| The development of the SARMAP
Air Quality Model has been applied in central
California including the San Joaquin Valley
and surrounding air basins, to prepare the 1994
State Implementation Plan. The model
has been extensively tested and evaluated using
the rich database of the San Joaquin Valley
Air Quality Study. The model passed
the model evaluation criteria of U.S. EPA and
the California Air Resources Board. The
model has many important attributes which include:
map projection capability to account for the
curvature of the Earth; telescoping grid capability;a
coordinate system that matches the coordinate
system of MM5 to avoid interpolation between
the two models; grid nesting capability (both
one-way and two-way nesting is possible); a
high resolution vertical
grid system (the thickness of the layer near
the ground is about 10 m); two chemical mechanisms
(Carbon-bond-IV and Statewide Air Pollution
Research Center (SAPRC)); a Plume-in-Grid module;
and three advection schemes. An aerosol
module is being incorporated into the model.
