Emissions Science Improvements: Temporal and Spatial Allocations

Plans for improving temporal and spatial resolutions for air quality models.

Temporal Allocation Ideas by EIS Sector (xlsx) (14.05 KB, December 2021)

This document outlines our plans on which sectors need to be better assessed/improved for their temporal characterization in the 2020 NEI. This is important especially for the year 2020 since it was a COVID year, and it is expected that there will more needs for data a higher temporal level, especially for the nonpoint and mobile source categories, which are inventoried at an annual level in the NEI.
