The Chemistry Transport by Deep Convection case will simulate the 10
July 1996 STERAO storm. The purpose of this simulation is to
assess the capability of each model to transport chemical species from
the boundary layer to the upper troposphere including the entrainment
of free tropospheric air. Parameterizations of lightning-produced
NOx will also be compared.
Primary species that will be compared are ozone (O3), carbon
monoxide
(CO), and nitrogen oxides (NOx = NO + NO2). O3
and CO are tracers
of transport, while NOx will include tracer transport and production by
lightning. Secondary species of interest are nitric acid (HNO3),
hydrogen peroxide (H2O2), and formaldehyde (CH2O).
