Abstract
Accurate modeling of photochemistry is critical and fundamental to reducing the uncertainty in air quality model predictions. A direct measure of this photodissociation is the photolysis rate. A refined module is being developed to simulate the actinic flux and photolysis rates of tropospheric species for air quality and tropospheric photochemistry modeling. The module will combine advanced radiative transfer models with explicit computations of photolysis rates using detailed information on (1) prevailing atmospheric conditions during simulation episodes, (2) satellite ozone and cloud coverage data, and (3) detailed characteristics of clouds, aerosols and surface albedo.
