MOBILE6 is a software program designed by the U.S. Environmental Protection Agency to estimate emission rates for the highway motor vehicle fleet under a range of conditions. MOBILE6.0 was released in January, 2002. This was the latest in a series of MOBILE models dating back to 1978 and was the first update in MOBILE since the release on MOBILE5b in 1996 and the first major update since the release of MOBILE5 in 1992. MOBILE6.2 is the first and latest update to MOBILE6 and adds the capability to estimate particulate matter (PM) and mobile source air toxics emissions. MOBILE6.2 contains very minor modifications to MOBILE6 for the parts of the model that estimate emissions of hydrocarbons (HC), nitrogen oxides (NOx), and carbon monoxide (CO). The original technical guidance for MOBILE6 was released in 2002. Changes to the model have necessitated an update to the technical guide. Most of this version of the technical guidance is unchanged from the 2002 version. |
