Using global-regional atmospheric modeling system Impacts of aerosols on climate Aerosol and radiation Aerosol and cloud Aerosol and water cycle Working Plan Setup WRF, WRF-Chem Model validation Update WRF-Chem's aerosol module based on GOCART, and using it as the initial and boundary conditions. The outermost WRF domain covers nearly the entire North American continent as well as much of the eastern Pacific Ocean and the western Atlantic Ocean. The vertical solid line indicate the time the program is executed. Assessing the Improvement of Severe Weather Prediction Over Western Africa in WRF by 3DVAR Data Assimilation System using Conventional and Radiance observational Data P. It is a 15 × 15 km 2 grid with points, resulting in a horizontal grid spacing of m. Once you have a configuration file, namelist. The 36-km domain covers much of the central and eastern Pacific (not shown), while the 1. 2 2 Domains d01 – 7. This document describes in depth the Weather Research and Forecasting (WRF) model configuration and improvements to surface parameters and the model surface state (e. Very very long time for updating my site, www. Therefore, this study presents a pre-paratory stage for the final overall aim. ncl" is larger than the actual one (created by WPS plotgrids. wps can be generated by:. We will conduct some experiments and if the problem will dissapear, the domain/simulation configuration will be modified upon next week.
