Simulation Domain

 Western-US domain:  Allows analysis of ENSO cycles  Grid Cells:  12-km x 12-km  Decent for representing ubran vs rural influence on air quality  Historical Simulation Period:  1979-2008, which has several ENSO periods; PDO variability too long to capture  Boundary and Initial Conditions:  NARR (~32-km resolution)  Land-Use, Land-Cover Data:  NLDAS2 (save Alex’s dataset for WRF VIC-RHESSys-- no need to recalibrate VIC yet!)
