Bias correction techniques to improve air quality ensemble predictions: focus o...
Monteiro, A.; Ribeiro, I.; Tchepel, O.; Sá, E.; Ferreira, J.; Carvalho, A.; Martins, V.; Strunk, A.; Galmarini, S.; Elbern, H.; Schaap, M.; Builtjes, P.Five air quality models were applied over Portugal for July 2006 and used as ensemble members. Each model was used, with its original set up in terms of meteorology, parameterizations, boundary conditions and chemical mechanisms, but with the same emission data. The validation of the individual models and the ensemble of ozone (O-3) and particulate matter (PM) is performed using monitoring data from 22 backgrou...
Investigating a high ozone episode in a rural mountain site
Monteiro, A.; Strunk, A.; Carvalho, A.; Tchepel, O.; Miranda, A. I.; Borrego, C.; Saavedra, S.; Rodríguez, A.; Souto, J.; Casares, J.; Friese, E.A very high ozone episode with observed hourly values above 350 mug m(-3) occurred in July 2005 at the Lamas d'Olo air quality monitoring station, located in a mountainous area in the north of Portugal. Aiming to identify the origin and formation of this ozone-rich episode, a statistical analysis and a modelling approach were applied. A cross-spectrum analysis in the frequency domain and a synoptic analysis of ...
