Improving the spatial resolution of air-quality modelling at a European scale – development and evaluation of the Air Quality Re-gridder Model (AQR v1.1)

Autor: M. R. Theobald, D. Simpson, M. Vieno

Publikováno v: Geoscientific Model Development, Vol 9, Iss 12, Pp 4475-4489 (2016)

Currently, atmospheric chemistry and transport models (ACTMs) used to assess impacts of air quality, applied at a European scale, lack the spatial resolution necessary to simulate fine-scale spatial variability. This spatial variability is especially
