations from 81 km to 9 km grid resolution over Bulgaria. The national emission inventory was used as an emission input for Bulgaria, while outside the country the emissions are from the TNO high resolution inventory. The air pollution pattern is formed ...
