This pre-generated result set aims to help the user consume the fleet weighted emission factor data for those common scenarios. An SQLite database has been generated using VEPM 7.0 calculation logic. The database contains the following scenarios matrix.

Below are parameters with the default value

Total Scenario = (50 years * 101 average speeds * 7 gradients * 56 temperatures) = 1,979,600 Scenarios
Click here to download results for 1,979,600 Scenarios

The SQLite database contains a table called "efc", It stored calculated total emission factors for each secenario.

How to view the result
You can open SQLite files using DB Browser for SQLite. You can download it from this link. This software is available for macOS, Windows, Linux(ArcLinux, Debian, OpenSUSE, Fedora), FreeBSD, etc.

Here is the tutorial on how to open database file.
For information about SQLite please go to SQLite Website.
