CAMx 2020 (2008-based) Projection Simulation

CAMx 2020 (2008-based) Projection Simulation

Introduction

We ran CAMx using emissions projected to 2020 to estimate future air quality in the Western U.S. CAMx simulation Base2020a_08 was derived from simulation Base 2008 version B (Base08b). All of the modeling inputs in simulation Base2020a_08, with the exception of the emissions, are identical to simulation Base08b. We also used the same version and configuration of CAMx. Details of the 3SAQS 2008 modeling platform, including the base and future year emissions inventories, are in the 3SAQS 2008 modeling protocol.


Results

Table 1 presents summary results showing Base2020a_08 daily maximum and differences in daily maximum between 2020 and 2008.
