5 1.0 INTRODUCTION This document provides information regarding how to use the MergeMaster database program. The MergeMaster Database is designed to manage the data commonly used in air dispersion modeling. MergeMaster is intended to supplement, but not replace, commercially available air dispersion model setup software. This database is designed to provide the information needed to model the air pollution concentrations surrounding a location, and to manage the information for several projects going on simultaneously.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
