Visualization and QA/QC of 1999 NEI

Purpose  

The purpose of this work is to help understand the most important source categories for precursors of haze in the MANE-VU region, and identify data gaps and abnormalities in the 1999 NEI inventory. Lessons learned will be used to improve the 2002 base year modeling inventory and focus inventory work on those source categories where improvements are necessary.

What Does it Entail?  
NEI 1999 version 2 was released in November 2002. Inventory summary tables and plots have been created providing a general overview of the 1999 inventory. This project will help states identify problems with the NEI.
