CMB8 was originally developed as part of Contracts
5D1607NAEX and 5D2724NAEX between EPA’s National
Exposure Research Laboratory (NERL) and the Desert Research
Institute (DRI) of the University and Community College System

Substantial contributions to
initial development of the CMB8 model were made by DRI staff
members John G. Watson, Norman F. Robinson, Judith C. Chow,
Eric M. Fujita, and Douglas H. Lowenthal.

first since DRI to do so), and resolved many behavioral problems
with the model, now called EPA-CMB8.2.
