Eta-CMAQ air quality forecasts for O3 and related species using three different photochemical mechanisms (CB4, CB05, SAPRC-99): comparisons with measurements during the 2004 ICARTT study
Eta-CMAQ air quality forecasts three different photochemical mechanisms the 2004 ICARTT study
2010/8/12
A critical module of air quality models is the photochemical mechanism. In this study, the impact of the three photochemical mechanisms (CB4, CB05, SAPRC-99) on the Eta-Community Multiscale Air Qualit...
The number of very intense hurricanes striking the east coast of North America and the Caribbean could increase over the next century if ocean temperatures continue to rise. The total number of storms...
Skill prediction of local weather forecasts based on the ECMWF ensemble
Skill prediction local weather forecasts ECMWF ensemble
2009/11/12
Ensemble Prediction has become an essential part of numerical weather forecasting. In this paper we investigate the ability of ensemble forecasts to provide an a priori estimate of the expected foreca...

2009/11/12
Ensemble forecasts are run operationally since February 1998 at the Canadian Meteorological Centre, with outputs up to ten days. The ensemble size was increased from eight to sixteen members in August...
A comparison of predictors of the error of weather forecasts
comparison predictors error of weather forecasts
2009/11/11
Three different potential predictors of forecast error - ensemble spread, mean errors of recent forecasts and the local gradient of the predicted field - were compared. The comparison was performed us...
