NEI Modeling Platform

WRF This category is focused on discussions related to how to set options to run WRF as inputs to the Emissions Modeling Platform. Chemical Speciation Issues Any Suggestions/Comments Spatial Surrogate Issues Run script Issues Collaborative Modeling Platform 2016 This category is for the 2016 Collaborative Emissions Modeling Platform. This platform is separate from other platforms for different years (e.g., 2011, 2016). You may have questions about how to use the scripts or the data files. If you find issues with any of the data or scripts, please submit those comments here so that they are tracked and searchable.
